To clarify what Martin is referring to: I have created two additional TerraGear preprocessing tools, namely a GDAL-based chopper for DEM data and an OGR-based vector data decoder. However, I'd like to test them some more before submitting the patches, specifically as the GDAL-chopper still introduces some artifacts in the scenery which I'm currently tracking down. The GDAL-based DEM-chopper can read all GDAL-supported raster formats. This was necessary as we want to use preprocessed SRTM-data from http://srtm.csi.cgiar.org/ which is available as GeoTIFF only. The possibility to use any other GDAL-supported formats is merely a nice by-product as I didn't want to write another GeoTIFF-reader and using an external GeoTIFF-only-library when GDAL is available was somehow pointless. The OGR-based decoder was inspired by Martin to ease processing for the case when we will be building scenery on the same machine/network where also the landcover/terrain database will reside. We can then directly process the vector data from the database to TerraGear chopped polygons and avoid the intermediate step via shapefiles. As a nice by-product the OGR-decoder opens up a huge set of input formats without additional work being required. At some point we might even want to drop the specific shape- and TGVPF-decoders to reduce maintenance effort. The patches are already in the SVN-trunk of fgfs-builder: http://svn.qmx-systems.com/fgfsbuilder/trunk I'll try to keep them current while I'm continuously fixing stuff. > To my knowledge the intention is to let LinuxTag take place at this > year's location, the "Berlin Expo Center under the Funkturm" for > several years to follow. Well, in that case, we have the chance to have our Berlin scenery grow and getting improved step by step every year. ;-) Cheers, Ralf ------------------------------------------------------------------------- Take Surveys.
