Drop a FeatureCollection and see it on a map without handing your coordinates to anyone. Validate against RFC 7946 — ring closure, coordinate order, geometry types — simplify an over-detailed shape with Douglas–Peucker so it renders on mobile, and convert to or from KML, GPX and CSV.
What this kit does that a general converter doesn't.
A map preview that runs locally. Location data is the kind you least want to paste into a stranger's server.
