I'm working on a problem where in one part, I have to define 'hotspots' which are circles/spheres around a central point, and in the other, I have to identify if a specific (user-defined) point lies within any of these hotspots.
Problem 1: According to this question, the standard does not contain the definition of a circle using GeoJSON. The accepted answer to the question references a library, but written in JS. Do we have the equivalent or an alternative way to define a sphere/circle in Python? (3.x would be nice, but i'm willing to port if not.)
Problem 2: This question answers a scenario where I can find if my user's location is within any defined polygons. The question is, can I use $centerSphere in any way to define the polygon in question? If not, then what are my alternatives?
