Explore Somersworth, New Hampshire, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Somersworth, New Hampshire. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of New Hampshire or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Somersworth.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Somersworth occupies a space where the Salmon Falls River serves as a vital, moving artery against the quiet backdrop of the New England interior. It lies 4.4 miles north of Dover, NH (from Dover, NH: bearing 5°T), and is situated 6.3 miles east-southeast of Rochester. The landscape rises gently toward the modest crest of Indigo Hill, providing a steady elevation that contrasts with the low-lying basin known as The Hoppers. Residents often find respite at Noble Pines Park, where the shade of mature timber offers a reprieve from the summer sun. Though the Atlantic Ocean lies fourteen miles to the southeast, the air here retains a crisp, maritime clarity that suggests the proximity of the tides. Nearby, the still surface of Lily Pond reflects the changing sky, grounding the terrain in a stillness that balances the constant, southward flow of the river.
Somersworth grew from a foundation of industrious water power, its early survival pinned to the mechanics of the textile mills that once lined the riverbank. This legacy of manufacturing shaped the local economy, fostering a resilient spirit of labor that evolved alongside the shifting demands of the industrial age. The town’s history is written in the sturdy brickwork of its older districts, where the echoes of looms have long since faded into a more diversified commercial trade. Today, the focus has shifted toward a blend of light industry and regional commerce, maintaining a steady pace that favors practical development over rapid expansion. This Yankee independence remains evident in the way the local economy adapts, leaning on the same pragmatism that once harnessed the river to drive the town’s growth.
Somersworth maintains a distinct cultural identity, marked by a history of immigrant labor that added layers of heritage to its original, rugged character. The town celebrates this diversity through local festivals that bring the quiet streets to life, offering a brief, vibrant counterpoint to the usual rhythm of daily existence. Landmarks such as the remnants of the old mill infrastructure stand as silent witnesses to the generations who carved a life out of this terrain. While the area is largely defined by its own quietude, it has been home to notable figures like the writer John Greenleaf Whittier, who spent time in the region and captured the essence of the rural landscape in his verse. Life here moves with an unpretentious grace, where the proximity to the wilderness of Blue Job Mountain State Forest invites a deep, enduring connection to the natural world.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
