I love making open source libraries related to maps & spatial analysis.
I've written a bunch of my own libraries such as
- point-in-polygon-hao
- A very fast and reliable module for point-in-polygon checks
- sweepline-intersections
- A very fast and small module for detecting intersections between polygons and polylines
- Leaflet.SvgShapeMarkers
- Provides additional SVG markers for leafletJS
I also contribute to a range of larger projects such as
- TurfJS
- Designed and developed the documentation. Implemented various modules. Provided various bug support.
- LeafletJS
- Occassion PR's for bug fixes. Writing and contributing to various plugins.
