Explore Dover, 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 Dover, 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 Dover.
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.

Dover reveals itself through the steady, patient movement of the Cocheco River as it carves a path through the landscape toward the distant pull of the Atlantic Ocean. It lies 4.4 miles south of Somersworth, NH (from Somersworth, NH: bearing 185°T), and is situated 9.0 miles southeast of Rochester. The air here holds the crisp, salt-tinged promise of the tides, even though the open shore remains thirteen miles away, leaving the terrain to settle into a quiet, terrestrial rhythm. To the west, the land rises briefly at Garrison Hill, offering a vantage point over a region defined by granite outcrops and the soft, verdant expanse of the Mallego Plains. Residents often find solace in the stillness of Immigrants Park, a green sanctuary that anchors the local geography, while the nearby Sunken Island adds a touch of mystery to the surrounding waters.
Dover traces its origins to the early seventeenth century, emerging as one of the oldest permanent settlements in the region through the hard-won persistence of those who arrived to harness the power of the waterways. The early decades were marked by the demands of a frontier existence, where the necessity of survival shaped a character defined by Yankee independence and a pragmatic approach to the surrounding wilderness. Over the generations, the settlement transitioned from a cluster of colonial outposts into a resilient hub of industry, maintaining a deep respect for the foundations laid by those who first cleared the timber and organized the initial trade routes. This historical continuity remains visible in the architecture that lines the older streets, reminding observers of a time when the labor of the hands dictated the prosperity of the entire community.
Dover serves as a vital economic center where the legacy of manufacturing has gracefully shifted toward modern enterprise, education, and professional services. The infrastructure reflects a town that has successfully balanced the preservation of its heritage with the needs of a contemporary workforce, drawing strength from the proximity of institutions like the University of New Hampshire nearby. Local commerce hums with a productive energy that moves along the transit corridors, supported by a diverse array of businesses that capitalize on the regional connectivity. Even as the town grows, the underlying spirit of self-reliance persists, ensuring that the local economy remains as durable as the stone foundations that have anchored its buildings for centuries.
Dover cultivates a distinct cultural identity, marked by annual festivals that bring neighbors together in the streets to celebrate the changing seasons and the communal spirit. While the town does not house professional sports teams of its own, the local affinity for collegiate athletics is palpable, reflecting a broader regional passion for competition and team loyalty. Landmarks such as the historic mills offer a tangible connection to the past, standing as silent witnesses to the passage of time against the backdrop of a sky that often turns a brilliant, cooling gray at dusk. Though famous figures are few, the true character of the place resides in the everyday lives of its people, who find contentment in the simple beauty of a stroll toward Lily Pond or a quiet afternoon spent within the canopy of Smith State Forest.

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.
