Austin Marathon Mashup with Google Maps, USGS Elevation Data, and ESRI Elevation ServiceGeoChalkboard
sur Planet Geospatial - http://planetgs.com

I’m training for the upcoming Austin Marathon and Half Marathon and thought it would be cool to put together a simple mashup showing elevation information for the course. The terrain for this particular race can be pretty challenging. So, what I’ve done is put together a quick mashup using a variety of resources including the Google Maps API, the USGS Elevation Query Web Services, an elevation profile REST service from ESRI, and Dojo to tie everything together. It’s nothing fancy, but you can see the final product here.

To find the elevation at any mile marker along the marathon route simply click the marker and the application will query the USGS Elevation Query Web Service to determine the elevation in meters at that point. To see an elevation profile for the entire course, click the ‘Get Elevation Profile’ button which uses the ArcGIS JavaScript Extension for the Google Maps API along with the ProfileService task.

In this post I’ll detail how I quickly put together this mashup.

Google Maps API

Obviously the base map for this mashup is Google Maps so we reference the API to create our map and then add the marathon mile markers and route. I’m not going to go into much detail on creating the base map. If you need basic information on the Google Maps API you can download a free copy of our Introduction to the Google Maps API e-learning course. I will point out that we are reading in the mile markers for the marathon from an XML file as seen in the code example below. For more information on reading XML files from Google Maps please review a previous article on the subject.

We follow a similar process for adding the marathon route wherein we create a new instance of GPolyline by feeding in an array of GLatLng objects that define the route.

ArcGIS JavaScript Extension for Google Maps

Next, to display a terrain profile for the marathon route we are going to use the ProfileService which is a task published by ESRI. To take advantage of this task we need to import a reference to the ArcGIS JavaScript Extension for Google Maps which allows you to plot the results of a geoprocessing task like the ProfileService on top of a Google Map. Below you will see the reference to this API.

Next, we need a reference to the ProfileService.

The ‘Get Elevation Profile’ button triggers a call to the ‘generateProfile()’ function seen below.

I will call your attention to a few lines of code in generateProfile(). The first line creates a new instance of the Google Maps API object GPolyline by calling a JavaScript function which loads the points of inflection for the marathon route.

The next few lines below that create ArcGIS Server JavaScript API objects for FeatureSet and Feature. The instance of FeatureSet is created by referencing the GPolyline object that we initially created in the function. Finally, we create various task parameters that will then be used as input when we execute the task against ProfileService.

Task parameters include the instance of FeatureSet that we created from our GPolyline object along with parameters to define the output image width and height of the profile and a boolean value indicating whether or not we want the segments of the route to be displayed in the elevation profile. We do not in this case because the large number of points that define the route will simply clutter the output terrain profile. Our last line of code in this function calls the execute() method against profile task. Note that we feed in our task parameters, a second parameter that indicates whether or not we want the results to be returned as KML in the form of a GGeoXml object, and finally a callback function that will execute when the task has finished. ProfileService is a synchronous task meaning that the application will wait until the results have been returned to continue functioning. In this case, the function profileCallback() will be run against the results of the service.

A FeatureSet object is returned from the task. In this case, the FeatureSet contains a Feature which represents the marathon route. A Feature can contain both the geometry of the feature as well as attribute information. In this case we aren’t concerned with the geometry since we already know the marathon route. The attributes though contain the terrain profile information including a path to the URL where the output terrain profile image was placed along with some additional information that describes the profile. Finally, as is indicated in the highlighted section of the profileCallback function above we define an HTML snippet in the form of a tag that contains a pointer to the URL of the terrain profile image along with the profile description. This HTML is then placed inside a Google Maps API info window and displayed at the center point of the route.

USGS Elevation Query Service

Clicking a mile marker or any point along the route triggers a call to the USGS Elevation Query Service and displays the results just above the map. To access the USGS service we are going to use the dojo.io.script.get() method which is part of the Dojo JavaScript framework. We’ve written extensively about the Dojo framework on this site and provide a general overview here. Take a look at the code below and then we’ll discuss how this is accomplished below.

