Open-Source Clojure Library for Geospatial Information (opens in new tab)

This is great news and I applaud the work. The state of open source for geospatial geometry has frequently been fragmented and dodgy at best so this effort to unify it are a step forward. PostGIS is the crown jewel of open source for GIS processing but a broader set of tools is much needed.

The only caveat looking at this is that the geometry computation is not suitable for some types of geospatial analytics. This has been a persistent gap in open source geospatial tools. The challenge is that closing this gap is a pretty esoteric topic in applied mathematics that only a handful of people are really qualified to address and few of them seem to be contributing to open source. Still, any progress is good.

This is excellent news. Without knowing much clojure or looking deeply into the source, I wonder if or how this project does or plans to handle projections and coordinate systems? I find this capability to be among the really important things that geospatial libraries provide.

For those that don't recognize the name on the blog post, this is aphyr, who has been publishing the excellent "call me maybe" technical posts.
