Images & Access The image map showing the state of includes a grid marked off in 15 minute increments. Each rectangle links to a page that lists the available images for this quadrangle. An image map exists for each New England state. In addition, there are alphabetic listings by quadrangle name and by town name for each state. For any particular date, there will most often be four images because the maps were scanned as four sections. The images are presented in this collection as JPEGs so that they may be easily viewed or downloaded.

About Historic Topographic Maps The United States Geological Survey began its topographic atlas of the United States in 1882. The UNH Library Government Information Department holds a working collection of over 55,000 paper USGS maps.
This online collection of over 1500 USGS topographic maps includes nearly complete geographical coverage of New England and New York from the 1890s to 1950s. When we began this project in the mid-1990’s, historic topographic maps were not readily available online. This collection is now complemented by maps digitized by the USGS:. Quadrangles U.S. Geological Survey maps are published in increments of longitude and latitude, which is measured in degrees, minutes and seconds. An individual 15 Minute Series map covers a rectangular area of 15 minutes.
Mar 21, 2013 - ADJOINING 7.5' QUADRANGLES...... MAC HINES RD. This map was produced to conform with the. Images & Access. The image map showing the state of New Hampshire includes a grid marked off in 15 minute increments. Each rectangle links to a page that lists the available images for this quadrangle. An image map exists for each New England state.
For example, the Concord quadrangle has a southern boundary of 43 degrees 0 minutes and a northern boundary of 43 degrees 15 minutes. This can be confusing since most other maps focus on a particular geographic feature, such as a city, state, or metropolitan area. For example, see the Manchester, New Hampshire quadrangle map. Manchester is located in the northwest corner of the map, and while most of the city is located on one map, there are parts on three other adjacent maps.
The center of Manchester is just south of 43 degrees north and just west of 71 degrees 30 minutes east. Map Scales Topographic map scales are typically expressed as ratios. A map at a scale of 1:24,000 means one inch on the map measures 24,000 inches on the ground or one inch is 2000 feet in real life.
Since the 1950s, the USGS topographic maps have been published in scales of 1:24000 and 1:25000. 1:24,000 maps of Northern New England began publication in the 1960s and have not been scanned as a part of this collection but are available from the USGS website.
7.5 Minute Series Maps, Scale 1:31680 With the exception of a few areas of Vermont, all the 7.5 minute series maps at 1:31,680 in the collection are of southern New England. Maps in this series were first published in the late 1930s and had a scale of 1:31680 until the mid 1950s.
