Explore Grantwood, Missouri, 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 Grantwood, Missouri. 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 Missouri 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 Grantwood.
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.

Grantwood reveals itself through the steady, rhythmic passage of Gravois Creek, which slices through the landscape with a quiet, persistent energy that defines the local topography. Beyond the immediate banks of the creek, the land rises into the persistent, earthen swells of the Missouri interior, a terrain marked by the heavy, loamy soil of the plains and the encroaching influence of the distant Crescent Hills that blur the horizon in shades of bruised violet and slate. The air here holds a particular weight, especially as the sun wanes, casting a long, amber glow that settles into the hollows and illuminates the dusty gold of the late-season grasses. While the deeper reaches of the state offer grander elevations, Grantwood maintains a modest, grounded presence, anchored by the dense, deciduous woodlands that turn to copper and ochre long before the first frost arrives.
Grantwood carries the quiet marks of a legacy that favored steady cultivation and the patient expansion of the suburban frontier. The local economy and daily rhythm find a persistent pulse in the presence of Grant's Trail, a corridor of movement that serves as a modern artery for residents who traverse the path where the pace of the afternoon slows to the speed of a bicycle or a steady walk. This space acts as a vital intersection of history and recreation, effectively replacing the older, industrial quietude with the hum of a contemporary, neighborhood-centered life. Despite the relative proximity to the regional sprawl, the atmosphere remains defined by the persistent, plain-spoken character of the Midwest, where the memory of earlier agrarian roots lingers in the architecture and the deliberate, unhurried way the residents navigate their chores under the vast, open canopy of the Missouri sky.

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.
