Last week Bert Temme released ArcBruTile 0.1.6. This is a plugin for ArcGIS which uses BruTile to show tile layers in ArcGIS. This allows for an easy way to show openstreetmap data in ArcGIS which became very relevant due to it use in the Haiti crisis.
What I like so much about ArcBruTile is that it is connecting OSS to the ESRI/Microsoft world. That was one of the purposes we had in mind when creating BruTile and this is the perfect example. An added bonus is that we can now use the projection capabilities in ArcGIS on our tile layers, something that won't be possible with our C# OSS tools soon.
