Explore Oglesby, 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 Oglesby, 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 Oglesby.
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.

Oglesby anchors itself firmly upon the rugged bluffs where the Vermilion River carves a deep, winding path through the limestone strata of the Illinois landscape. It lies 11.8 miles west-southwest of Ottawa, IL (from Ottawa, IL: bearing 253°T), and is situated 4.2 miles east-southeast of Peru. The air here holds the scent of damp earth and crushed stone, a physical weight that anchors the horizon to the sprawling, golden-green plains that stretch toward the distant silhouette of High Ridge. Within the immediate orbit of the town, the terrain drops away into the shadowed depths of Saint Louis Canyon, where the light filters through the canopy in thin, pale ribbons. Only two miles distant, the waters of Split Rock Lake remain quiet and still, reflecting the expansive Midwestern sky that shifts from a bruised violet to a stark, clear gray as the sun descends behind the grain elevators.
Oglesby maintains a character forged in the grit of industrial labor and the steady pulse of the regional economy, having long defined itself by the extraction and refinement of the earth beneath its feet. Unknown Park serves as the green lung of the locality, providing a quiet expanse where the remnants of a working-class history are softened by the encroachment of wild, native grasses. The rhythm of daily life moves with the deliberate pace of a place that understands the value of a hard day’s work, moving between the heavy silence of the limestone quarries and the steady, familiar commerce of the main thoroughfares. Here, the legacy of the nineteenth-century industrial expansion remains etched into the architecture, a collection of brick and stone buildings that stand as modest, durable sentinels against the changing seasons.

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.
