Global Mapper User's Manual
value has been selected on the GeoTIFF export dialog in the user interface the last used value there
will be the default.
• TARGET_COMPRESSION (ECW and JPEG2000 only) - specifies the target compression ratio to
use when creating the ECW image. The default value is 10 which strikes a good balance between
image quality and compression. The higher the value, the smaller the resulting image will be at the
expense of image quality.
• INC_VECTOR_DATA - specifies whether or not loaded vector data should be rendered and exported
to the generated image. Use a value of YES to indicate that vector data should be used. Any other
value will result in vector data NOT being saved to the file.
• FILL_GAPS - specifies that small gaps in between and within the data sets being exported will be
filled in by interpolating the surrounding data to come up with a color for the point in question. This
option is off by default, specify FILL_GAPS=YES to turn it on.
• 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 or POLYGON_CROP_USE_EACH for exceptions).
• 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 .
• ONLY_GENERATE_METADATA (GEOTIFF, JPEG, and PNG only) - specifies that only metadata
files like world files, TAB files, and PRJ files should be created for this file. This is useful for things
like generating world and TAB files from GeoTIFF files without doing a whole new export. Just
make the output filename the same as the loaded file to create the metadata for.
• COMPRESSION (GeoTIFF only)- specifies the type of compression to use for the generated TIFF
file. If you do not provide a compression value the default compression for each type will be used.
The following values are supported:
♦ NONE - Do not compress the output.
♦ LZW - Use LZW (lossless) compression on the output.
♦ JPEG - Use JPEG-in-TIFF (lossy) compression. Only works for 24-bit RGB output. Use
QUALITY parameter to set quality setting.
