Re: [OpenMap Users] determining if a lat/lon point is over land or over water

You might be able to use an a Shape file representing land masses (i.e. dcwpo-browse) and test if the location is contain in a polygon. The accuracy near shorlines would be definitely be an issue.

Othewise, you will need a terrain database with feature data against which you can query.

Does OpenMap provide any support for determining if a
specific lat/lon geospatial coordinate is over land or over water?
