Global Mapper User's Manual
The additional list of options varies depending on the particular conversion being performed. The meaning of
those options is defined below:
• Add Watermark Image - when this option is checked, you will be prompted to select an image to use
as a watermark for your raster format export. You will also be allows to select display options for
your watermark image, such as transparency, to provide the desired effect. The selected watermark
image will be stretched to cover the entire output image for each converted file.
• Adjust Image Contrast - causes the contrast of any input file to be automatically adjusted prior to
being exported. This is useful for improving the display of some types of imagery.
• Clamp Export to Lat/Lon Boundary - causes the export bounds of each image being converted to be
clamped to the nearest 3.75' lat/lon boundary. This can be useful in limited cases, such as when
reprojecting to geographic/arc degrees and the source images had a tiny collar to make the image
square in the native projection.
• Convert to Grayscale - causes the exported imagery to be generated in only shades of gray.
• Crop to Selected Areas - this option specifies that each exported file will be cropped to any area
features selected with the Feature Info or Digitizer Tools. If this option is selected, no output file will
be generated for any input file that does not intersect any of the selected crop areas.
• Export Areas, Export Lines, and Export Points - these options respectively control whether area, line,
and/or point shapefiles are generated from the source vector data files. At least one of these options
must be selected.
• Fill Small Gaps in Data - this option specifies whether or not small gaps in the elevation or raster file
being exported will be filled by interpolating between nearby known values.
• Force Square Pixels in Output - causes the newly created files to have square pixels in whatever
projection they are created in. This allows the files to be used with the widest variety of other
software packages, many of which do not correctly handle non-square pixels.
• Generate Projection (PRJ) File - causes a projection file describing the ground reference system of
the output file to be generated for each output file in addition to the output file itself. The PRJ file will
have the same name as the output file with the .prj extension.
• Generate World File - causes a world file describing the location of the output file to be generated for
each output file. The world file will have the same name as the output file with the appropriate world
file extension for the output type (i.e. TFW for GeoTIFF, JGW for JPEG, etc.).
• Include Display Labels as Attributes - causes DXF attributes containing the name of the vector object
to be associated with DXF POLYLINE entities. As some software packages cannot handle attributes
in DXF files, you may have to turn this option off (with the associated loss of information) to get your
exported DXF files to work with some packages.
• Include Feature Attributes in DBF - causes the attributes other than layer and elevation of each
feature (if any) to be stored in the DBF file associated with the generated Shapefile. In addition,
selecting this option will cause the DLG-3 attribute codes matching each feature to be stored in the
DBF file.
• Include Feature Names in DBF - causes the name of each feature (if any) to be stored as a NAME
attribute in the DBF file associated with the generated Shapefile.
• Make Single Color Transparent - allows the user to select a single color to treat as transparent in the
source data files.
• Minimize Window During Conversion - this option causes the main map window to immediately be
minimized when the batch conversion operation begins and stay that way until the operation
completes.
• Never Anti-Alias Pixels (Interpolate) - this option disables anti-aliasing (interpolation) even for those
layers to which it would normally be applied by default (like gridded elevation layers) or imagery
being reprojected or resampled.
• Never Automatically Adjust Contrast - this option disables automatic contrast adjustment even for
those layers to which it would normally be applied by default (like 16-bit per color channel images).
