Geotable models are used to get variable values by point location. The geotable models operate in a grid spanning the geodetic coordinate space (latitude, longitude).
For Finland there are models in the prediction model library to convert cartographic (northing, easting) point locations into geodetic coordinates.
Geotable inputs and outputs are defined in the XML interface (for example, see (Geo table)). The actual geotables can be constructed, for example, with the scripts found in http://svn.simo-project.org/tools/trunk/txt2latlon
