Explore Martin's Additions, 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 Martin's Additions, 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 Martin's Additions.
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.

Martin's Additions maintains a quiet, deliberate composure amidst the shaded, tree-lined streets that define its residential character. It lies 1.7 miles east of Bethesda, MD (from Bethesda, MD: bearing 93°T), and is situated 6.1 miles north-northwest of Washington. The landscape here is characterized by a mature canopy of hardwoods that softens the summer sun, casting long, shifting shadows across lawns that slope gently toward the path of the Pinehurst Branch. While the distant, hazy silhouette of the Appalachian Mountains remains far beyond the horizon, the local topography retains a modest, inland elevation that keeps the air crisp during the transition of seasons. Residents often find their way to the nearby Chevy Chase Park, a local public space that serves as a verdant anchor for the neighborhood, providing an open expanse where the quiet rhythm of the afternoon is punctuated only by the movement of wind through the oaks.
Martin's Additions emerged from a collection of early twentieth-century land subdivisions, evolving into a stable, incorporated enclave that prizes its independence and architectural continuity. The local economy is defined by the professional lives of its inhabitants, who contribute to the regional prosperity while preserving the domestic scale of their streets. History lingers in the understated brick facades and the proximity to the Black Horse Trail, a path that invites a slower pace of travel away from the bustle of the nearby capital. Even as the modern world presses in, the proximity to the serene waters of the Dalecarlia Reservoir three miles away and the secluded, rugged terrain of Soapstone Valley provides a sense of geographic grounding. On quiet mornings, one might catch the faint, distant suggestion of rushing water from Little Falls, a reminder of the natural drainage that shapes the broader Piedmont landscape surrounding these well-tended homes.

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.
