The Map Room is a blog about maps by Jonathan Crowe. It covers everything from collecting to the latest in geospatial technology from a generalist’s perspective.
The Map Room ran from March 2003 to June 2011 and is presently inactive. Map-related links still get posted to Twitter and Facebook, and on Jonathan’s personal blog.
Between March 2003 and June 2011, I posted a total of 4,055 entries. You can explore them by visiting the archives index, or by choosing one of the monthly or category archives below:
