Raed, M.A., Gari, J.M., Lorenzo, B., Sedeño, A., Antes, M., Cuello, A., and Sánchez, Y. (12-Nov-13)

Glaciares Argentina National Park is located in Andes Patagonicos and it belongs to Santa Cruz province and it limits with Chile country. It was declared Natural Patrimony of Mankind by the United Nations Educational Scientific and Cultural Organization (UNESCO) in 1981. An important part of this Park is covered by glaciers and the ice rivers give form to the landscape with abrupt hillsides mountains and wide valleys. Nowadays, the ice occupies approximately an area of 2.600 km2, with 47 major glaciers. The study areas are the Glacier Perito Moreno located over Brazo Sur that belongs to the Lago Argentino and the Glaciar Upsala located over Brazo Norte of the same lake. Besides, the environment surrounding both glaciers are taken into account to carry out a complete study of this important area. Satellite data has proved to be very important for monitoring and evaluating natural resources. The objective of using SAC-D satellite system is to compare previous researches with optical Landsat, SPOT digital data, polarimetric RADARSAT 2 with a global study given by SAC-D optical, thermical and microwave digital data. In previous papers the authors have carried out a thematic map of the natural resources of this area. In this way the different environments has been identified, characterized and the physiognomic natural forest unities described so a thematic cartography of the different identified unities are obtained.
