Explore Catonsville, 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 Catonsville, 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 Catonsville.
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.

Catonsville occupies a landscape defined by the rhythmic flow of the Bill Branch, which carves its path through the terrain as a constant, quiet companion to the residents. It lies 2.1 miles northwest of Arbutus, MD (from Arbutus, MD: bearing 305°T), and is situated 6.5 miles west of Baltimore. This area maintains a subtle connection to the maritime influence of the region, sitting roughly seventeen miles from the open coastline where the air carries a faint, salt-tinged memory of the sea. Beyond the immediate canopy of trees, the distant Appalachian Mountains provide a jagged, hazy silhouette against the western horizon at dusk. Residents often find respite in the verdant spaces of Catonsville Park, a peaceful expanse that serves as a terrestrial anchor for the surrounding neighborhood. From the elevations here, one can sense the topography sloping gently toward the lower elevations near Smith Cove, five miles away, where the water mirrors the shifting colors of the sky.

Historical foundations remain visible in the architecture of older buildings, which stand as quiet witnesses to the generations that labored to shape the local economy. While the bustle of larger regional centers is never far, Catonsville retains a distinct focus on stability and sustained growth that favors long-term residents. The proximity to Sylvan Dell Valley continues to influence the layout of the land, reminding those who work and live here of the natural constraints and opportunities that defined early settlement. By cultivating a balance between professional development and the preservation of its physical character, Catonsville has secured a future that respects its past.

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.
