The map projection is New Hampshire State Plane, NAD83 (2011), US Survey Feet. A 10,000 foot State Plane coordinate grid is provided for reference, with coordinate lines and labels in purple. A 5000 meter UTM Zone 19 NAD27 coordinate grid is provided for reference, with coordinate lines and labels in green. Latitude and Longitude coordinates in decimal degrees are provided in the map margins for reference, with coordinate ticks and labels in black.
The magnetic declination is 15.23 degrees West, at the center of the map, as of July 2016. Based on NOAA National Geophysical Data Center's calculators at www.ngdc.noaa.gov/geomag-web/#declination, the magnetic declination is changing at a rate of 5 minutes per year, and will be 15.0 degrees West by July 2019.

This 2016 map is based on the best publicly available mapping data and resources, as well as GPS data collected and GIS map data updated by RMC volunteers. Base map features are taken in whole or in part from the U.S. Geological Survey; NH Dept. of Transportation; and GRANIT, Complex Systems Research Center at University of New Hampshire, NH's statewide GIS clearinghouse, (http://www.granit.unh.edu). High-resolution (1-foot pixel) color aerial photography acquired by NH-DOT in Spring 2015, and distributed by GRANIT, was a primary resource for 2016 map updates. The points-of-interest, trails and forest boundary features on this map are based on GIS data developed and GPS data collected by RMC volunteers.
Buildings are based on USGS 1:24,000 scale DLG data, updated in 2005 using GPS, aerial photography, and 2003 E-911 address data provided by the Town of Randolph. Buildings were updated in 2016, using 2015 aerial photography.
Peaks, Elevations, Churches, Cemeteries, Historic Sites, Springs, Waterfalls, Parking areas, Picnic areas, Tent platforms, Campgrounds, and other points of interest are based on USGS DLG data and previous editions of the RMC map. Locations were updated and new features added in 2016, using GPS and aerial photography.
Hiking Trails are based on USGS 1:24,000 scale DLG data, updated where necessary by RMC in 2003-2005 and 2016, using GPS and aerial photography. Please visit www.appalachiantrail.org and www.cohostrail.org for more information about the Appalachian Trail and Cohos Trail routes, designated on the map by "AT" and "CT" symbols.
Bike trails in Moose Brook State Park, and other Coos Cycling Club trails, are based on 2015-2016 GPS by Doug Mayer, Jim Anderson, Peter Brockett, Mike Rowell, and Scott George. For reference maps and data regarding bike trails, thanks to Coos Cycling Club and Larry Garland, Appalachian Mountain Club. Please visit http://Cooscyclingclub.wordpress.com for more information.
Hayes Copp Ski Trails (USFS) are based on 2016 GPS, using the Androscoggin Ranger District's trail map, and WMNF cross-country ski trails GIS data for reference
Snowmobile trails and corridor numbers are based on maps prepared by Waumbek Methna Snowmobile Club and New Hampshire Bureau of Trails, updated by RMC in 2016, using GPS and aerial photography, and WMNF snowmobile trails GIS data for additional reference. Please visit www.waumbekmethna.com or www.nhstateparks.org/about-us/Trails/ for more information.
Roads are based on New Hampshire Department of Transportation 2003 "Smart Roads" data, updated by RMC in 2005 and 2016, using GPS and aerial photography.
Presidential Rail Trail is based on USGS 1:24,000 scale data from GRANIT, CSRC, UNH, updated where necessary by RMC in 2005 and 2016, using aerial photography. Please visit http://friendsofthepresidentialrailtrail.org or https://www.facebook.com/groups/1710501105845142/ for more information.
Power Lines are based on USGS 1:24,000 scale data from GRANIT, CSRC, UNH, updated where necessary by RMC in 2005 and 2016, using aerial photography.
National Forest, State Park, Town Forest, and Town boundary lines are based on GRANIT data from CSRC, UNH, including conservation lands data maintained for GRANIT by SPNHF, current to April 2013. National Forest and Randolph Community Forest boundary lines were updated by RMC in 2005 and 2016, using GPS, aerial photography, deeds and survey plans recorded with the Coos County Registry of Deeds.
Streams and waterbodies are based on USGS 1:24,000 scale DLG data, updated where necessary by RMC in 2005 and 2016, using GPS and aerial photography.
Elevation contours for 50-foot intervals were developed by RMC in 2003 from the USGS National Elevation Dataset, using ArcGIS.
The tree cover overlay is based on the 2015 New Hampshire Cropland Data Layer developed by U.S. Department of Agriculture's National Agricultural Statistics Service, at 30 meter pixel resolution. The USDA classified three "crops" within the map's area of interest in Coos County: Deciduous forest, Mixed forest, and Evergreen forest, which are symbolized with 3 shades of green, darkest for Evergreen, and lightest for Deciduous. www.nass.usda.gov/Research_and_Science/Cropland/metadata/metadata_nh15.htm
