Today Chile has no elevation model (DEM) with national character. Analyzed from the point of view of science and geomatics technologies, a DEM and the orthoimages may be updated in their respective scales 1:25,000 and 1:50,000, these are essential for national development in its various applications. Due to new developments in hardware and software technology it is possible to lead towards new methods of processing and have access to satellite technology to create cartography with new parameters and elements. Based on the methodology employed by Imagine Spot for the generation of cartographic products, the proposal of this research are modifications to methodology to develop our means and get a DEM with the respective orthoimagen, which will validate the data both vertically and horizontally, thus to generate maps for the different productive and strategic areas of the country. From the results obtained it can be concluded that the proposed methodology meets all the objectives and opens a new opportunity to innovate in developing quality cartographic products.
