How to Use This Allen Township, Ohio Map

This interactive map shows the street layout and satellite imagery for Allen Township, Ohio. 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 Ohio 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 Allen Township.

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.

About Allen Township, Ohio

Allen Township is a locality in Union County, Ohio, United States. It has a population of approximately 3,200. The population density is 35.0 people per km². Allen Township is located at 40.2386°N, 83.4964°W. It observes the Eastern Time (America/New_York) timezone. ZIP codes: 43040, 45843.

Allen Township spreads across a quiet expanse of fertile midwestern soil where the horizon holds a stillness born of deep, uninterrupted farmland. It lies 6.8 miles west of Marysville, OH (from Marysville, OH: bearing 271°T), and is situated 16.3 miles east-southeast of Bellefontaine. The landscape here relies on the steady, slow-moving currents of Buck Run, a waterway that serves as the quiet pulse for the surrounding fields. To the west, the elevation shifts ever so slightly toward the distant silhouette of Bald Knob, breaking the flatness of the plains with a muted, earthen gray outline. The air in Allen Township carries the scent of turned earth and drying corn stalks, a dry, honest aroma that lingers long after the sun has dipped below the trees.

Agriculture remains the primary anchor of the local economy, with heavy machinery often marking the slow passage of hours against the backdrop of vast, open skies. Residents look toward the nearby Big Darby Cr SR for a reprieve of dense, protected greenery, finding a stark contrast to the cleared rows of the surrounding crops. While the deeper depressions of Slaty Hollow provide a subtle variation in the topography ten miles out, the character of the land remains defined by the persistence of its growers and the unyielding geometry of the fence lines. Life in Allen Township moves with the deliberate pace of the seasons, tethered to the rhythms of the harvest and the simple, quiet endurance of a place that asks for little more than hard work and an observant eye.

About This Allen Township Map Page

This page provides an embedded street and satellite map of Allen Township, Ohio. Coordinates: 40.238566, -83.496357. 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 Allen Township includes the ZIP code (43040, 45843), telephone area code (614, 234, 330), county seat of Union County (Marysville), and school district assignment.

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.
