How can I turn a massive number of coordinates into a boundary or polygon?

Question

I've got a large number of points that, when plotted individually, make for huge KML files. I would like to create a boundary for these points rather than plotting them individually. I am using python and a package called simplekml.

Answer 1

Instead of having tomany points, you can put all those coordinates to form lines or polygons. For doing lines see the example from the simplekml Linestring tutorial. You can also learn from the MultiGeometry tutorial. Depending on the resolution that you need, you can also try to decimate your data with python before passing it to kml.
