To import geospatial data from the shapefile (.shp format):
- Click the
button. The Open window displays
- From the Open window:
- Navigate to the directory where the file that you would like to import is located
- Select the file (.shp format)
- Double click on the file name or click the Open button
The geospatial data from the spreadsheet is appended to any existing data in the Points or Polygons table.
Shapefile Import Business Rules
To import geospatial data from a shapefile, the file must be created according to the following business rules:
- If the selected coordinate reference system at the Point and Polygon/Polyline List window is different from the coordinate reference system specified in the .prj file, the coordinate data will be re-projected to the selected coordinate system specified at the Point and Polygon/Polyline List window.
- If a PointID value is not provided in the shapefile, each coordinate data will be automatically assigned a unique PointID value.
- If a PointID is provided in the shapefile, it must be unique across all coordinate data listed in the Points table and in the Polygon/Polyline Points table on the Point and Polygon/Polyline List window.
- If the coordinate data is a point on a polygon/polyline, a unique PolyID value must be provided.
- The PolyID value must be unique across all polygons/polylines data listed in the Points table and Polygon/Polyline Points table on the Point and Polygon/Polyline List window.
