Global Mapper User's Manual
• FORCE_SQUARE_PIXELS - if this value is set to YES, the spatial resolution of the resultant
elevation file will be set so that the x and y pixel size are the same, with the minimum default size
being used for both.
• GLOBAL_BOUNDS - specifies the export bounds in units of the current global projection. There
should be 4 values in a comma-delimited list following the parameter name. The values should be in
order of minimum x, minimum y, maximum x, maximum y.
• GLOBAL_BOUNDS_SIZE - specifies the export bounds in units of the current global projection.
There should be 4 values in a comma-delimited list following the parameter name. The values should
be in order of minimum x, minimum y, width in x, width in y.
• LAT_LON_BOUNDS - specifies the export bounds in latitude/longitude degrees. There should be 4
values in a comma-delimited list following the parameter name. The values should be in order of
westmost longitude, southernmost latitude, easternmost longitude, northernmost latitude.
• LAYER_BOUNDS - specifies that the export should use the bounds of the loaded layer(s) with the
given filename. For example, to export to the bounds of the file "c:\test.tif", you would use
LAYER_BOUNDS="c:\test.tif". Keep in mind that the file must be currently loaded.
• LAYER_BOUNDS_EXPAND - specifies that the operation should expand the used
LAYER_BOUNDS bounding box by some amount. The amount to expand the bounding rectangle by
should be specified in the current global projection. For example, if you have a UTM/meters
projection active and want to expand the bounds retrieved from the LAYER_BOUNDS parameter by
100 meters on the left and right, and 50 meters on the top and bottom, you could use
LAYER_BOUNDS_EXPAND="100.0,50.0". You can also specify a single value to apply to all 4
sides, or supply 4 separate values in the order left,top,right,bottom.
• FORMAT (SURFERGRID only) - determines if Surfer Grid export format is ASCII, BINARY_V6, or
BINARY_V7. The default is ASCII if no format is specified.
• GEN_WORLD_FILE (GEOTIFF only) - specifies that a TIFF world file (TFW) should be generated
in addition to the TIFF file. Use GEN_WORLD_FILE=YES to turn on.
• GEN_TAB_FILE (GEOTIFF only) - specifies that a MapInfo TAB file should be generated in
addition to the GeoTIFF file. Use GEN_TAB_FILE=YES to turn on.
• GRID_TYPE_CELL_SIZE - specifies that the export should be gridded into multiple tiles with each
tile having the given size in the export projection. The value should be specified as cell width,cell
height. For example, if you are exporting in a metric projection and want to tile the export into cells
that are 10,000 meters wide by 5,000 meters tall, you would use
GRID_TYPE_CELL_SIZE="10000.0,5000.0".
• GRID_TYPE_PIXEL_SIZE - specifies that the export should be gridded into multiple tiles with each
tile having the given size in pixels/samples. The value should be specified as cell pixel width,cell pixel
height. For example, if you want to tile the export into cells that are 800 pixels wide by 600 meters
tall, you would use GRID_TYPE_PIXEL_SIZE="800,600".
• GRID_TYPE_ROWS_COLS - specifies that the export should be gridded into multiple tiles with a
given number of rows and columns of tiles. The value should be specified as number of rows,number
of columns. For example, if you want to tile the export into a grid of 8 rows each 4 tiles across, you
would use GRID_TYPE_ROWS_COLS="8,4".
• GRID_OVERLAP - specifies how much to overlap tiles when gridding an export into multiple tiles.
This is a percentage value from 0 to 100 and only applies when on of the GRID_TYPE_* parameters
is used. For example, to make your grid tiles overlap by 5% of the grid tile size, use
GRID_OVERLAP="5.0". The default value is 0.0, meaning that the tiles do not overlap.
• GRID_KEEP_CELL_SIZE - specifies that the size of the grid cells should be maintained over sample
spacing. This means that if you specify a grid of 4 rows and 5 columns, each grid cell will be exactly
25% of the total export height and 20% of the total export width. The sample spacing may be slightly
smaller than what is specified in order to achieve this. By default, the sample spacing is exactly
maintained and each grid cell may be slightly larger than specified to maintain an integer number of
exported cells. Use GRID_KEEP_CELL_SIZE=YES to enable.
