[gdal-dev] bug in OGRGeometryTypeToName

Unless there's something I'm not understanding, it seems there is a highly visible bug in OGRGeometryTypeToName() in GDAL 1.9.2. Namely, it says that all 3D types are 2D, and 2D types are 3D. See ogrgeometry.cpp: bool b25D = wkbFlatten(eType) != eType; switch( wkbFlatten(eType) ) {

Re: [gdal-dev] Which version number for the next GDAL release : 1.10 or 2.0 ?

+1 to everything Ragi said. Version "numbering" like "1.10" is an affront to common sense and the basic concept of the decimal system, not to mention every OS's filename sorting. If 1.10 comes after 1.9, then it would be imperative to replace the misleading decimal points (which are, apparently, N

[gdal-dev] Fixes for nmake.opt and makefile.vc

I needed to build GDAL on WIndows again this evening, so I grabbed the latest gdal192.zip. For years (like, 12 years) I have tried maintaining GDAL MSVC project files, but that isn't a fun task. So instead, I figured I'd give the makefile.vc a try. It does not appear to be in a state that's u

[gdal-dev] Vertical and geocentric coordinate support in OGR/PROJ4

Hi folks, The issues of geocentric CS and vertical CS are distinct, but they are related in an important way: Geocentric coordinates are not very useful to the GIS world unless they can be converted to orthometric ("sea level") heights, which involves a vertical CS. Currently, the GDAL/OGR/PRO

RE: [gdal-dev] Geocentric Coordinate System Support

Frank et al., I am testing the Geocentric support; in particular, the ability to transform from Geocentric to a SRS with a vertical datum. Since Geocentric was committed in March, and GDAL 1.8.1 was released in July, i thought that 1.8.1 might contain the Geocentric support. But, it does not see

RE: [gdal-dev] Help with GDAL & Visual Studio 2010 & netCDF

James, In this case, it may be simpler, easier and more efficient to simply call the NetCDF library directly, rather than going through GDAL. Your particular file sounds like a 3D dataset, which is stretching the bounds of what GDAL is designed to handle, namely rasters. The NetCDF API is relati

I'd add that wildfire simulation and visualization has been done on a Open stack, such as: "Application for planning assistance suppression forest fires based on free software." 2008, in Spanish. http://dugi-doc.udg.edu/bitstream/10256/1182/1/VicedoLinares_Art.pdf gvSIG, PostGIS, VTP (GDAL, OpenSc

[gdal-dev] OGR/PROJ with +geoidgrids

It is true that geocentric XYZ coordinates are not very useful, without being able to convert them to coordinate with orthometric ("geoid") ("sea level") height. Frank implemented 'preliminary' support for this, which i am preparing to test now. Before expecting it to work in GDAL/OGR, i thoug

[gdal-dev] support for libpng 1.5.0

I tried building GDAL 1.7.3 this evening and found that it did not support the new libpng 1.5.0. I also looked at the archive for GDAL 1.8.0 RC2, and it seems to have the same code in question. The changes are small, just a few like this: io
