Today's 30DayMapChallenge is - Prompting Only
Yesterday Andy Woodruff posted this animated contour map:
...Dear all,
The CRO is pleased to announce the list of new OSGeo Charter Members.

Have you ever wondered how many satellites have passed overhead while you've been going about your daily business? Probably quite a few. But how many of them were actually looking at you? Watched is an intriguing new interactive map which attempts to answer that question by revealing which satellites have passed over any location on Earth during the last seven days, and, more interestingly, which of them actually took a photograph.
Visit Watched and enter any location in the world. The map will then reconstruct the satellite activity above that spot over the previous week, identifying the satellite that passed within viewing range and searching public satellite imagery archives for photographs captured during those passes.

There is something undeniably romantic about casting a message in a bottle into the ocean. After all, what could be more enchanting than surrendering a personal secret to the tides, with nothing but the hope that it might one day wash ashore and find its way into a stranger's hands?
Tell the Sky takes this idea to the skies. However with this interactive map, instead of throwing a bottle into the ocean, you write a message on a glowing virtual lantern and release it into the wind. Carried by real-world wind currents, your lantern drifts across the world until someone catches it, reads your message and adds one of their own before sending it on its way again.

Today's #30DayMapChallenge is Utopia.
There have been lots of pixel-art maps appearing online recently. I covered several of these projects in my recent Pixelate the World post. For today's challenge I thought it might be interesting to create a pixelated map of London â not as it is, but as it might look in an ideal world.
Greater London covers approximately 1,591 square kilometres. If each zoomed-in map tile covers roughly 0.15 square kilometres, I would need in the region of 10,600 images to create enough tiles to cover the entire capital. That's a few too many for a simple map challenge, so I decided to create a much smaller map - using just one tile - of Trafalgar Square.
...
Today's #30DayMapChallenge is 10 minute map.
My Mount Fuji map took 30 seconds.
Vibe-coding might be cheating (and perhaps even the end of civilisation as we know it), but it really can help developers create online maps very, very quickly. To create my map, I simply entered the following prompt into ChatGPT:
'I have downloaded a geojson of Mount Fuji. Can you give me the code for a three.js illuminated neon contour map. Add an animation to rotate around the center of the mountain. My geojson URL is https://mapsmania.github.io/mapchallenge/contours.geojson'
It then took me 30 seconds to download and run the resulting HTML file. Job done!
...
For thousands of years, cartographers have been mapping more than just the known world. Medieval and early modern maps often mixed observed geography with religious beliefs, folklore and mythical stories, placing legendary cities, lost kingdoms and biblical locations alongside real-world places.
Mythical Tours is a fascinating narrated journey through this imaginary geography, using centuries of historical maps to track down the locations of places that many people today believe exist only in legend.
...
If your children are too young to enjoy Untappd, you could introduce them to Birds Around the World instead. With this map, rather than tracking all the beers they've drunk, they can collect all the different birds they've discovered! Get them started with binoculars and field guides rather than pints and beer goggles.
Birds Around the World is an interactive 3D globe that allows children to explore the world's birdlife. Hundreds of bird species are represented on the globe, with each dot marking where a particular species can be found. Click on a bird to discover a photograph, its conservation status, what it eats and, best of all, a recording of its actual bird call.
...
Before mobile phones, radio and even the telegraph, fire beacons were used as an early warning system designed to alert communities to the approach of hostile forces. The beacons were deliberately positioned on prominent high ground, allowing one fire to be seen from another. When an enemy was spotted, a chain of burning beacons could then relay the warning across the landscape.
The system was particularly important during the threat of invasion by the Spanish Armada in 1588. Beacons could take various forms, from simple bonfires to barrels of pitch or iron fire baskets mounted on tall wooden poles. Some were substantial enough to have permanent structures.
...
On October 19, 2026 the GeoServer project announced three releases: 3.0.2, 2.28.6 and 2.27.7. For most deployments these are maintenance and security updates. For organizations that must run their geospatial infrastructure under formal cryptographic requirements, 3.0.2 carries something more: a new FIPS community module, developed by GeoSolutions, that lets GeoServer run on top of a FIPS 140-3 validated cryptographic module. In this post we look at what the module enables, the engineering behind it, and what teams should plan before adopting it.

