Global Mapper User's Manual
♦ PACKBITS - Use Packbits (lossless) compression. Only works for 8-bit palette-based output.
♦ DEFLATE - Use Deflate/ZIP (lossless) compression on the output.
• USE_LZW (GEOTIFF only) [DEPRECATED - use COMPRESSION instead]- specifies that LZW
compression should be used for this RGB or palette-based GeoTIFF file. LZW compression typically
results in much smaller files than the default compression, but there may be some software packages
that do not yet support LZW-encoded GeoTIFF files. Specify USE_LZW=YES to enable LZW
compression.
• TILE_SIZE (GEOTIFF only) - specifies that the GeoTIFF file should be exported with a tiled
organization and use the specified tile size. This tile size should be between 8 and 2048. Typical
values are 64, 128, and 256.
• SAVE_SCALE_AND_LEGEND - specifies that the distance scale and elevation legend, if applicable
and enabled for display on the Configuration dialog, should be exported to the generated raster file.
Specify SAVE_SCALE_AND_LEGEND=YES to enable this option.
• BG_TRANSPARENT (ECW, GEOTIFF, JPEG2000 and PNG only) - specifies that any areas of no
data/background should be marked as transparent. Use BG_TRANSPARENT=YES to enable.
• OVERWRITE_EXISTING - specifies that existing files should be overwritten. The default is
OVERWRITE_EXISTING=YES, so use OVERWRITE_EXISTING=NO to skip exporting files that
already exist.
• EXPORT_SCALE - specifies the scale to do the export at. You must also specify a DPI value in order
to use the EXPORT_SCALE parameter. For example to export at 1:50,000 scale, use
EXPORT_SCALE=50000.
• DPI (GEOTIFF and JPG only or with EXPORT_SCALE parameter) - specifies the DPI (dots per
inch) value to save in the generated file(s). For example, use DPI=300 to specify that the DPI for this
file is 300. By default no DPI value will be written out.
• KML_MIN_LOD_PIXELS (KML only) - specifies how large layer has to be in pixels before it will
show up in Google Earth.
• KML_MAX_LOD_PIXELS (KML only) - specifies how large layer has to be in pixels before it will
stop showing up in Google Earth. The default value of -1 which means that a layer will never go away
once it is displayed.
• KML_FADE_EXTENT_MIN (KML only) - specifies at what number of pixels in size that the image
will start fading out. This value should be between KML_MIN_LOD_PIXELS and
KML_MAX_LOD_PIXELS. The fade will be such that the image is 100% opaque at
KML_FADE_EXTENT_MIN and completely transparent at KML_MIN_LOD_PIXELS.
• KML_FADE_EXTENT_MAX (KML only) - specifies at what number of pixels in size that the image
will start fading out. This value should be between KML_MIN_LOD_PIXELS and
KML_MAX_LOD_PIXELS. The fade will be such that the image is 100% opaque at
KML_FADE_EXTENT_MAX and completely transparent at KML_MAX_LOD_PIXELS.
• KML_RASTER_FORMAT (KML only) - specified which raster image format to use when creating
tiles for KML/KMZ files. The valid options are JPG, PNG, and TIFF. For example, add
KML_RASTER_FORMAT=JPG to use JPG format files.
• KML_SUPER_OVERLAY (KML only) - specifies that the data should be automatically gridded into
"super overlays" to allow displaying large quantities of data in Google Earth. Use
KML_SUPER_OVERLAY=YES to enable this behavior.
• KML_TILE_SIZE (KML only) - if data is being automatically gridded into "super overlays", this
specifies the size of tiles to use for gridding. The default tile size is 1024. To change this for example
to 512x512, use KML_TILE_SIZE=512.
• KML_ZOOM_SCALE_FACTOR (KML only) - if data is being automatically gridded into "super
overlays", this specifies the multiplier to use when creating zoomed out pyramid layers. The default
value of 2 makes each successive zoom level 1/2 the resolution of the previous one until everything
fits in a single tile. To change this to making each layer 1/3rd the resolution of the previous one, use
KML_ZOOM_SCALE_FACTOR=3.
