This is to improve viewing in GlobalMapper of generated files:

It is possible to create tiled TIFFS (ie 32,64,128,256,512 pixels x*y) - however the files created with GlobalMapper are untiled. This will greatly improve the viewing of several files.

For more information:
GTiff -- GeoTIFF File Format - It is possible to view these files in GlobalMapper so it should be possible to create them aswell since they will improve loading a lot

Not sure if this tiling is official for geotiff?

Also - add support for adding overviews of the files - as this will also help a lot on viewing.

    The tiling is official for GeoTIFF, it's just not yet supported as a possible export option in Global Mapper. It is on the todo list though, as is overview export.

    Thanks,

    The latest version appears to support exporting internal tiles for geotiff but does it support overviews yet? Is it possible to script internal tiles or overviews when exporting to geotiff?

    Thanks,
    Chad

    Chad,

    There is not currently any support for creating overviews for export GeoTIFF files.

    You can specify a tile organization for an exported GeoTIFF by using the TILE_SIZE parameter in a script. For example, to create 256x256 pixel tiles, add the TILE_SIZE=256 parameter to the EXPORT_RASTER or EXPORT_ELEVATION script command.

    Let me know if I can be of further assistance.

    Thanks,