In October, YouGov published a small-multiple visualisation showing the popularity of regional names for alleyways in the UK. The maps in What else do Britons call an alleyway? are based on survey data. YouGov asked 39,224 Britons which words they personally use to describe an alleyway. The resulting maps show the percentage of people in each county or region who use particular terms.
I thought it might be interesting to also map the different words for alleyways that actually appear in street names around the UK.
...
If you want to know what happened in yesterday's midterm elections, you should probably start with The Economist's Swing from 2024 map. The map is paywalled, but the screenshot above tells the story rather well: almost the entire USA (perhaps with the exception of South Dakota) swung towards the Democrats.
...
Non-Governmental Organizations (NGOs) are key actors in the conservation and restoration of ecosystems worldwide. However, practice-oriented conservation groups face a major hurdle: evaluating the real-world impact of their management activities over large geographic areas. Traditional monitoring methods rely on labor-intensive on-the-ground surveys, which are difficult to sustain at scale. While satellite Earth Observation (EO) data, such as Copernicus Sentinel-2, offer wide-scale coverage and long-term time series, using them effectively requires complex domain knowledge, spatial data handling, and specialized data processing skills.
This weekâs challenge is:
...
Today's #30DayMapChallenge is Polygons.
At the risk of starting World War III, I've created a map of Poland's Historical Borders. The map uses polygons to show how Poland's borders have changed at different points in its history. The historical boundaries were downloaded from OpenHistoricalMap.
...
It seems astonishing to me now that only a fortnight has passed since I climbed to the roof of Maps Mania Tower and proclaimed to the world that the Age of the Pixel Map had begun. And yet here I stand before you today, bearing the sad news of its demise and announcing, with no little ceremony, that The Era of the Voxel Map Has Arrived.
Two weeks ago, I observed that "One notable limitation shared by most of these pixelated maps is their single, fixed perspective." My proposed solution was to create a pixel map offering four distinct viewpoints: North, South, East and West.
...
For Day 2 of the #30DayMapChallenge, the theme is Lines. For my contribution, I've created MapterGLOW, an interactive 3D terrain map that turns elevation data into glowing neon contour lines.
The map uses elevation tiles from Mapterhorn to build a three-dimensional model of the landscape, overlaid with luminous cyan contour lines at 50-metre intervals. You can rotate the terrain, tilt the camera and zoom in and out to explore the topography from different angles.
...
As part of our Security project for QGIS initiative, we identified a work package titled âImprove Memory Safety.â
Having worked on this topic over the last few months, here is a summary of the issues involved and what has been accomplished so far.
Itâs not an easy thing to present this topic. Iâll try not to dive into too much technical details to focus instead on the broader objectives and implications.
...
What if every European capital sent out a car at exactly the same moment, with the aim of reaching every town and village in Europe before its rivals? Which capital would claim the most territory, and how far would its influence extend beyond its own national borders?
If Every European Capital Sent Out a Car at the Same Moment is an intriguing interactive map from Copilot Travel that attempts to answer these questions. It imagines 38 cars setting off simultaneously from 38 European capitals, with each car travelling outwards along the road network at typical driving speeds. Every location in Europe is then assigned to whichever capital's car can reach it first.
...
Recently, I was very impressed by 10 Years, 10 Adventures, a collection of ten WebGL-powered animated travel maps featuring 3D terrain, animated elements and trip narration. So, for today's #30DayMapChallenge, I decided to try creating something similar: a 3D map of Cap d'Antibes, which I recently visited in the South of France.
My interactive 3D Map of Cap dâAntibes lets you fly around the peninsula, discover some of its best-known landmarks and view the route of an incredible coastal walk. The map includes clickable points of interest, with three photographs I took on my vacation. You can also follow an animated walking route along the coastal Sentier de Tirepoil, watching the route gradually draw itself across the 3D terrain.