We are going to wrap everything inside a Google Maps event listener which ‘listens’ for a click on the map. You can see this in the first line of code above. Events in Google Maps are registered with the GEvent object and the addListener() method. The addListener() method takes three parameters. The first is the object (an instance of GMap2 in this case), the second is the event to listen for on the object, and the final parameter is a function that will run in response to the event. So in general terms we are setting up a function that will execute anytime the user clicks the map. We need this event listener to detect when the user clicks on a mile marker or a point along the route. Inside the function is where all the work takes place to respond to the event. I’ll draw your attention to a few pertinent lines. We need a reference to the USGS Elevation Query and we provide that in the first line that I have highlighted above. However, this provides only the base URL. We also need to append the latitude and longitude where the user clicked to the URL and this is accomplished in the second line that I have highlighted above. Now, in this case we are only providing the elevation for a mile marker or a point along the route rather than any point the user clicks on the map. The ‘click‘ event on GMap2 passes different arguments based on the context of the click, and whether or not the click occurred on a clickable overlay. You can see this in the event listener below.

If the click does not occur on a clickable overlay (this would be GMarker, GPolygon, GPolyline, or GInfoWindow), the overlay argument is null and the latlng argument contains the geographical coordinates of the point that was clicked. If the user clicks on an overlay that is clickable (GMarker or GPolyline in our case), the overlay argument contains the overlay object, while the overlaylatlng argument contains the coordinates of the clicked overlay.

So for our application we only want to call the USGS Elevation Query if the use has clicked on a mile marker (GMarker) or a point along the route (GPolyline). That accounts for our ‘if’ statements on ‘overlay’ and ‘overlayLatLng’ as seen in the code example above.

That was a bit of a lengthy description about a small subject in the overall scheme of the application, but it was necessary to fully describe the GMap2.click event.

Now we get to the heart of the matter which is calling the USGS Elevation Query Service with the latitude, longitude coordinate pair of either a mile marker or a point along the route. Here is where we are going to make use of Dojo and its capability of making cross-domain requests with JSONP. JavaScript’s Xm [HttpRequest] object does not allow you to load data from outside of the page’s current domain because of the same origin policy. However, it turns out that tags are not subject to the “same origin” policy. JSONP is an informal standard that that has been developed to allow data to be take advantage of cross-domain loading. Dojo provides the dojo.io.script.get() method to handle JSONP functionality. Refer again to the code above and pay particular attention to the final area that I have highlighted in the listener function. The get() method takes a single object literal parameter that can contain various properties including the url that will be called [ws.geonames.org] Other properties of note include ‘load’ and ‘error’ functions. The ‘load’ function is passed a response object which in our case will contain the elevation of the point that was clicked. The ‘error’ function would, as its name implies, be called in the event of an error. Our ‘load’ function takes the elevation value passed in the response object and places it inside our web page as seen below.

So there you have it. A simple, but useful mashup for obtaining elevation information related to the upcoming Austin marathon.

Import PostGIS – Support de DXF
sur Oslandia

Quand une figure aussi connue du monde de la géomatique se met au hype 2.0 (TM), on peut se dire que le monde avance. Ou l’inverse.

Faut il rappeler que Frank Wamerdam est le principal développeur de la bibliothèque GDAL/OGR, mais aussi actif sur des sujets aussi divers que OGR WCTS, JPEG2000 / GeoJP2(tm), Microstation DGN/ISFF, OGDI , Shapelib, GeoTIFF, Imagine, Arc/Info Binary Grid Format, GRASS, SDTS, ISO8211Lib, UK NTF, GXF3, S-57 (ENC), NOAA/MAPTECH BSB, PROJ.4, OpenEV, GML, PCIDSK SDK, MapServer, j’en passe et des meilleurs.

Sans oublier son rôle indispensable à l’OSGeo en tant que «charter member».

Venons en au fait, Frank se met au blog ! Et comme le mentionne notre ami Guillaume Sueur sur neogeo-online, le premier post de Frank Wamerdam est de qualité, à la hauteur des messages qu’il envoie régulièrement sur les mailing list des projets de son entourage. Il y décrit donc l’implémentation en cours du support de DXF dans la bibliothèque OGR. Apparemment ce n’est pas de tout repos, même si le format est documenté par Autodesk il reste nombre de points problèmatiques, qui sont cependant en cours de résolution.

On peut donc tester dans la version SVN de GDAL. A vos compilateurs, renvoyez les bugs ! Et on peut dans tous les cas annoncer que l’on a un nouveau moyen d’importer des fichiers DXF dans une base PostGIS grâce à ce nouveau driver, ce qui fera plaisir à nombre d’entre vous, le sujet étant souvent un point bloquant.

