I built this project for developers that work with geospatial data like I do. I use it to create, test, and inspect GeoJSON data and I think it might be useful for others! Let me know what you think.<p>If you click on a layer name, you can:<p>- make a bounding box<p>- create a buffer<p>- create a grid of squares, hexes, points, or triagles<p>- intersect with another polygon<p>- tesselate<p>- convert to WKT<p>- compare center vs weighed centroid<p>- view area/height/width<p>- split multi-polygons into their individual polygons<p>Other features include:<p>- include new polygons from a library<p>- create polygons from the viewport<p>- make random polygons<p>- copy layers as GeoJSON