Soon after I posted my One Hundred Famous Views of Edo Map, Keir Clarke posted about another map of Japanese woodblock prints on his Maps Mania blog, well worth a read if you want to learn a bit about Japanese landscape art in the 19th C. It turns out that there are a lot more than Hiroshigeâs One Hundred (which are actually 119) and someone had made a map of 297 of these prints across 5 series which had lost its base map and had a couple of other glitches. Keir threw down a challenge âPerhaps Steven could take a sneak peek at the mapâs JavaScript, which contains the coordinates of all the woodblock prints featured, and use them to expand the scope of his own map.â...
The Tabula Peutingeriana is one of the most remarkable surviving maps from the ancient world. Held at the Austrian National Library in Vienna, it is a medieval copy of a Roman road map, originally drawn on a parchment scroll almost seven metres long and just 34 centimetres high.
The map depicts the road network of the Roman Empire, stretching from the British Isles and the Atlantic coast to the Middle East and India. Thousands of place names, roads and distances are recorded along its routes.
...
Visualisation is a key part of any analysis. It is useful not only at the end, when presenting the results, but also throughout the analysis itself. A quick plot can help you interpret intermediate results and decide what to do next.
R and Python offer excellent tools for creating visualisations. When working in GRASS, however, I do not always want to export or reshape the data, or have to remember, or look up, the code needed to create a simple figure. Sometimes, I just want to create a plot directly from within GRASS. At the same time, it should offer enough options to fine-tune the result for online or print publication.
...
In the 1830s, Katsushika Hokusai ignited a golden age of Japanese landscape art with his Thirty-Six Views of Mount Fuji. Capturing the topography, seasons, and human activity around Japan's sacred peak, Hokusaiâs masterpiece inspired his contemporary, Utagawa Hiroshige, to create One Hundred Famous Views of Edo - a breathtaking visual survey of Japanâs bustling capital.
Both series belong to Ukiyo-e (æ”źäžç””), "pictures of the floating world," a genre of Edo-period woodblock prints. More specifically, they elevated the sub-genre of Meisho-e (ćæç””), or "famous place pictures." Fueled by a 19th-century domestic travel boom, these prints served as both fine art and geographical guides, cataloging iconic landmarks and scenic views for a public eager to explore.
...The PostGIS Team is pleased to release PostGIS 3.7.0! Best Served with PostgreSQL 19 RC 1 , GEOS 3.15.0 , postgis_tiger_geocoder 2025.2 , and address_standardizer.
...
Doug Greenfield posted his Map of the Week â Map of the 100 Famous Views of Edo saying âThe Wikipedia listing has a table listing each print with an image, title and geographic coordinates. Somebody with more time and better programming skills could make a nice interactive map from this table with popups at each location.â
Well I have the time and an AI with some programming skills so I thought âWhy not?â
So I asked Claude:

Yesterday I visited the Night Maps exhibition at the Warburg Institute, which explores the history of celestial maps and globes, and how mapping the heavens has shaped our understanding of the world. Which might account for why I was so blown away by TripGeo Space - a brand new collection of space and sci-fi development projects.
Currently, TripGeo Space consists of two interstellar space tours:

I recently shared this map (above) showing the countries of the world as drawn by over 3,000 people playing the Borderline country border game. This combined map brings together all the borders and coastlines drawn by players in Borderline and its companion game, Coastlines.
In Borderline, players attempt to draw the outlines of individual countries on a blank map from memory. The results can be surprisingly interesting, which is why, alongside the global map above, you can also explore How the crowd draws every country.Â
This multiple-map visualization animates between each country's actual borders and a composite outline created from all the players' attempts to draw it.
...
In geospatial research and software engineering, we frequently encounter a persistent paradox: sophisticated platforms, cutting-edge hazard models, and rich spatial data infrastructures are built with tremendous technical skill and effort â but lack uptake. Why? Because the development process often occurs in isolation from the operational realities, decision-making pressures, and daily workflows of end-users.
When addressing complex crises like climate change adaptation (CCA) and disaster risk management (DRM), a purely top-down or tech-driven development approach routinely fails. Emergency responders do not need generic GIS viewers with a multitude of layers and tools; civil protection officers require clear, actionable, and rapid information products that answer specific questions during an evolving crisis.
This leads to this weekâs challenge:
...Sorry, this entry is only available in French.
Oslandia took part (actively!) in the QGIS User Conference 2026, which was held in early October in Laax, Switzerland.
The teams led four workshops and talks on the first day:
The second day provided an opportunity to attend talks and forge links with the international community!
Lately, Iâve been wondering why there's been such a dearth of interesting map styles among all the new "vibe-coded" projects floating around. My guess is that AI toolchains encourage developers to churn out projects at breakneck speed, leaving little time to jump into Maputnik and craft a bespoke style that actually complements their appâs aesthetic.
But just as I was losing hope of ever seeing another genuinely inventive style - reminiscent of the golden age of Stamen's Water Color Map or the Hand Drawn Map of Toulouse, along comes Location Scout (known in Japanese as Dokodemo Rokehan / ă©ăă§ăăă±ăăł).