Merci à Frank, et aux sponsors de ce projet, la ville d’Uster en Suisse.

Southern California Marine Protected AreasThe Swordpress
sur Planet Geospatial - http://planetgs.com

The South Coast Marine Life Protection Act (MLPA) process has been underway for a while now. Recently, the Blue Ribbon Task Force (decision makers) put forth their Integrated Preferred Alternative, combining three different marine protected areas (MPA) proposals. The process is moving toward adopting MPAs, but a lot of people are still up in arms about losing Southern California’s best fishing locations. So I set out trying to figure out if these claims were true.

There are a ton of fishing websites out there, and I came across two that have GPS locations for the *best* fishing areas in Southern California posted to their sites. With these lists of GPS points, I created a spreadsheet, converted the lat/longs to a GIS-friendly format, created shapefiles from these tables, and overlayed these points with the recently-proposed protected areas. And what do you know? Very few of the (independently determined) best fishing sites actually fall within the protected areas. Take a look…click on the image for a larger version.

Satellite Imagery Used to Combat Surge of Pirate Attacksgot geoint?
sur Planet Geospatial - http://planetgs.com

The surge of pirate attacks off of Africa has become a major issue for the shipping industry and global trade in general. There has been an estimated 125 attacks and 45 ships were actually seized by pirates in the past two years. Experts believe that the number of attacks could be higher, as piracy is believed to be widely under-reported. And, GEOINT will be playing a major role in stopping the spread of piracy. Adm. Jim Stavridis, Supreme Allied Commander Europe (SACEUR), recently said that “more ships would be helpful” to counter piracy off Somalia but that “what I’m really after is maritime patrol aircraft, NATO AWACS [Airborne Warning and Control System] and satellite images.”

Adding Streetside and Enhanced Birds Eye To Your ApplicationsBing Maps Blog
sur Planet Geospatial - http://planetgs.com

Well, it didn’t take long for us to add these features to the already robust set of APIs in the Bing Maps Platform, now did it? In case you’ve been in some analog state without Internet access you should first read, “Bing Maps Adds Streetside, Enhanced Bird’s Eye, Photosynth and More.” Starting today, you can download the required DLLs for adding Bing Maps Streetside(TM) and Enhanced Bird’s Eye to your applications. Let’s just get right to it, shall we?

First thing you need to do is download the new DLLs from Microsoft Connect. You will actually download a .MSI (Microsoft Installer) which will install the Bing Maps Silverlight Control Extended Modes Beta SDK (wow, that’s a mouthful) and also drop the Microsoft.Maps.MapControl.ExtendedModes.dll onto your hard drive typically at [Program Files (x86)]\Bing Maps Silverlight Control Extended Modes\Beta\Libraries\.

Second, there are new versions of Microsoft.Maps.MapControl.dll and Microsoft.Maps.MapControl.Common.dll. You will need to download this .MSI as well; however!, you will also need to uninstall the current version (yes, backwards compatible). The version you have is 1.0.0.0. You will now be using 1.0.1.0. This is very important as your application will not work if you aren’t using the new version of the DLL.

Now, add them to your Silverlight project in the References folder.

In your XAML file (I’m using the default template, MainPage.xaml) you’ll want to add namespace and assembly references to Microsoft.Maps.MapControl.dll. Next, we’ll add a Bing Silverlight Map to your web application; and, we’ll configure it a bit to center over a place where Streetside is available. Your code should look something like this:

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    xmlns:m="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl">







Notice the [BINGMAPSKEY]. You need a key to authenticate against the Bing Maps Silverlight Control. To get one, just got to BingMapsPortal.com and get one.

There are two ways to add Enhanced Birds Eye and Streetside to your applications - (1) by inserting them into the navigation; and/or, (2) using the map mode extension classes built into the map control.

