IMPORT
Global Mapper User's Manual
• 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.
• FILL_GAPS - specifies that small gaps in between and within the data sets being used to generate the
watershed 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.
• LAYER_DESC - specifies the name to assign to this layer. If no layer description is provided, the
default name of "GENERATED WATERSHED" will be used.
• POLYGON_CROP_FILE - specifies the full path and filename of a vector file containing a polygon
feature to which the operation should be cropped. If multiple polygons are found in the specified file
the polygon which has the largest intersection with the data to be combined will be used as the crop
polygon (see POLYGON_CROP_USE_ALL or POLYGON_CROP_USE_EACH for exceptions).
• POLYGON_CROP_NAME - specifies the name of a polygon shape previously defined using the
DEFINE_SHAPE command to which the export should be cropped. The coordinates in the shape
need to have been provided in whatever projection the new terrain layer will be in (i.e. the current
projection).
• POLYGON_CROP_USE_ALL - specifies that if a POLYGON_CROP_FILE is specified that
contains multiple polygons, the operation will be cropped to all polygons in that file rather than just
the best-fit polygon.
• POLYGON_CROP_BBOX_ONLY - specifies that if the POLYGON_CROP_USE_EACH parameter
is specified that each export should just be cropped to the bounding box of each polygon rather than
the actual boundary of the polygon. Use POLYGON_CROP_BBOX_ONLY=YES to enable only
cropping to the bounding box.
The IMPORT command imports a data file for later use. The following parameters are supported by the
command.
• FILENAME - full path to file to load the data from. This can also be the URL (http: or ftp:) for a file
on a web site that you want Global Mapper to download and load.
• TYPE - type of data file we're loading
♦ AUTO - automatically determine the type (default).
♦ ACE - Altimetry Corrected Elevation (ACE) format file.
♦ ARCASCIIGRID - Arc ASCII Grid format file.
♦ ARCBINARYGRID - Arc Binary Grid format file.
♦ AVC - Arc Vector Coverage format file.
♦ BIL - BIL format file.
♦ BSB - BSB format file (usually has .KAP extension).
♦ BT - a BT (Binary Terrain) format grid file.
♦ CANADA3D - Canada 3D format file.
♦ COMPEGPS - a CompeGPS RTE, TRK, or WPT file.
♦ CTM_DEM - a CTM DEM format file.
♦ DBF - DBase file with point features.
♦ DHM25 - a Swiss DHM terrain format file.
