Re: [gdal-dev] Does anyone have built/compiled 64 bit versions of either FWTools or gdal

Has someone already documented the performance difference between x32 and x64 versions of the FWTools / gdal? Improvement by how much? Many thanks. Kevin On Thu, Jun 3, 2010 at 1:39 AM, John Mitchell wrote: > Does anyone have built/compiled 64 bit versions of either FWTools or gdal > for: > a

Stephen, Obviously when dealing with UTM zone 1 or 60, you can expect some issues :-) The spatial extent of your source file is the following : Upper Left ( 116009.250, 276735.000) (179d32'52.82"E, 2d29'56.85"N) Lower Left ( 116009.250,-997.500) (179d33'4.57"E, 0d 0'32.43"S) Upper Rig

Panic over. I have just proven that an idiot can panic and cast suspicion on everyone but himself! The tiles seem to be reprojected OK, but Geoserver was laying the tiles on top of each other without using any transparency, hence each tile leaving a white blob on top of the last one. A quick mod

I am not sure here, but this looks like each tile is projected for itself. My procedure always is 1) Build a large image without tiles 2) Reproject 3) Create Tiles/pyramids Try to avoid TILED=YES and reproject within the same gdalwarp call. Quoting Rob : Hi [Apols for the X-post] I'm tr
