Maps Understanding

This lecture explores the history of maps, from triangulation to Geographical Information Systems, emphasizing the importance of modeling changes to organize maps as systems. It delves into the memories and innovations of maps, including the works of Eratosthenes and Snellius. The lecture discusses the measurement of the arc of the meridian, the decimal metric system, and the execution of chain triangles. It also covers vector data, GIS databases, vector and raster data, and spatial analysis techniques like triangulation and spatial indexing. The presentation concludes with a focus on coordinates, including latitude, longitude, and altitude, and the agreement on the shape of the world.
