Explore Mercer, 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 Mercer, 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 Mercer.
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.

Mercer occupies a quiet expanse of northern Missouri, where the earth settles into a slow, deliberate cadence of prairie grass and open fields. It lies 54.5 miles west-northwest of Kirksville, MO (from Kirksville, MO: bearing 294°T), and is situated 30.2 miles north of Trenton. Collier Branch cuts a modest, winding path through the landscape, its presence marked by the silver glint of water against the deep green of wild-growing brush and the darkening soil of the surrounding plains. The air here holds a particular quality at dusk, thin and cool, carrying the scent of drying stalks and the damp, earthy reach of the lowlands. A few miles away, Lions Community Park Lake offers a still, reflective surface that mirrors the shifting violet clouds of the late afternoon, anchoring the horizon with a quiet, glassy permanence.
Mercer maintains a rhythm defined by the seasonal labor of the fields and the steady, quiet work of a population tethered to the land. The history of the area remains etched in the simple, sturdy architecture of local structures and the enduring patterns of agricultural commerce that have sustained the families here for generations. Life moves with a pragmatic, unadorned focus, far from the frantic pace of larger hubs, yet linked to the broader, plain-spoken spirit of the region. Those seeking the wider, more rugged reaches of the outdoors often find their way toward Moore-Gosch Memorial Park, where the terrain opens up, inviting a deeper connection to the woods and the quiet, persistent vitality that defines the character of Mercer.

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.
