Image with different coordinate system
The WMS Service that you are using has a different coordinate system than the map.
The GeoAgro GIS viewer works with Geographic coordinates and Datum WGS-1984. This WMS Service supports a different coordinate system.
Currently GeoAgro GIS does not support projected images, and for this reason it's possible that you may appreciate some displacements in the outer areas of the image. This will be solved in future versions of GeoAgro GIS.
