I would like to create a mask of a grid where points are evaluated as either
0's depending on if they lay outside of an irregular (i.e. not rectangular) polygon.
I have a set of high-latitude coordinates in lat/lon that define the boundary of an area I would like to make a polygon.
From this polygon I would then like to evaluate another set of lat/lon points as to whether they lay within the polygon.
Is there a library best suited for creating such a polygon (given a list of lats/lons that define it)?
shapely appears to be geared towards 2D/projected points.
What would be the best method of evaluating other points as to whether they lie within or out of this polygon?
