Not much news in terms of new libraries nowadays, so just giving a little update on my own projects.
Just wrapped up a new library called PyGeoj that makes it a breeze to read and write geojson as files. By treating geojson as an actual fileformat instead of just as a set of formatting rules, the aim of PyGeoj is to make it just as easy to deal with .geojson files as with .shp files — sort of like the PyShp for Geojson data.
Earlier this summer, I started work on but not yet completed a pure-Python geometry manipulation library called Shapy. Don’t have much time to focus on it at current, so the more people test it out, give feedback, or would consider contributing to it, the better! Leave a reply or email me for more info.
