I'm trying to produce a tile matrix set from geocoded tiffs using gdal2tiles.py but I am having trouble with the last step in the process.
As an example I have a BSB file from NOAA which is a navigational map of Lake Pend Oreille in Idaho. The map has a SRS of WGS84 and a Mercator projection. I initially translate the file from BSB format to GTiff format using the following command: > gdal_translate -of GTiff noaa\18554_1.kap noaa.tif I can view this GTiff file using Paint Shop Pro quite fine. I then translate the file from GTiff format to VRT format using the following command: > gdal_translate -of vrt -expand rgba noaa\noaa.tif noaa\noaa.vrt I then try to generate a tile matrix set using the following command: > gdal2tiles.py noaa\noaa.vrt noaa But get the follwoing error: > ERROR 1: failed to load NAD27-83 correction file > ERROR 1: GDALSuggestedWarpOutput() failed because the passed > transformer failed. > usage: Usage: gdal2tiles.py [options] input_file(s) [output] > > gdal2tiles.py: error: Size of the pixel in the output differ for X and Y axes. Am I missing something? My system is Windows Vista (32-bit). I'm using GDAL v1.6.0 win32 binary, GDAL v1.6.0 python package, PROJ4 v4.4.6 win32 binary, NumPy v1.2.1 for win32 and Python v2.4.1 I have set all the appropriate system variables and copied files to approprate locations. This was done following the guidelinse at http://www.gis.usu.edu/~chrisg/python/2009/docs/gdal_win.pdf except that I omitted steps 3f and 3g. Hope you can help. Brett
