   12     </methodID>
   13     <remarks>Method for use by a Coordinate Conversion defining a 2D GridCRS in a 2D baseCRS, based on CV_RectifiedGrid in ISO 19123 so the grid can be rotated and skewed in this baseCRS. </remarks>
   14     <methodFormula>The reverse direction (from the grid CRS to the baseCRS) shall be as specified by the equations:
   15     BaseX = origin(1) + offsets(1,1) * GridX + offsets(1,2) * GridY
   16     BaseY = origin(2) + offsets(2,1) * GridX + offsets(2,2) * GridY
   17 where 
   18     GridX, GridY are position coordinates in the grid 2D CRS
   19     BaseX, BaseY are position coordinates in the 2D base CRS
   20     origin(1), origin(2) are the two coordinates of the grid origin position in the 2D base CRS
   21     offsets(1,1), offsets(1,2) are the grid point offsets of the first grid axis in the 2D base CRS
   22     offsets(2,1), offsets(2,2) are the grid point offsets of the second grid axis in the 2D base CRS
   23 
   24 The forward direction (from the baseCRS to the GridCRS) equations are not included here. </methodFormula>

This wcs:Offsets shall contain four values, the first two values shall specify the grid offset for the first grid axis, and the second pair of values shall specify the grid offset for the second grid axis. </remarks>
