With the image processing system and GIS capabilities, together with the Institutional Linkage Programmme Project (McGill and KKU), Khon Kaen University could establish a spatial land and water database of the Northeast both regional and detailed scaies. These data include aoil types, rainfall isohytes,terrain, water and forest resources with and objective of supporting the natural resource development plans in the Northeast. More than 120 map sheet of spatial land and water resource database have been complete. Directly linked to this is research into the application of remote sensing and GIS to integrated mapping, temporal land cover change, and modelling of petential soil salinity. The result obtained can help supports the sustainable development plan of natural resources in the Northeast.
