By contouring, we can represent earth’s 3D landscape as a 2D map. It only takes 3 variables which are X, Y, and Z. Not only elevation data, we can create a 2D map of geospatial datasets from those 3 variables.
Most earth scientists and geographers rely on GIS to generate any kind of contouring-based map (GIS software is expensive, mostly). Contouring in Python usually requires extensive programming experience and It was an unpleasant experience for me (@_@). However I found a simple way to solve this unpleasant experience. Let’s start!
