2. Digital Terrain Model. Digital Surface Model. Definition and characteristics. Methods of construction. Construction of Delaunay triangulations.
3.Extraction of profiles.
4. Map algebra, Reclassification, Proximity Analysis; Surface Analysis, Cost Surface, Resampling, Spatial Autocorrelation and Cluster Analysis.
5. Hydrological Modeling: Calculation of Flow Direction; Accumulated flow calculation; Extraction and classification of the hydrographic network; Extraction of the River Basin.
6. Spatial Interpolation: Methods and evaluation of the interpolator's accuracy.
7. Spatial analysis in Raster Systems: Development of spatial analysis models and geoprocessing tools.
8. Geographic modeling. Application cases to Territory Management.
