Boston GIS and Historical Maps from the David Rumsey Collection

David Rumsey Collection announces the addition of 18 historical maps of the Boston area from 1776 through 1897 for viewing in its GIS Browser -- available online at www.davidrumsey.com.  The GIS Browser allows integration and interaction of historical maps with current geospatial data and other historical maps.  Additional historic maps of U.S. cities will be added in the near future including Washington, New York, Los Angeles, Chicago, Denver, and Seattle.

The current geospatial data that can be overlaid and compared to the historical maps includes roads, lakes, parks, state boundaries, digital orthophotos (aerial photography), topographic mapsheets, digital elevation  models and satellite imagery.  The GIS Browser is available in two versions on the site, a GIS Basic Browser for those new to GIS and a GIS Professional Browser for those familiar with GIS conventions.
