Polished 1790 carat Diamond

May 2 2010

Virginia is attached!  Need we say more?  We’d like to think that this is the most accurate and complete topographical map of the District of Columbia in 1790 that exists.

It’s interesting to note that this map represents decades of work by the historical cartographer Donald Hawkins, years of work by Peter Chirico’s USGS group, and ten months for GIS Specialist, Lindsay Schroader, at the Imaging Research Center, UMBC.

Dan Bailey and Lindsay Schroader have prepared an article that presents the entire technical and scholarly process of creating the map.  You can download an electronic PDF copy: Visualizing Early Washington DC. This article appears in the The Portolan, journal of the Washington Map Society, Issue 80-Spring 2011, pages 33-41.
