ILWIS 3.6

    * Inclusion of GDAL in much the same way as Geogateway once was included. Non ILWIS raster data can be used natively in ILWIS. This is a big step forward with respect to the previous support of GDAL.
    * Postgres tables and Postgis point and segment maps can be accessed natively from a Postgis database. A first implementation has ben made to access these sources of data. It will be further extended in the future
    * User interface for Import has been improved to support a plug-in model for imports
    * Imports now largely follow a plug-in model(some old ones excepted). New imports can be added without changing ILWIS
    * The plug in model has been extended to cover plug ins stored in zip files that need their own folder structure to organize their functionality
    * Surface energy balancing (SEBS) has been extended and improved.
    * Number of bug fixes
    * Improved installation program

Objet : [Ilwis] ILWIS 37 Beta

I have placed in the download area of 52N ( http://52north.org/index.php?option=com … p;catid=35) a beta version of the ILWIS 3.7. This isn't the final product and I have no doubt there are still a number of issues with it ( still weeding out the bugs).
New functionality :

Applications:
PointMapUnion
PointMapIntersect
PointMapSymetricDifference
PointMapDifference
PointMapRelate
SegmentMapVoronoi
SegmentMapTin
SegmentMapUnion
SegmentMapIntersect
SegmentMapSymetricDifference
SegmenMapDifference
SegmentMapRelate
PolygonMapBuffer
PolygonMapConvexHull
PolygonMapUnion
PolygonMapIntersect
PolygonMapSymetricDifference
PolygonMapDifference
PolygonMapRelate

-The SEBS module and the HydrologicalFlow module are updated and for SEBS help is included in seperate help files.
-WMS has been slightly improved ( UI and error handling).
-Postgres database access works now as intended.
-A number of bugs have been removed and I still am removing more

A few things have been shifted to the 3.7.1. Mainly revamping the help system so I did not include yet help information about these new applications as that has to wait until I have made the help system easier to extend.

If people find bugs, and I am mainly interested in bugs with regards to the vector system, please mail me. Put in the subject header ILWIS BUG so I can easily put them in a seperate folder. Bug reports in the nature of "XXX doesnt work" will often be discared by me as the report has to be a bit more specific.

In the past ILWIS had limited 3D capabilities. One could make a GeoRef3D which generated a 3D image (with a DTM) but it was cumbersome to use and quite slow. One of the goals of the 3.8 was upgrading these capabilities to something usefull.
In line with the design goals as mentioned in a previous blog, the idea was to create a 3D enviroment that could be helpfull for visual analysis. When one looks at a rendering of a map (2D), basically you explore the relations between the spatial locations and one or more attributes that are related to that spatial location. The most used is of course some color representing the value of an attribute. There are several schemes to enhance this ( number of attributea) in 2D but they often become a bit confusing.