Adding Streetside and Enhanced Birds Eye to the Navigation Control

If you simply want to add Enhanced Birds Eye and Streetside to the default navigation bar (it shows up between Aerial and the [using declaration. The follow code sample shows you how to insert both Enhanced Bird’s Eye and Streetside into the navigation bar:

using System;

using System.Windows.Controls;

using Microsoft.Maps.MapControl.ExtendedModes;

using Microsoft.Maps.MapControl.Core;

namespace SilverlightApplication1

{

    public partial class MainPage : UserControl

    {

        public MainPage()

        {

            InitializeComponent();

            //Add Bird's Eye to Navigation

            BirdseyeMode.AddModeToNavigationBar(myMap);

            //Add Streetside to Navigation

            StreetsideMode.AddModeToNavigationBar(myMap);

        }

    }

}

Adding Streetside and Enhanced Birds Eye to Custom Controls

For those of you who want to control your users destiny, we also have methods for you to change the map mode with button clicks, onload events, etc. So, in order to change the map mode to Enhanced Birds Eye and/or Streetside you will instantiate the map modes using the Map.Mode class. Also note, the other map methods will still work with this, so you can also re-center or zoom the map in the new mode (as illustrated below). You’ll need to add an additional using declaration for the Core control if you choose to do so.

The following loads Enhanced Birds Eye when the map loads:

using System;

using System.Windows.Controls;

using Microsoft.Maps.MapControl.ExtendedModes;

using Microsoft.Maps.MapControl.Core;

namespace SilverlightApplication1

{

    public partial class MainPage : UserControl

    {

        public MainPage()

        {

            InitializeComponent();

            myMap.Mode = new BirdseyeMode();

            myMap.Mode.Center = new Microsoft.Maps.MapControl.Location(25.859768, -80.119764);

            myMap.Mode.ZoomLevel = 17;

        }

    }

}

The following loads Streetside when the map loads:

using System;

using System.Windows.Controls;

using Microsoft.Maps.MapControl.ExtendedModes;

using Microsoft.Maps.MapControl.Core;

namespace SilverlightApplication1

{

    public partial class MainPage : UserControl

    {

        public MainPage()

        {

            InitializeComponent();

            myMap.Mode.Center = new Microsoft.Maps.MapControl.Location(47.615594, -122.20136);

            myMap.Mode = new StreetsideMode();

            myMap.Heading = 20.3;

            myMap.Pitch = 12.3;

        }

    }

}

Notice, I used the heading and pitch properties. Heading is effectively the compass direction and pitch is the angle at which you’re viewing. Here are the official definitions: Heading is the compass direction, expressed as a double. A value of 0 is true north, and a value of 180 is true south. Values less than 0 and greater than 360 are valid and are calculated as compass directions. The pitch direction, expressed as a double. A value of 0 is level and a value of -90 is straight down. Values less than -90 or greater than 0 are ignored, and the pitch is set to -90.

So, there you go. Now, go download the new DLLs from Microsoft Connect and make your applications great(er). And, don't forget about the Bing Maps Platform Web Cast - Fall 2009, Release today @ 10AM PST.

Jo Cook: Cool things no 1: GvSIG Mobile
sur Planet OSGeo

I’ve been looking at a couple of “cool things” recently that don’t seem to have picked up much coverage in the blogosphere, so I’m going to do a series of occasional posts on them. The first is GvSIG Mobile and the Tellus Project.

GvSIG Mobile is a development from Prodevelop in Spain, to create an optimised version of GvSIG for small-screened mobile devices such as smartphones and netbooks. The Tellus project links GvSIG mobile with an embedded mobile database, and allows you to synchronise with a remote database, eg PostgreSQL either on demand or when you choose (eg when you have a data signal), using OpenMobileIS.

What you get is a GIS package, allowing you to add base mapping either from your local device or via WMS, and the ability to edit a vector layer on top using on-board GIS or by drawing on the screen. You can add attribute data, and store it locally, then synchronise with a remote database, with full conflict resolution. All in open source- just install it on your device of choice!

We think this is fantastic. In it’s current very simple form, we can see many uses for this as, say, a simple remote issue-recording device. We’re adapting this for use as a full relational on-site recording tool for archaeologists, but it could easily work for environmental staff or anyone trying to record data outdoors, perhaps in areas where there isn’t always a good 3G signal.

Cool things no 1: GvSIG MobileComputing, GIS and Archaeology in the UK
sur Planet Geospatial - http://planetgs.com

I’ve been looking at a couple of “cool things” recently that don’t seem to have picked up much coverage in the blogosphere, so I’m going to do a series of occasional posts on them. The first is GvSIG Mobile and the Tellus Project.

