Explore Henry, 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 Henry, 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 Henry.
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.

Henry anchors itself firmly against the slow, deliberate curve of the Illinois River, where the water reflects the expansive, shifting sky of the Midwestern plains. It lies 27.1 miles west of Streator, IL (from Streator, IL: bearing 269°T), and is situated 19.0 miles southwest of Peru. Beyond the riverbanks, the terrain stretches out in a patchwork of fertile soil and quiet woodlands, with Whitney Lake resting in the nearby landscape to catch the evening light. Central Park serves as the green, communal core of Henry, providing a quiet space where the air often carries the scent of damp earth and the distant, rhythmic hum of agricultural machinery. The horizon remains wide and unobstructed, defined by the steady, horizontal lines of the prairie that seem to pull the eye toward the distant rise of Owls Head.
Development in Henry owes its character to the river’s long-standing role as a corridor for trade and transit, shaping an economy that remains deeply rooted in the productivity of the surrounding fields. Brick storefronts line the streets, reflecting a period of steady growth that turned this riverside settlement into a hub for the farmers of the region. Life here moves in accordance with the seasonal cycles of corn and soybean harvests, a cadence that has persisted for generations. While the nearby Rattlesnake Hollow suggests the wilder, uneven terrain of the deeper interior, the immediate surroundings of Henry offer a more tempered, hardworking beauty, where the permanence of the architecture meets the seasonal transition of the landscape.

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.
