• Only Generate Metadata Files - causes only metadata files like world files, PRJ files, and TAB files
to be generated. This is a very handy way to create metadata files for a large collection of files like
GeoTIFF files in order to use the data in software that doesn't recognize embedded positioning
information.
• Remove Collar From Image - causes the collar of DRG-style images to be automatically removed
from each image that is converted if collar bounds can be automatically determined. Note that some
collar may remain in order to make the end result rectangular if the destination projection in not
geographic lat/lon. If you check this option and the file being converted is also loaded in the main
map view and has some custom collar cropping applied, those collar cropping options will be used
rather than the automatic DRG-style collar setting.
• Skip Existing Output Files - this option causes any conversion operations for which the default output
filename already exists to be skipped. This is useful when resuming batch conversion operations that
failed or were cancelled.
• Use Big Endian For Elevations - causes stored elevations to use the big-endian (Motorola) byte order
rather than the default little-endian (Intel) byte order.
• Use Lossless Compression - this option causes the lossless compression method to be used when
generating Global Mapper Grid files. If it is not checked, some minor loss of data in areas of high
terrain relief will be allowed in order to achieve a higher compression ratio.
• Use Other Source Files As Filler - causes all selected source files to be loaded and made available
during export to fill holes in the main file being converted. This is useful when you have a collection
of files that are being reprojected and you do not want to have a sliver around the edge of each new
file filled with the background color when the source data does not make a perfect rectangle. You can
even mark some files to only be used as filler by right clicking on them in the Files list and selecting
the appropriate option in the popup menu.
• Use Tile Layout (ADVANCED USERS ONLY) - specifies that any exported GeoTIFF files should be
organized in tiles rather than strips.
You can also right click on the list of files to convert and choose to save that list of files to a text file. This can
be a convenient way to start a Global Mapper script to do other processing on the files. Other right-click
options include the ability to remove all archive files, like .zip and .tar.gz from the list and to fill the source
files list with files listed in a text file.
Note: Only registered users of Global Mapper are able to perform batch conversions.
Combine Terrain Layers Command
Global Mapper User's Manual
The Combine Terrain Layers command allows the user to generate a new gridded elevation (or other gridded
value) layer by combining and/or comparing the elevation values from two other loaded terrain layers.
When selected, the command displays the Combine Terrain Options dialog which allows the user to set up
generation of the new terrain layer. Once completed the new terrain layer is added to the Overlay Control
Center and displayed.
