As it can be seen it is not a choropleth map as the contours go through the states and it is not a heatmap as I do not care how many measurements underlies this. The data I have is not gridded, but I ...

This repository contains a Python implementation demonstrating a basic TERCOM (Terrain Contour Matching) approach for estimating the position of a vehicle (like a drone or missile) without GPS, by ...

Despite what you might think, I'm not a Jedi Master at python. So, here is a quick guide to contour plots and heatmaps - you can think of this as a guide for physicists.
