How to Use This St. Augustine, Illinois Map

This interactive map shows the street layout and satellite imagery for St. Augustine, 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 St. Augustine.

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. Augustine emerges from the vast, flat expanse of the Illinois prairie as a quiet congregation of structures defined by the relentless horizon of corn and soybean fields. It lies 16.0 miles south of Galesburg, IL (from Galesburg, IL: bearing 187°T), and is situated 6.0 miles south of Abingdon. The landscape here is defined by an insistent flatness, where the sky claims the majority of the visual field, shifting from a pale, bleached blue at midday to a bruised, heavy violet as the sun dips behind the distant silhouette of Haney Hill. Only a mile away, the sluggish, earthen path of Cedar Creek cuts through the silt, providing a subtle, meandering break in the monotony of the fields, while the quiet stillness of Paul Lake awaits two miles to the west, its surface often mirroring the drift of high, thin clouds. The air carries a scent of turned earth and drying husks, a dry, pervasive fragrance that anchors the senses to the rhythmic, seasonal cycle of the Midwest.

St. Augustine maintains the stoic character of a place built upon the labor of the soil, its history inextricably tied to the expansion of rail and the subsequent cultivation of the surrounding acreage. The economy remains tethered to the productivity of the land, with the architecture reflecting a utilitarian, no-nonsense aesthetic of brick and timber that has weathered through decades of harsh, biting winters and humid, stifling summers. A few miles to the north, the protected grounds of Avondale Lake provide a rare, managed refuge from the geometric precision of the surrounding farms, offering a sanctuary of wilder growth amidst the orderly rows of crops. Life in St. Augustine moves with a measured, deliberate pace, dictated more by the grain elevator’s intake and the turning of the seasons than by the frantic pulse of the distant, grid-locked cities to the northeast.

About This St. Augustine Map Page

This page provides an embedded street and satellite map of St. Augustine, Illinois. Coordinates: 40.718373, -90.410962. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for St. Augustine includes the ZIP code (61474), telephone area code (815), county seat of Knox County (Galesburg), and school district assignment (Abingdon-Avon Community Unit School District 276).

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.
