The Image Format section allows the user to select the format of the image to generate. Different formats
have their own unique strenghts and weaknesses which make choosing the best format vary depending on the
desired end results. The supported formats are:
• JPEG - JPEG is a lossy format that achieves excellent compression on images with a lot of color
variation, such as pictures of real world objects and shaded elevation data.
• PNG (Portable Network Graphic) - PNG is a lossless format that achieves excellent compression on
images without a lot of color variation, such as line (vector) drawings and paper map scans such as
DRGs. The generated PNG file will be of the 24-bit variety.
• (Geo)TIFF - TIFF is a lossless format that is supported by many GIS packages. Saving the screen to a
TIFF with this command generated a 24-bit uncompressed TIFF. In addition, all georeferencing data
is stored in a GeoTIFF header attached to the TIFF, making the image completely self-describing.
• Windows Bitmap (BMP) - BMP is a widely support format on Windows platforms. Saving the screen
to a BMP results in a 24-bit uncompressed image.
The width and height of the generated image in pixels are specified in the Image Size panel. By default, the
size of the Global Mapper view pane are used. Using these values will generate an image that exactly matches
what you see. You can change these values to generate a more or less resolute image with the obvious tradeoff
of size vs. quality.
Checking the Generate World File option results in a world file being generated in addition to the image. The
world file will be generated in the same directory as the image and will have the same primary name as the
image. The filename extension will depend on the selected image type (JPEG=.jpgw, PNG=.pngw,
TIFF=.tfw,BMP=.bmpw).
Checking the Generate Projection (PRJ) File option results in a projection file being generated describing the
ground reference system of the created image. The projection file will be generated in the same directory as
the image and will have the same primary name as the image with an extension of .prj.
Checking the Generate Text Metadata File option results in a text file being generated listing the metadata for
the captured image.
Checking the Crop to Loaded Map Data option results in a text file being generated that is cropped to the
bounds of your currently loaded map data rather than the full screen extents. If the loaded map data does not
take up at least the entire screen then your specified pixel dimensions will also be shrunk so that the pixel size
remains the same.
Pressing the OK button prompts the user to select the name and location of the image to generate and then
proceeds to generate the image.
Note: Only registered users of Global Mapper are able capture the screen to an image file.
Export Global Mapper Package File Command
Global Mapper User's Manual
The Export Global Mapper Package File command allows the user to export any or all of the loaded data to a
Global Mapper package file. These files are similar to workspace files except that the actual data is stored in
the files. Package files provide an easy way to pass around lots of data between Global Mapper users on
different computers with a single self-contained file.
When selected, the command displays the Global Mapper Package Export Options dialog which allows the
user to setup the package export. The dialog consists of a Package Options panel, a Simplification panel, a
