Explore Tennessee, Illinois, 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 Tennessee, Illinois. 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 Illinois 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 Tennessee.
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.

Tennessee emerges from the undulating expanse of the Illinois prairie as a quiet confluence of fertile soil and wide, open sky. It lies 9.4 miles west-southwest of Macomb, IL (from Macomb, IL: bearing 250°T), and is situated 15.6 miles east of Carthage. The landscape shifts gradually from the flat, industrious fields that define the regional horizon to the more sequestered hollows where the East Fork La Moine River carves a deliberate path through the earth. Only a few miles away, the quiet basin of Rattlesnake Den Hollow creates a sanctuary for local flora, while the proximity of Irish Lake offers a still, reflective surface that mirrors the shifting intensity of the Midwestern light. On clear days, the distant silhouette of Gin Ridge provides a faint, elevated boundary to the landscape, grounding the view in a geography that feels ancient and unhurried.
Agriculture remains the primary pulse of Tennessee, where the seasonal rhythm of planting and harvest dictates the tempo of daily life. The legacy of those who first settled these plains persists in the sturdy, utilitarian architecture of the region and the enduring commitment to the land. Residents find recreation and respite at Argyle Lake State Park, a nearby space that preserves the rugged character of the terrain, while the Cut Off Trail invites those who wish to traverse the woods on foot. Life here moves with a steady, pragmatic grace, defined by the seasonal color of corn and soybean stalks and the quiet persistence of a community that has found its balance in the vast, inland geography of the heartland.

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.
