Explore Unionville, New York, 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 Unionville, New York. 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 York 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 Unionville.
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.

Unionville emerges from the flat, expansive terrain of the northern plains, defined primarily by the slow, deliberate movement of the Raquette River as it carves a path through the earth. It lies 3.1 miles north-northwest of Potsdam, NY (from Potsdam, NY: bearing 346°T), and is situated 6.1 miles south of Norfolk. The air here holds a crisp, northern clarity, thinning slightly as the horizon stretches toward the distant, hazy silhouette of the Adirondack Mountains. Within the boundaries of the Town of Potsdam Land, the landscape remains largely unadorned, characterized by wide stretches of fertile soil and groves that transition into the dense, shadowed timber of the Saint Lawrence State Forest Number 23. Light at dusk often settles heavily upon the fields, turning the sky a muted, bruised violet that reflects off the quiet, dark surface of the river.
History in Unionville is etched into the grid of its roads and the sturdy, unpretentious architecture of its oldest structures, which speak to a heritage built on the labor of the land. The local economy persists in a steady, rhythmic alignment with the seasons, favoring agriculture and the careful management of regional timber over the frenetic pace of larger centers. While the roar of Allen Falls remains a distant, powerful memory for those who travel eight miles to reach it, the daily life of Unionville is defined instead by the proximity of localized industry and the quietude of the surrounding woods. Residents move with a deliberate purpose, finding a particular gravity in the stillness that defines the region, far from the influence of the sprawling urban corridors that dominate the southern reaches of the state.

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.
