Explore Derwood, 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 Derwood, 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 Derwood.
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.

Derwood marks the transition where the suburban sprawl of the Piedmont begins to yield to the quiet, persistent pulse of the earth. It lies 2.1 miles south-southwest of Redland, MD (from Redland, MD: bearing 205°T), and is situated 5.0 miles east-southeast of Montgomery. The landscape is defined by the steady, modest flow of Crabbs Branch, which carves a narrow path through the terrain, its waters reflecting the pale, shifting light of an overcast afternoon. Derwood Station Np provides a localized anchor of green, a space where the dense canopy thins to reveal the raw, unadorned character of the soil. To the distant west, the silhouette of the Blue Ridge Mountains creates a jagged charcoal line against the sky, while the cooling air carries the scent of damp leaves and turning seasons, suggesting an atmosphere that remains indifferent to the haste of the modern commuter.
Historical traces in Derwood linger in the quiet architecture and the deliberate layout of its older corridors, standing as silent witnesses to a time when agrarian rhythms dictated the pace of life. While the local economy has largely shifted toward the professional demands of the surrounding region, the remnants of a more deliberate, land-based existence persist in the spacing of the homes and the preservation of open commons. Residents often look toward Lake Bernard Frank for a sense of stillness, finding in its quiet surface a mirror for the contemplative nature of the surroundings. Those seeking a longer path through the landscape might journey toward the Paw Paw Passage Trail, where the physical history of the region is mapped out in dirt and gravel, far removed from the sharp edges of the commercial centers that lie ten miles toward the depth of Mather Gorge.

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.
