Explore Riverside, 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 Riverside, 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 Riverside.
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.

Riverside occupies a verdant stretch of the Maryland Piedmont where the earth rises in slow, deliberate swells toward the distant, hazy silhouette of the Blue Ridge Mountains. It lies 2.1 miles north-northeast of Scaggsville, MD (from Scaggsville, MD: bearing 22°T), and is situated 8.9 miles south-southeast of Howard. The Middle Patuxent River carves a quiet, persistent channel through the landscape, its banks lined with dense thickets of sycamore and oak that filter the afternoon sun into fractured patterns of gold and slate. Only two miles away, the surface of Lake Elkhorn holds the sky in a mirror of still, dark water, providing a sanctuary for migratory birds and those seeking a brief reprieve from the low hum of the nearby transit corridors. The air here carries the scent of damp loam and cooling stone, a sensory reminder that Riverside remains anchored in the deep, quiet interior of the state.
Unknown Park serves as a wild, preserved perimeter just a mile away, protecting the local flora and providing a sprawling green buffer that defines the character of the neighborhood. The economy of Riverside has evolved from its early agricultural foundations into a modern mosaic of professional services and suburban commerce, yet the pace of life maintains a measured, industrious quality. Residents often find themselves caught between the momentum of the regional growth and the lingering stillness of the woods, a tension that colors the way the light fades over the rooftops at dusk. This balance between development and the preserved natural drainage of the Middle Patuxent River creates a distinct atmosphere, one where the legacy of the land remains visible beneath the modern grid of streets and thoroughfares.

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.