GvSIG Mobile is a development from Prodevelop in Spain, to create an optimised version of GvSIG for small-screened mobile devices such as smartphones and netbooks. The Tellus project links GvSIG mobile with an embedded mobile database, and allows you to synchronise with a remote database, eg PostgreSQL either on demand or when you choose (eg when you have a data signal), using OpenMobileIS.

What you get is a GIS package, allowing you to add base mapping either from your local device or via WMS, and the ability to edit a vector layer on top using on-board GIS or by drawing on the screen. You can add attribute data, and store it locally, then synchronise with a remote database, with full conflict resolution. All in open source- just install it on your device of choice!

This week, the US Air Force confirmed that it is flying a stealth unmanned aircraft known as the “Beast of Kandahar,” a drone spotted in photos and, until now has been shrouded in secrecy. The RQ-170 Sentinel is being developed by Lockheed Martin and is designed “to provide reconnaissance and surveillance support to forward deployed combat forces,” the air force said in a brief statement. Aviation experts dubbed the drone the “Beast of Kandahar” after photographs emerged earlier this year showing the mysterious aircraft in southern Afghanistan in 2007. Read more here.

Google Maps of Mankato, Minnesota
sur Google Maps Mania

The City of Mankato's Maps
The city of Mankato in Minnesota is using Google Maps to provide a wealth of local information and data about the city to its local residents. The maps include crime maps, maps of local amenities and garbage collection times.

The Mankato Police Calls For Service Map uses Google Maps to provide crime information for the city. Information on the map can be narrowed by type of crime, date range, neighborhoods and political wards.

The Garbage Pickup Schedule Map uses shaded overlays on Google Maps to show on which days garbage trucks will be collecting in each of the city's neighborhoods.

The Parks and Amenities Map allows residents to find local amenities. Amenities can be searched on the map under a number of categories. For example if you fancy a game of basketball you can click on basketball courts and all the city's public courts are displayed on the map.

SPAR 2010 – Mobile Mapping ShowcaseLiDAR News
sur Planet Geospatial - http://planetgs.com
1. Mobile mapping is the hot platform.
2. SPAR 2010 has 7 of the leading mobile mapping vendors signed up to demo their rigs.
3. The ROI for SPAR 2010 is going to be very high.
I think it is fair to say that mobile mapping is the hottest laser scanning technology platform on the market. If you want to be at the center of the mobile laser scanning universe you had better plan to attend SPAR 2010 in Houston, TX, February 8 – 10. At last report there will be 7 mobile mapping vans on display, along with a number of mobile mapping technical sessions, and a Mobile Mapping Boot Camp for those who are just getting involved. This is going to be the place to compare and contrast all of the key players, in person.

In addition to the mobile mapping track and Sunday Boot Camp, there will also be Civil and Plant Boot Camps and sessions. There will also be a security/forensics track, BIM, mining, digital heritage, new 3D technologies – the list goes on. From the agenda it appears that this will be the best SPAR event to date, so if you want to make a good investment to kick off the new year this would have to be at the top of the list.

Links: Audi A8 with Google Earth, Liquid Galaxy, Deer Hunting, StreetView in the snowGoogle Earth Blog
sur Planet Geospatial - http://planetgs.com

Audi A8 with Google Earth: The new Audi A8 comes with a lot of neat toys, including integrated Google Earth! The car connects to the internet via 3G, which it uses for a variety of purposes. It pushes the 3G out via wifi for anyone in the car that needs it (similar to the Verizon MiFi), and it also streams Google Earth imagery to the navigation system.

Detailed information about the Google Earth integration is lacking, but you can see it in action for a just a few seconds in the video below (skip ahead to the 7:24 mark). It shows 3D buildings (some photorealistic, some gray), just like you'd see in Google Earth.

Liquid Galaxy: At Google I/O earlier this year, they showed off a cool thing they called the "Holodeck" -- a 360 degree booth that surrounds you with StreetView imagery. They've now renamed it "Liquid Galaxy" and integrated a special version of Google Earth to work with it. They've brought it to the COP15 conference in Copenhagen, and they'll be bringing it to other conferences in the future. I hope to maybe try it out at Where 2.0 this spring.

Deer Hunting with Google Earth: A man in Illinois shot a 25-point buck after studying Google Earth to determine probable routes that the deer would take. He staked out his position based on that information and was able to get his shot just before dusk. It turned out to be a lucky shot (deflected off a tree branch, pierced the deer's ear, which then fell down a bank into the creek and drowned), but it's interesting that he used Google Earth to find the best location.