North Up Daily is a new free daily map game with a simple premise. Each day, you are presented with a map of a city in which all the individual map tiles have been randomly rotated. Your task is to rotate each tile until the map is back to normal, with north pointing up.
Your score is based on how quickly you complete the map, with penalties for the number of moves and hints you use. Solve the puzzle quickly and you could find yourself on the Daily Leaderboard.

Will there be fair elections on November 3rd? I can't promise that, but Karim Douieb can promise a fair election map.
His 2026 House Forecast Map replaces the standard geographical congressional district map with one where every district is equal in size. Click the "One seat, one cell" button, and the map morphs from a 'geographic map into one where each state is resized by its seats and every district gets the same area.'
Reading the BattlefieldThe interactive map synthesizes data from the Cook Political Report, categorizing all 435 House seats according to race competitiveness ratings:
On 21 October 2026 the PHP project released fixes for two critical vulnerabilities, CVE-2026-109618 and CVE-2026-109619, now known as PHP2Shell. They allow unauthenticated remote code execution on web servers running PHP. Exploitation attempts were observed even before public disclosure. The UK NCSC has issued an alert asking organisations to find and patch every PHP installation, and to take offline what they cannot fix.
Since then we have been receiving questions from organisations running our open source products. Here is the short answer, and what we suggest you check.
Are MapStore, GeoServer and GeoNode affected?No since none of them uses PHP.

Cartographers generally agree that there are significant benefits to viewing at least five maps or globes every day. Regular map consumption can help improve your geographical awareness, strengthen your navigational muscles and provide essential nourishment for your inner explorer.
The 5 A Day campaign is based on advice from the International Geographical Union, which recommends playing at least one map game every day to lower the risk of geographical ignorance, chronic misplacement and embarrassing incidents of getting lost.
Fortunately, you don't need to swallow an entire atlas to get your daily geographical intake. Here are three nutritious map games to add to your daily cartographic diet.

As you all know by now, the php2shell vulnerability was disclosed and is wreaking havoc all across the technology landscape wherever a PHP installation is involved as everybody is frantically patching their PHP installs to mitigate this vulnerability.
Since MapGuide bundles PHP, this vulnerability sadly also affects us as well and I feel obligated to at least post something about this.
So here's the current situation of this vulnerability in the context of MapGuide.

52°North and Open Science? Nothing new here, but weâre not interested in a casual relationship. We want to make it official. Therefore, this weekâs blog post isnât about how we address a particular challenge, itâs about making a formal commitment to Open Science practices! To show our dedication, we are signing the NFDI4Earth FAIRness and Openness Commitment.
The NFDI4Earth FAIRness and Openness Commitment aims to promote the implementation of open practices and is composed of twelve items. Signing this commitment publicly signals agreement with the goals, mission, and products of NFDI4Earth.
In the following paragraphs, we will elaborate on 52°Northâs commitment to the twelve items.

London is twice as big as Colorado on the Actual Scale map.
Size comparison maps are nothing new. Youâve almost certainly used The True Size Of ... to drag the outlines of countries around a world map and compare their geographical sizes.
Actual Scale uses a similar drag-to-compare interface, but instead of geographical size, it compares population. Search for any city, state or country and drag its outline anywhere on the world map. The outline will grow or shrink to reflect the population density of the area it covers, while keeping the same total population.
In the image above, Iâve dragged London across the United States. Its boundary adjusts to encompass the same population wherever it lands. Drop London over New York, for example, and it suddenly looks a lot smaller!
...In water resources administration, the difference between reactive management and sustainable governance lies in data quality, process efficiency, territorial vision, and technological autonomy. With the launch of our new dedicated website at sirh.icarto.es, we want to highlight the main reasons why river basin authorities choose the Water Resources Information System (SIRH) by iCarto.
...Prezados leitores,
Sempre que preciso instalar uma nova instĂąncia do GeoNode, sigo os procedimentos que jĂĄ compartilhei aqui no blog:
â Instalação do GeoNode 5 no Ubuntu 24.04
â Instalação do Certificado SSL no GeoNode
â Atualizar camadas do GeoServer para o GeoNode automaticamente
O passo a passo ajuda bastante, mas, a cada instalação, lĂĄ estava eu novamente: preparando o servidor, instalando dependĂȘncias, criando o projeto, ajustando configuraçÔes e habilitando o HTTPS.

