Connecticut, Rhode Island, Massachusetts, New Hampshire and Vermont join the more than 43 states covered by the US Topo.
To keep pace with the growing demand for the latest map coverage of the United States, the U.S. Geological Survey (USGS) has been building a national map series named the US Topo. Nearly 690 revised digital maps covering Connecticut, Rhode Island, Massachusetts, New Hampshire and Vermont have been added to approximately 51,000 maps currently covering the lower 48 states and are available for free download from the website.
"Whether you are a New England resident looking for the bird's eye view of the contours of your environment or an outdoor enthusiast seeking to explore the Northeast's stunning countryside and mountain landscape, the availability of these new maps is terrific news," said USGS Director Marcia McNutt. "Not only are they easily downloaded from the convenience of your home computer, but at 'free', the price is right!"
New feature additions and improvements on the updated US Topo maps include:
US Topos are derived from key layers of geographic data found in The National Map which delivers visible content such as high resolution aerial photography, which was not available on older paper-based topographic maps. The US Topo also provides modern technical advantages over the original lithographic map as it supports wider and faster public distribution and enables on-screen geographic analysis for users.
Future enhancements to the US Topo are scheduled to include additional functional capabilities and content, such as a shaded relief layer, Public Land Survey System (PLSS) data, updated structures, enhanced transportation, additional federal boundaries, and Forest Service trails. The USGS expects to produce more than 18,500 revised quadrangles annually, which means each US Topo map is updated every three years in a cyclic fashion.
The new digital electronic topographic maps for these New England states– along with 43 other completed states - are now available for free download from the USGS Store. The quadrangles are delivered in GeoPDF format and may be viewed using Adobe Reader software, also available as a no cost download.
