Explore Sully Square, Virginia, 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 Sully Square, Virginia. 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 Virginia 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 Sully Square.
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.

Sully Square occupies a broad, unassuming expanse of the Piedmont landscape where the horizon remains defined by the distant, hazy violet silhouette of the Blue Ridge Mountains. It lies 1.6 miles northwest of Franklin Farm, VA (from Franklin Farm, VA: bearing 309°T), and is situated 5.4 miles north of Centreville. Within the verdant boundaries of Sully Highlands Park, the terrain transitions from manicured lawns to pockets of hardwood canopy, grounding the environment in a quiet, terrestrial permanence. Horsepen Run cuts a modest, winding path through the soil a mile to the west, its waters mirroring the shifting amber light of late afternoon as they move steadily across the plain. The air here holds a crisp, inland clarity, devoid of any maritime influence, carrying instead the faint, earthen scent of damp mulch and drying grass that lingers long after the sun dips below the western tree line.
Economic life in Sully Square mirrors the broader transformation of the region, where the quiet legacy of colonial-era agriculture has gradually surrendered to the pulse of a modern, technology-driven corridor. While the proximity to Dulles Airport Pond suggests a landscape defined by human utility, the area retains a deliberate, measured pace that honors its place in the history of the Old Dominion. Residents navigate a rhythm shaped by the intersection of past and present, moving between the professional demands of the local economy and the stillness offered by the nearby Conway-Robinson Memorial State Forest. Life in Sully Square reflects this duality, existing as a place where the forward momentum of the current century is tempered by the enduring, silent weight of the Virginia landscape.

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.