StreetView in the snow: A few days ago, in preparation for the 2010 Winter Olympics, Google hit the slopes in Vancouver and captured some StreetView imagery using a snowmobile outfitted with their cameras.

I would have to guess that the development of the StreetView trikes helped make this possible, as it was likely a similar system.

No word on a release date for this imagery, but the Olympics begin on February 12, so I'm sure we'll see it sometime before then.

Make your Server Object Extensions exception friendlymap butcher
sur Planet Geospatial - http://planetgs.com
I’m working on a project where I’ve applied the following simple design principle:

“Don’t use ArcObjects unless you have to”

Most of the spatial functionality is delivered via a set of web services and is implemented directly between a custom WCF application server and Oracle (ESRI’s flavour of ST_Geometry). I took this decision for the following reasons:

1. I didn’t want to overly complicate what are essentially simple spatial processing steps

2. I wanted to reduce the number of layers within the application as much as possible

3. I wanted to make the services as fast as possible

However there are cases when I have no option and I have to use ArcObjects – I have implemented the functionality within a Server Object Extension (SOE) hosted within an ArcGIS Server Map Server context which I make remote calls to from the application server. Works Sweet.

For a long time our test manager has been busting my nuts about the crap error messages which are received back from the SOE when an exception occurs, this is basically because I’ve never implemented a useful exception class for my SOE – so this afternoon I did just that. Basically what I wanted was the ability for the application server to make calls onto the SOE and catch the custom exception. The communication between the application server and ArcGIS Server is via DCOM so I have a local instance of the SOE assembly referenced by the application server which means that I can do this:
catch (LRSSpatialServerException sEx) { throw new LRSException(ProcessStepType.error, “validateDerivedDistance”, sEx.Message + ” : ” + sEx.RunTimeMessage, id); }
```
catch (MyCustomSOEException SoeEx)
 
{
 
...do something
 
}
```
However the important thing is to ensure that your custom exception is serializable so that when it is thrown by the SOE it can be serialized/deserialized on the application server. Here’s how you do that:

1. Mark the class as serializable:
```
[Serializable]
 
public class MyCustomSOEException : Exception
 
{
   string foo;
}
```
2. Override the base Exceptions Serializable constructor to implement deserialization
```
protected MyCustomSOEException (SerializationInfo info, StreamingContext context)
 
: base(info, context)
 
{
 
this.foo= info.GetString("foo");
 
}
```
3. Override the GetObjectData method to implement serialization
```
public override void GetObjectData(SerializationInfo info, StreamingContext context)
 
{
 
info.AddValue("foo", this.foo);
 
base.GetObjectData(info, context);
 
}
```
The Exception class is now ready to be passed back and forth between the application server and the SOE. For example in the catch block on the application server side we can access any custom exception properties if the SOE throws:
```
catch (MyCustomSOEException SoeEx)
 
{
 
string exceptionProperty = SoeEx.foo;
 
}
```
The same methodology can be applied to any objects you wish to return from a method call onto your SOE. As long as they’re safely serializable then you’re good to go – Making custom exceptions serializable is particularly important if your developing a server object extension for use by others.

A Higher Education, Part 3lost in spatial
sur Planet Geospatial - http://planetgs.com

After all that we had stability, but not performance.

It turned out that one of the causes of instability was also implicated in the performance problems, but for entirely different reasons. Because of complicated, low-level computer programmer thingummybobs, a single connection from SIS to PostGIS (where EDINA store national coverage of both OS MasterMap Topography Layer and OS Strategi) had to be synchronous, i.e. not multi-threaded. As in Part 2, this was not a problem for normal GeognoSIS usage, where each client connection has an independent connection to PostGIS, but for highly concurrent OGC WMS requests, it meant that, realistically, each request was queued until the current one was finished. This explained why the average request time was high, and why the big beast server running PostGIS was hardly being exercised at all.

As luck would have it, it is easy and fast to create a new PostGIS connection for each request, and so immediately performance was back on a par with the open source WMS implementation.

