Converting closed polylines to polygons (Defense Mapping)

Once Multinational Geospatial Co-production Program (MGCP) cells have been validated using the MGCP LandCover Validation tool, you can create polygons from the closed polylines that are found by the tool. The tool converts the closed polylines features that have been recorded in the Reviewer table to polygons based on the template selected. This allows the LandCover features to create a continuous base with no gaps.