There are 89,603 registered dogs in New York City.
Dog owners are required to obtain a license for their pets, registering details including the dog's name, breed and birth year, along with the owner's ZIP code.
Every Dog in New York is an interactive map that puts this canine census on the map, revealing which breeds dominate individual neighborhoods, where particular dog names are most popular, and how the city's dog population has changed over time.
Using the map you can search for a breed, a dog's name, or a neighborhood to discover where your pooch would fit in - and where they would stand out from the crowd. The map is colored by the most common dog breed in each neighborhood.
...A student finishes a QGIS exercise, saves the project and sends the file to the instructor. The analysis is completeâbut the map is still difficult to share with a colleague, a client or the public.
That last step, taking a desktop GIS project onto the web, is increasingly part of practical GIS training. A review of publicly listed courses turns up examples around the world that include QGIS Cloud in their teaching: from publishing a first web map to working with cloud databases and web GIS.
GeoServer 2.27.7 release is now available with downloads (bin, war, windows), along with docs and extensions.

Walk Score provides address-level walkability scores, neighborhood maps, transit reports, and bike scores for virtually every city, town, and neighborhood in the U.S. and Canada. Integrated into real estate platforms such as Redfin, it is well-known and widely used across North American real estate markets. Unfortunately, its coverage outside North America is patchy.
This is why Raian Pollock decided to create Walkably.Â
Walkably maps walkability across 31 European countries, giving every street a score from 0 to 100. The scores are calculated from two factors: Reach (60% of the score) and Street Quality (40%).

Ever wondered what North America would look like if the oceans rose by a staggering 690 meters?
The Sliding Shores map gives us a fascinating peek at a radically transformed United States. Granted, even if every global ice sheet melted tomorrow, sea levels would max out around 80 meters - meaning this apocalyptic drowning is strictly theoretical. But as an exercise in extreme topographic visualization, it makes for a captivating spatial experiment.
If youâre looking to explore actual, science-backed climate projections rather than wild cartographic extremes, Climate Central's Coastal Risk Finder is probably a better sea level rise map. However, Sliding Shores does offer a more dynamic, global perspective by rendering the entire planet as a 3D interactive globe rather than as a flat 2D map.
...After writing about being laid off in April, I went almost five months without paid work. As I wrote in that post, I started with some severance. After that, I learned how to participate in Colorado's unemployment insurance benefits system. Just before reaching that program's limits, I was offered a position at Colorado State University, and I accepted. Colorado recorded 2,400 people hired in September 2026, and I was one of them.
...As I alluded to in my previous post, I've got a new job. I'm a research associate at Colorado State University, working at the Cooperative Institute for Research in the Atmosphere (CIRA). For the first time in over 20 years, I'm working for a local organization, the biggest local institution, in fact. Riding my bike to the office, learning to pack a lunch, all the things. I'm helping several research projects use satellite imagery to derive global cloud properties in near real-time.
Yesterday I attended an orientation session for new CSU employees. I've been married to a CSU professor for 21 years and already know everything there is to know about the school. Joining the employee union was a new experience. I wish there had been more of us.
There are travel blogs and then there is Three Steps Off the Coast.
For the last ten years, Sandrine and Geoffrey (now accompanied by their son Victor and pet dog) have been documenting their travels and sharing their photos, stories, itineraries, and budgets with the world on their popular travel blog. Now, to celebrate their ten-year anniversary of travel blogging, they have brought to life their 10 most memorable trips as immersive 3D travel maps.
10 Years, 10 Adventures is a collection of ten WebGL-powered animated travel maps featuring 3D terrain, animated elements, and trip narration. Instead of relying on standard mapping libraries like Mapbox or Google Maps SDKs, the project uses a bespoke WebGL rendering engine paired with custom heightmap and route data.

A few people have asked how the scoring works, and one or two have asked, a bit pointedly, why their pin 40 km from Lagos only got half marks. Hereâs the longer version of the info box: how to play, how the points add up, and where it all comes from.

