Global Mapper User's Manual
• 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
♦ Starting value for numbering or lettering (i.e. '1', or 'A').
♦ Prefix string to use before the numeric or alphabetic value.
♦ Step value for numeric naming (default is '1')
You can leave values blank if they don't apply or you want to use the default. As an example, to do
numeric naming starting at the number 100, increasing by 10 each time with a prefix of DEM, you
would use GRID_NAMING_COLS="NUM,100,DEM,10".
• GRID_NAMING_ROWS - specifies how to name the row portion of grid cell names when using the
GRID_NAMING=SEPARATE parameter. See the documentation for the GRID_NAMING_COLS
parameter above for details on the format.
• GRID_NAMING_PREPEND_ZEROES - specifies whether or not to prepend zeroes to the start of
grid column/row names. Use GRID_NAMING_PREPEND_ZEROES=NO to disable the prepending
of zeroes.
• GRID_NAMING_SEPARATOR - specifies the separator string to use between pieces of a grid name.
The default is an underscore.
• GRID_CREATE_FOLDERS - specifies that a separate folder should be generated for each row (or
column if GRID_NAMING=SEPARATE_COLS_FIRST is specified) of the export rather than
placing every output file in the same folder.
• QUAD_NAME (USGS_DEM only) - specifies the quad name to place in the header of the USGS
DEM file.
• FILL_GAPS - specifies that small gaps in between and within the data sets being exported will be
filled in by interpolating the surrounding data to come up with an elevation for the point in question.
This option is on by default, specify FILL_GAPS=NO to turn off.
• VERT_EXAG (VRML only) - specifies the vertical exaggeration to use when creating the VRML file.
Larger values result in a rougher terrain being generated while smaller values result in a smoother
terrain. A value of 1.0 results in no vertical exaggeration at all (i.e. a nearly true to life
representation). If you don't specify a value the currently selected vertical exaggeration value on the
Vertical Options tab of the Configuation dialog will be used.
• COORD_DELIM (XYZ_GRID only) - specifies the delimeter between coordinates
♦ COMMA - coordinates are separated by commas
♦ FIXED_WIDTH - coordinates are stored in fixed width columns
♦ SEMICOLON - coordinates are separated by semicolons
♦ SPACE - coordinates are separated by space characters
♦ TAB - coordinates are separated by tab characters
• BYTES_PER_SAMPLE (BIL, ERDAS, and GEOTIFF only) - specifies how many bytes to use per
elevation sample in the BIL, IMG, or vertical GeoTIFF file. Valid values are 2 bytes (16-bits) and 4
bytes (32-bits). If this value isn't specified, 2 bytes are used.
