To import geospatial data from the shapefile (.shp format):

  1. Click the Import Points button. The Open window displays
    PointandPolyListWindow.png
  2. From the Open window:
    1. Navigate to the directory where the file that you would like to import is located
    2. Select the file (.shp format)
    3. 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.

Note.jpg EditReportIcon.png Import Points button imports both point and polygon shapefiles. Point shapefile will be imported into Points table, Polygon and Polyline shapefiles - into Polygon and Polyline Points table.
Note.jpg 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.
Note.jpg The used decimal symbol in the shape file must be the same as the Regional settings of the importing computer.

To import geospatial data from a point shapefile, the file must be created according to the following business rules:

  1. A PointID value is a mandatory field and should be provided for each point and be unique across all coordinate data listed in the Points table. It should be of Short Integer type.
  2. A PointType is a mandatory field and should be provided for each point. It must correspond to the Geospatial Point types list defined by IMSMA. The field should have Text type.

To import geospatial data from a polygon shapefile, the file must be created according to the following business rules:

  1. The Polygon attribute table must contain field called PolyID of Short Integer type and have a value e.g. 0 or 1.
  2. Coordinate Format, Coordinate System, Bearing, Distance, Point ID, Point Number, Point Type, X/Long, Y/Lat are optional to be included into the attribute table.
