If the Use LZW Compression option is checked the image data will be compressed using the LZW compression algorithm This generally results in the best compression for TIFF files but is not yet supported by all software applications If the application s that you are going to be using the TIFF file with supports LZW using this compression method is definitely suggested If the Generate PRJ File option is checked a describing the projection of the coordinates in the file will automatically be created If the Make Background Void Pixels Transparent option is checked for 24 bit RGB or JPEG in TIFF files an alpha channel will be added to the created GeoTIFF file to indicate which pixels should be treated as transparent Note that this will create a larger file and not all applications will support TIFF files with alpha channels Export Global Mapper Grid Command The Export Global Mapper Grid command allows the user to export any loaded elevation grid data sets to a Global Mapper Grid format file The Global Mapper Grid format is a highly compressed elevation grid format that loads and draws very quickly and requires very little memory If you have a choice for what format to store your gridded elevation data in we suggest using the Global Mapper Grid format When selected the command displays the Global Mapper Grid Export Options dialog which allows the user to setup the export The dialog consists of a General options panel which allows the use
