Explore St. George, 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 St. George, 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 St. George.
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.

St. George occupies a quiet stretch of land where the flat expanses of the Midwest begin to yield to the subtle, wrinkled topography of the interior. It lies 1.5 miles southeast of Affton, MO (from Affton, MO: bearing 132°T), and is situated 8.8 miles southwest of St. Louis. The local terrain is defined by low, grassy rises and the persistent, slow-moving presence of Gravois Creek, which carves a modest path through the earth nearby. Within the boundaries of St. George, the sunlight often takes on a pale, buttery quality in the late afternoon, casting elongated shadows across the lawns and public spaces that define the immediate landscape. While Oklahoma Hill rises in the distance to offer a faint anchor to the horizon, the ground here remains largely composed of fertile, unassuming soil that supports a mix of residential greenery and patches of native brush.
St. George reflects the pragmatic, industrious spirit of the region, where the economy has long been shaped by the steady rhythms of the suburban corridor and the legacy of mid-century development. The area maintains a deliberate, measured pace, far removed from the bustle of the greater metropolitan hubs that define the wider state. Residents often look toward the nearby Cement Hollow or the waters of Porter Lake when seeking a reprieve from the daily routine of work and school, finding a sense of continuity in the unchanging geography of the plains. Life in St. George remains rooted in a plain-spoken consistency, echoing the quiet persistence of the small-town threads that have long defined the character of this part of the country.

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.
