Adding Length and Area fields

Length and Area fields are automatically populated fields that display length of the line feature or area of the polygon feature. Values in those can’t be edited as they are automatically generated.

Values displayed in the data grid use units of the map. If the projection uses meters, the values displayed in data grid will also be in meters. If the projection of the map uses degrees, the numbers in the columns will also show degrees units. Map Projection can be checked in Map Properties, Under Advanced tab.

Area and length units can’t be changed unless the layer is reprojected to the projection with desired units. Please note that Area/Length columns have to be removed from layer (Layer Properties – Attributes tab – Edit layer) and added again in order to display the new units.

Note: layer has to be imported into Database. Only layers added to a map from Database can be edited and display area and length.

To add Length column:

  1. Select a database line layer.
  2. Go under the Layer Properties – Attributes tab.
  3. Click Edit attributes button.
  4. From the drop down menu select Length field.



  6. Click Add button, Close and Save.
  7. To see changes in the Data Grid:

  8. Go under Layer Properties and under Display tab click Recache button.
  9. Click Save.
  10. Click Refresh Data Grid button.

To add Area column select a database polygon layer and repeat steps above. Select Area from the drop down menu.
