Explore Charlestown, 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 Charlestown, 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 Charlestown.
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.

Charlestown occupies a landscape of quiet, inland permanence, defined by the steady presence of rolling fields and the dense, green canopy of Elk Neck State Forest. It lies 1.5 miles west of Cecil, MD (from Cecil, MD: bearing 269°T), and is situated 8.8 miles south of Calvert. Beyond the immediate grid of Charlestown, the terrain dips toward the modest, meandering path of Hance Point Creek, a waterway that marks the land with its soft, persistent gravity. Far to the west, the faint, hazy silhouette of Rock Ridge provides a jagged limit to the horizon, grounding the wide, open sky that shifts from bruised violet to pale amber as evening settles over the local terrain. The air here holds a stillness that suggests an ancient, patient weight, far removed from the frantic pace of the wider world.
Charlestown carries a legacy rooted in early colonial planning, an intent to organize the wilderness into a structured grid that remains visible in the current layout. The local economy persists with a measured, industrious character, drawing its strength from the surrounding woods and the fertile earth that has sustained generations. Residents often find themselves passing through the public space of Charlestown, where the remnants of history are not merely preserved in books but felt in the way the wind catches the leaves of trees that have stood for centuries. Those seeking the drama of falling water might travel a short distance to witness the churn of Gilpins Falls, a reminder of the raw, kinetic energy that once powered the early mills of this region. Life in Charlestown is marked by these small, distinct landmarks, where the rhythm of the day is dictated by the slow turning of the season rather than the demands of progress.

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.
