GridInterpolatorGeo2Jk Method

Convert coordinates from projection easting-northing coordinates to fractional indices in the source grid. The fractional indices can be used directly in the Interpolate(Single, Double, Double, Single) method.

For a 3 x 2 element/cell based grid, (j,k) is in the range [0;3] x [0;2].

For a 3 x 2 node based grid, (j,k) is in the range [0;2] x [0;1].
