LA County buildings being loaded into OpenStreetMap (in 3D!)

Since we made our Building Outlines public a few years ago, I have received requests here and there for that information in order to load that information into Open StreetMap (OSM). The scope of the project is huge (over 3,o00,000 buildings) and OSM doesn’t allow, as far as I know, the ability to just […]

Thanks to Mike Carson and SoCalGIS.org for passing this along – one of the better cartography notes that I have seen about balancing features vs. labels. I highly recommend reading this if you make maps, or even if you use Google Maps!

Say goodbye to the weirdest border dispute in the world

Just found this poking around from a link sent to me – amazing what is really out there in the world. I learned about enclaves: small areas of sovereignty completely surrounded on all sides by another country – but this one is crazy:

The exchange between India and Bangladesh means that the world will not […]
