The Third Dimension: Geographic Information Systems
This lecture introduces the concept of representing geographic information in three dimensions, focusing on the creation of 3D models using Geographic Information Systems. Topics covered include thematic mapping, visual variables, and the production of thematic maps. The instructor explains the importance of 3D representation for a more concrete and realistic understanding of space and object relationships. Practical aspects such as constructing 3D models using raster formats and draping vector or raster layers are also discussed. The lecture concludes with a demonstration of Qgis2threejs, a plugin for QGIS that enables the visualization of 3D landscapes in a web browser using WebGL technology.
