Global Mapper User's Manual
• USE_BIG_ENDIAN (BIL only) - specifies that elevation values written to BIL files should use big
endian (Motorola byte order) rather than the default little endian (Intel byte order).
• USE_ESRI_HDR (BIL only) - specifies that the ESRI .hdr format should be used for the export. Use
USE_ESRI_HDR=YES to enable.
• POLYGON_CROP_FILE - specifies the full path and filename of a vector file containing a polygon
feature to which the export should be cropped. If multiple polygons are found in the specified file the
polygon which has the largest intersection with the data to be exported will be used as the crop
polygon (see POLYGON_CROP_USE_ALL for exception).
• POLYGON_CROP_NAME - specifies the name of a polygon shape previously defined using the
DEFINE_SHAPE command to which the export should be cropped. The coordinates in the shape
need to have been provided in whatever projection the export is being done in.
• POLYGON_CROP_USE_ALL - specifies that if a POLYGON_CROP_FILE is specified that
contains multiple polygons, the export will be cropped to all polygons in that file rather than just the
best-fit polygon.
• POLYGON_CROP_USE_EACH - specifies that if a POLYGON_CROP_FILE is specified that
contains multiple polygons, the operation will generate a separate export for each polygons in that file
rather than just the best-fit polygon. See the POLYGON_CROP_BBOX_ONLY and
POLYGON_CROP_NAME_ATTR options for naming and other options when using this parameter.
Use POLYGON_CROP_USE_EACH=YES to enable.
• POLYGON_CROP_BBOX_ONLY - specifies that if the POLYGON_CROP_USE_EACH parameter
is specified that each export should just be cropped to the bounding box of each polygon rather than
the actual boundary of the polygon. Use POLYGON_CROP_BBOX_ONLY=YES to enable only
cropping to the bounding box.
• POLYGON_CROP_NAME_ATTR - used to control the filenames generated when cropping to
multiple polygons using the POLYGON_CROP_USE_EACH parameter. This should be the actual
name of the attribute from the polygon features to use for naming, or the special values or . If no value is provided, the exported files will be sequentially
numbered.
• POLYGON_CROP_FOLDER_ATTR - used to control the filenames generated when cropping to
multiple polygons using the POLYGON_CROP_USE_EACH parameter. This should be the actual
name of the attribute from the polygon features to use as a folder name before the actual filename or
the special values .
• ALLOW_LOSSY (GLOBAL_MAPPER_GRID only) - specifies whether or not a slight loss in
precision is allowable in order to achieve better compression ratios. The default is YES, so turn only
use lossless compression you need to specify a value of ALLOW_LOSSY=NO.
• EXPORT_COLORS (XYZ_GRID only) - specifies that RGB color values should be exported for each
coordinate that is saved.
• 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.
• ADD_OVERVIEW_LAYERS (ERDAS only) - specifies that overview (pyramid) layers should be
generated for the export. Use ADD_OVERVIEW_LAYERS=YES to enable.
• BLOCK_SIZE (ERDAS only) - specifies the block size to use for the export. The default is
BLOCK_SIZE=64.
• COMPRESS_OUTPUT (ERDAS only) - specifies whether or not the exported file should be
compress. The default is COMPRESS_OUTPUT=YES.
• 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.
• DISABLE_BIGTIFF (GEOTIFF only) - use to disable the automatic creation of BigTIFF-format files
for very large exports. Use DISABLE_BIGTIFF=YES to disable the automatic BigTIFF support.
