Explore Union, New Jersey, 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 Union, New Jersey. 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 Jersey 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 Union.
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.

Union defines itself through a landscape of persistent, inland industry where the Spruce Run flows directly past the local terrain, carving a path through the earth that dictates the rhythm of the surrounding acreage. It lies 7.1 miles north of Hunterdon, NJ (from Hunterdon, NJ: bearing 356°T), and is situated 6.8 miles south-southeast of Washington. The air here holds a heavy, settled quality, shifting as the light wanes over the distant Fox Hill Range, which anchors the horizon nine miles away. Beyond the immediate reach of the Spruce Run Reservoir, the ground rises into subtle, firm elevations that break the monotony of the plains. During the twilight hours, the atmosphere thickens with a cool, grounded stillness, casting long, sharp shadows across the fields that stretch toward the boundaries of Long Valley.
Union maintains a character forged by a history of industrious migration and the quiet persistence of its residents. The local economy thrives on a blend of service, commerce, and the enduring legacy of suburban development that characterizes this part of the state. Life here centers around the daily movement of people navigating the intersections of tradition and modern growth, often finding recreation in the Spruce Run Recreation Area, where the water provides a constant, quiet backdrop to the bustle of the day. The influence of past generations remains visible in the architecture and the deliberate layout of the streets, ensuring that the identity of Union is marked by a steady, pragmatic grace rather than the fleeting trends of the outside 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.
