Coordinates and Projection Systems

This lecture covers the geometric description of territory modeling, focusing on scales, coordinate systems, and projection systems. It explains the relationship between scale and spatial resolution, the process of transposing the geoid to a flat surface, and the different types of projections used in cartography. The lecture also introduces the WGS84 system, locally adjusted ellipsoids, and the three main projection families: cylindrical, conical, and azimuthal. Additionally, it discusses ellipsoids of revolution, projection systems as legal positioning references, and the EPSG code for system description. For further exploration of these topics, the instructor recommends the 'Elements of Geomatics' MOOC.
