If they are in the USGS DRG standard format, they should tile properly. At least the 1:24k ones, which are the format the code was optimized for. > When you say the Xastir code is written to handle lines, do you mean > scanlines are strips as defined in the tiff/geotiff spec? Yes. If you look around the USGS DRG site you can find details of their standard format. They have a limited number of colors and are arranged in strips. The unmodifed maps are in UTM projection and have a white border. The Xastir code will strip off this border as it displays and stretch the map into unprojected or lat/lon projection. -- Curt, WE7U. archer at eskimo dot com http://www.eskimo.com/~archer Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.
