This has worked First of all obtain the software to convert mrsid to geotiff from the Lizardtech site.
follow the complete instructions here http://www.paulnorman.ca/blog/2011/03/converting-mrsid-to-geotiff/ (some commands are different if using Debian, particularly the PATH commands) With that Geotiff convert to appropriate datum (help required here from the expert) "gdalwarp: gdal command to convert from one datum and projection to another" " -s_srs is source datum and projection using the EPSG codes. Code 28355 is GDA94, MGA zone 55" "The maps are actually in WGS84, UTM Zone 55, but it's only a 2 or 3 metre difference and I knew where to find the GDA codes" gdalwarp -s_srs EPSG:28355 -t_srs EPSG:4326 8130s.tif 8130s_lat.tif Then those files had "3 samples per pixel instead of 1" and this is attended to by rgb2pct.py 8130s_lat.tif /usr/share/xastir/maps/tif/8130s_lat.tif copying it into the xastir directory as I went. final result here http://www.flickr.com/photos/36563247@N07/8002767769/in/photostream _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
