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.

If you click on a layer name, you can:

- make a bounding box

- create a buffer

- create a grid of squares, hexes, points, or triagles

- intersect with another polygon

- tesselate

- convert to WKT

- compare center vs weighed centroid

- view area/height/width

- split multi-polygons into their individual polygons

Other features include:

- include new polygons from a library

- create polygons from the viewport

- make random polygons

- copy layers as GeoJSON
