Convert Coordinates from Grid to Latitude/LongitudeLance A. Waller
This functions transforms a set of coordinates in regular lon/lat degrees, grid_in = [lon, lat], to a set of coordinates in rotated lon/lat degrees, grid_out = [lon', lat'], and vice versa:[grid_out] = rotated_grid_transform(grid_in, option, SP_coor)...
To set the grid, use thesetGrid(grid)method on the map view. Relevant API Grid LatitudeLongitudeGrid LineSymbol MapView MgrsGrid SimpleLineSymbol TextSymbol UsngGrid UtmGrid Tags coordinates, degrees, graticule, grid, latitude, longitude, MGRS, minutes, seconds, USNG, UTM ...
This gives us the 7-digit numeric only values. The Convert class has a method to convert this to Lat/Long values. Note that this will be in the Airy Datum (also known as OSGB Lat/Long) and a further ellipsoid conversion will be necessary if comparing to GPS coordinates. ...

A location on the icosahedron can be mapped to the sphere, as in the following example of the coordinate (20.3, 12.5) on face 2:ISEAProjection projection = new ISEAProjection(); GeoCoordinates c = projection.icosahedronToSphere(new FaceCoordinates(2, 20.3, 12.5)); c.getLat(); // ...
