The MAPIMPORT procedure
enables you to import Esri shapefiles (spatial data formats) and process
the SHP files into
SAS/GRAPH traditional map data sets.
See for more information.
The MAPIMPORT procedure
does not produce any graphics output. Instead, it produces an output
map data set, which can be used with the GMAP procedure.
The shapefiles file types are described
in the following table:
Shapefiles File Types
|
|
|
Identification information
(field-identifier names and values) assigned to specific polygons
|
|
Shape information for
the polygons that compose the map.
|
|
Combines the shape information
for the polygons that compose the map and the identification information
(field-identifier names and values) assigned to the specific polygons
|
Note: If you import a very highly
detailed map, then the GMAP procedure might produce extraneous lines
when drawing it. To avoid this issue, use the GREDUCE procedure to
reduce the number of map points.
