• Provide graphic map for visual verification
• It's YOUR map. Your vendor should make it available to you
• It's a FREE service

How complete and accurate your map? OGI can help. With our new independent map verification service, we can quickly check the completeness of your CAD map.  You should be able to see your map's progress, whether it is newly underway or just routine maintenance?

The map below is an initial attempt by a CAD to map a county where all parcels drawn are attributed and "joined" to the tax role. So the number of drawn and attributed parcels is the same percentage rate as the completeness percentage.