The new era of building age maps has begun. Block and Paper have been busy recently creating animated building-age maps of cities around the world, showing urban development unfold over time. The style has since been emulated by others, including Parcelscope's Every Building in Los Angeles County.
Now Alexander Bogachev has imported the idea to France, creating an animated building-age map of Paris that shows when each of the French capital's 122,435 buildings was constructed.

Every day, a huge amount of spatial data is produced by public agencies, research institutes, companies, and other data providers. Spatial Data Infrastructures (SDIs) have been set up at local, national and international levels to bring these data and its metadata together and make it easier to find. Metadata standards have matured and been adopted along the way. And yet, users still struggle to find the right datasets.

Everyone knows the QGIS Plugin Repo but have you had a look at the QGIS Hub yet?
Itâs similar to the plugin repository in that it allows sharing of resources between community members, but it so many different types of resources, that warrants multiple blog posts: from styles and projects all the way to processing scripts.
Today, I want to have a look at the (a little cryptic) QLR option.
The QGIS Layer Definition (QLR) format makes it possible to share âcompleteâ QGIS layers with other QGIS users. QLR files contain links to the data sources and all the QGIS style information necessary to style the layer.

Dear Reader,
Here is a closer look at GeoNode 5.1.0, the first feature release built on top of the renewed 5.0 architecture. The release notes list everything in detail. Where GeoNode 5 was about rebuilding foundations, 5.1.0 is about putting those foundations to work. It significantly broadens the range of data GeoNode can catalogue and publish, and it tightens the controls around how that data is shared.

During a bit of football banter about League 1 over the weekend, Ken said to me âI bet youâve never been to any of those places either. All a bit far northâ â it turned out I had visited 18/24 of the places in the League. That prompted an idea for a geography quiz, could I make a quiz that combined pinning the locations of cities on a map with some general knowledge questions about those cities?
I started out with this prompt:

Laax, Switzerland, 10 October 2026. More than 420 people from over 30 countries and five continents gathered in Laax from 4 to 9 October for the QGIS User Conference 2026, the largest event ever held on Crap Sogn Gion at 2222 metres above sea level.
There are quite a few ugly buildings in my town that I'd like to demolish. Now I have the chance to actually knock them down (if only virtually) with World Strike.
World Strike is a fun new open-world, real-time multiplayer tank game where the arena is literally the entire planet - and every single building can be reduced to rubble. So if youâve ever looked at a building and thought, "This would benefit from some high-explosive ordnance," then World Strike is the browser game you've been waiting for.
From a web mapping perspective, World Strike is an impressive technical showcase of Three.js integrated directly inside MapLibre GL JS. Rather than rendering standard extruded vector tiles via MapLibre's built-in fill-extrusion layers, the developer routes OpenStreetMap footprint data into a custom Three.js WebGL layer.

Want to explore the night sky? Two new interactive maps offer very different ways to do it. Skyviewer lets you explore the vast astronomical survey being created by the new Vera C. Rubin Observatory, while Stargazing for Beginners helps you work out what you can actually see in the sky above you.
Skyviewer is an interactive window onto Rubin Observatory's survey of the cosmos. Located in Chile, Rubin will repeatedly scan the sky for the next ten years, creating an enormous time-lapse record of the changing universe. You can use Skyviewer to explore the results from these scans, navigating around Rubin's imagery to discover stars, galaxies and other celestial objects.

Ever wished you could turn your holiday GPS track into one of those slick animated maps you see in travel videos? Map Animator lets you do exactly that - and you don't need any video-editing or mapping skills to get started.
This free browser-based tool lets you draw a journey on a map or import a GPX recording and then turn it into an animated video. You can use it for road trips, motorcycle tours, cycling adventures, hikes, sailing trips and pretty much any other journey you can record with a GPS device.

FactMap is the latest map game to be a little like GeoGuessr. However instead of guessing the locations of random Street View images, in this game you need to point to the locations of five daily historical or geographical facts.
FactMap gives you a fact and asks you to work out where on Earth it happened. The answer might be the place where a famous person died, where a treaty was signed, where a band formed, or where a particular animal lives. For example, one question might ask: Where did Julius Caesar die? You then drop a pin on the map and see how close you were.
