WebbModule 2: Geospatial Visualization using Python In this module, students will get introduced to techniques for geospatial visualization and Web mapping using Python. First we'll learn about the basics of plotting geospatial data and creating maps using Matplotlib, Basemap, and Cartopy. WebbThe Shapely Python module allows us to perform geometry operations in Python, without the need for RDBMSs (relational database management systems). That is, we do not need any software package such as QGIS or ArcGIS to perform an analysis. This is particularly useful for automation and processes that run at the server end of an application.
