Explore Potomac Heights, Maryland, 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 Potomac Heights, Maryland. 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 Maryland 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 Potomac Heights.
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.

Potomac Heights occupies a quiet expanse of Maryland land where the horizon is defined by the steady, unyielding presence of the distant Appalachian Mountains. It lies 6.3 miles north-northwest of Charles, MD (from Charles, MD: bearing 341°T), and is situated 9.4 miles east-southeast of Dale City. The air here holds a distinct, earthy stillness, as if the landscape itself is exhaling after the heat of the afternoon sun has retreated into the soil. Dense, mature woodlands provide a verdant boundary for the neighborhood, leading directly into the protected grounds of Posey Gift (Met), where the undergrowth remains thick and undisturbed. Only a mile away, the dark, winding waters of Mattawoman Creek carve a slow path through the terrain, its banks lined with reeds and shadowed thickets that catch the amber light of dusk. The land maintains a modest, unassuming elevation, allowing the evening shadows to stretch long and thin across the residential streets, lending a sense of permanence to the quiet geography.
Potomac Heights evolved from post-war residential expansion, transforming from open tracts of forest into a settled neighborhood that serves as a steady pulse point for those commuting to larger urban centers. While the local economy is largely defined by this role as a residential buffer, the influence of the surrounding wilderness remains a defining feature, with residents living within reach of the quiet trails of Doncaster State Forest. The proximity to the Maiden Fair Trail offers a rare chance to traverse the regional topography, a stark contrast to the distant, bustling corridors of Hybla Valley. Life in Potomac Heights moves with a deliberate, measured pace, unburdened by the frantic rhythms of the wider world, and defined instead by the seasonal shifts in the canopy and the persistent, quiet flow of the nearby creek.

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.