But parity is not good enough. We carried out lots of additional testing, profiled lots of code, and were able to identify several additional bottlenecks. Some of these were an unforeseen side-effect of changing our EPSG code lookups from impossible-to-maintain static tables in code, to a easy-to-manage database that is automatically generated (and therefore automatically up to date) during the SIS build process. That database not only had its own multi-threaded locking, but was being queried far too often in some cases.

After finding and fixing these additional bottlenecks, we ended up consistently, measurably faster than the open source WMS (as tested by EDINA, not evil old me).

As well as passing the Performance Acceptance Test (PAT), GeognoSIS was used, via OGC WMS requests, to generate over ten million tiles for the map cache that backs the Digimap website with no crashes, no memory leaks, and no performance degradation. Job done!

Stability fixed? Check. Performance fixed? Check. Anything else? Yes: in Part 4, published tomorrow.

Fréquentations des sites ESRI / Autodesk / OpenLayers

sur HelioMap

Par simple curiosité, j’ai tapé dans Google Trends les webmappings qui m’intéressent et plus spécialement ArcGis Server, MapGuide et OpenLayers .

Google Trends est un outil issu de Google Labs permettant de connaître la fréquence à laquelle un terme a été tapé dans le moteur de recherche Google, avec la possibilité de visualiser ces données par région et par langue.

Source

Cet outil est très utile pour les référenceurs de sites. Il permet de comparer, d’analyser les mots clefs recherchés à partir du moteur de recherche Google.

L’analyse s’effectue sur toutes les années référencées par Google.

D’après le graphique, MapGuide est référencé dans Google avant 2004 vis-à-vis de ces concurrents. Son index de volume de recherche est assez stable mais diminue progressivement d’années en années. ArcGis Server et OpenLayers apparaissent entre 2006 et 2007 et connaissent une croissance qui se stabilise dans le temps.

Pour MapGuide, la majorité des recherches se déroulent sur le continent Asiatique et Européen (Taiwan /Malaisie et Grece). La langue la plus utilisée est le slovaque, le tchèque et le grec.

Pour ArcGis Server, les pays de prédilection sont la Chine, l’Inde et l’Afrique du Sud. Les langues utilisées sont le chinois, le grec et l’anglais.

Les recherches sur OpenLayers se basent plus sur le continent européen. (Norvège, République Tchèque, Finlande). Les langues sont le norvégien, le tchèque et le catalan.

Une grande partie des recherches s’effectue sur le continent nord américain, européen et asiatique. La langue qui prévaut est l’anglais. Le seul défaut de cet outil est qu’il ne chiffre pas le volume des recherches : The numbers you see on the y-axis of the Search Volume Index aren’t absolute search traffic numbers. Une extrapolation de l’information vous indique quand même où se déroule la majorité des développements de ces produits et de connaître les articles du moment.

Une petite précision, si on réalise cette étude sur les douze derniers mois, on obtient le graphique suivant.

Le volume de recherche est stable pour les 3 webmappings même si MapGuide reste en dessous de ces concurrents. Pour finir, voici les articles du moment les plus recherchés:

In this blog, I talk about open source geospatial software, cool mapping applications and toys... and anything I might find of interest.

My name is Daniel Morissette, I am an open source geospatial software developer, mostly interested in webmapping and data access and distribution. I have been an active developer and user of open source geospatial software since 1999 and have led and/or contributed to several open source projects over the years, the two main ones being MapServer and GDAL/OGR. I am an active member of the Open Source Geospatial Foundation (OSGeo) and several of my posts will relate to projects and activities of the OSGeo community.

I also have entrepreneurial tendencies, and after co-founding DM Solutions Group in 1998, I have been leading Mapgears since 2006. We are based in Chicoutimi, Quebec and our team provides technical support, training and software development services to users of MapServer and related Open Source Web Mapping technologies.

This blog is bilingual (English/French), with the English posts targeted at the international geospatial community, and the French ones targeted at the Quebec and to some extents the global Francophone geospatial community. Some posts may be translated and others not, depending on the topic and the target audience.

UK Government to offer 'free' postcode data?Home

The BBC are reporting that the UK Government are planning to offer UK postcode data for free from April 2010.
The dataset that will probably be 'freed' is the geographic coverage data for each postcode, and not the Royal Mail PAF dataset which links individual addresses to postcodes. Exactly how the data will be offered and under what conditions are still being decided. So, in common with the recent Ordnance Survey announcement, we should probably wait until the data is actually released before deciding how big a step forward this actually is.
