Explore Great River, 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 Great River, 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 Great River.
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.

Great River unfolds as a quiet expanse where the brackish breath of the Atlantic Ocean drifts inland to soften the edges of the salt-marsh grasses. It lies 1.6 miles east-southeast of East Islip, NY (from East Islip, NY: bearing 117°T), and is situated 2.8 miles east-southeast of Islip. The Connetquot River carves a dark, steady vein through the landscape, its current pulling toward the horizon with a cold, insistent clarity that defines the local topography. To the north, the land rises in subtle, wooded gradients, a distant echo of the Appalachian Mountains that remain far beyond the reach of the local skyline. Near the water, the terrain yields to the low, flat silts of the coast, where the presence of Nicoll Island breaks the surface of the tidal flats. Two miles inland, the stillness of West Brook Pond offers a reflective counterpoint to the moving river, its surface a mirror for the shifting clouds that gather over the low-lying basin.
Great River retains the quiet, deliberate atmosphere of an old estate settlement, its character shaped by the vast, protected stretches of TOWN OF ISLIP Land that preserve the natural integrity of the shoreline. The local economy has long since moved past its agrarian origins, shifting into a rhythm defined by professional life and the stewardship of these sprawling, historic grounds. Residents move through the day with a sense of privacy, their lives punctuated by the seasonal migration of waterfowl and the subtle, rhythmic pull of the tides. A sense of enduring permanence permeates the neighborhood, where the architecture of earlier centuries remains sheltered by mature timber, and the pace of life seems to follow the slow, perennial cycle of the water rather than the hurried demands of the wider region.

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.
