Validating a LandCover feature

When the LandCover area within a cell is validated, a feature class is created so gaps in the LandCover can be represented in the map. The gaps are captured as line features and can include holes within a ground feature that is inside the cell. The MGCP LandCover Validation tool validates the LandCover feature within a cell feature during a Reviewer session and writes any errors found to the Reviewer table. Information written to the table consists of gaps found in the LandCover area contained within a cell.

Remarque :

The validation tool can only be used with a single cell.

Since the MGCP specification does not allow gaps within the LandCover area, these gaps must be filled using a feature class that is permissible to use as LandCover area.
