The two archives available here were produced between 2016 and 2017 and provide the bases that were elaborated from existing databases, compatible with the 1: 10,000 scale, seeking the complementation of the cartographic collection available not only to the researchers of the center, but also to society through the CEM website.
The geographical conception of hydrography recognizes two basic types of phenomena on continental surfaces: watercourses (rivers, streams, channels) and bodies of water (lakes and reservoirs). In geoprocessing, water courses are usually linear phenomena, whereas water bodies are polygons (areas). The identification of hydrographic EMF files indicates this condition: HidrL (L = line), where are the rivers, and HydrA (A = area), where are the reservoirs.
