Global Mapper User's Manual
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.
• 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_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.
• GRID_NAMING - specifies how to name tiles when gridding an export into multiple tiles. The value
should be SEQUENTIAL for sequential numeric naming starting at 1, SEPARATE for separate prefix
appending by row and column, or SEPARATE_COLS_FIRST for separate prefix appending by
columns and rows. For the SEPARATE options, use the GRID_NAMING_COLS and
GRID_NAMING_ROWS parameters to specify the details of how to name the rows and columns. If
no GRID_NAMING parameter is supplied, the last selected grid naming options selected in the user
interface will be used.
• GRID_NAMING_COLS - specifies how to name the column portion of grid cell names when using
the GRID_NAMING=SEPARATE or GRID_NAMING=SEPARATE_COLS_FIRST parameter. The
value of this field is a comma-delimited list with the following field values:
♦ Naming type. Can have the following values:
◊ NUM - name using numbers in ascending order
◊ NUM_REVERSE - name using numbers in descending order
◊ ALPHA - name using letters in ascending order
◊ ALPHA_REVERSE - name using letters in descending order
