How to Use This Westport, South Dakota Map
This interactive map shows the street layout and satellite imagery for Westport, South Dakota. 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 South Dakota 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 Westport.
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.

ZIP code: 57481.Westport occupies a quiet stretch of the northern prairie where the horizon remains wide and uninterrupted, defined by the slow, deliberate meander of the Elm River as it carves a path through the earth. It lies 12.7 miles north of Aberdeen, SD (from Aberdeen, SD: bearing 358°T), and is situated 84.8 miles northwest of Watertown. The sky over Westport dominates the landscape, turning a bruised, deep violet as the sun sinks behind the distant silhouette of the land, casting long, thin shadows that seem to stretch toward the horizon. Six miles away, the waters of Richmond Lake provide a stillness that contrasts with the constant, subtle movement of the plains, while the nearby Willow Dam offers a refuge for local wildlife, standing as a quiet sentinel of the natural environment.
Agriculture defines the economic pulse of Westport, as the rhythm of the seasons dictates the labors of the field and the movement of heavy machinery along the rural roads. History here is written in the endurance of the soil and the legacy of families who have worked these acres for generations, finding a modest prosperity in the yield of the grain and the resilience of the local economy. The pace of life in Westport remains tethered to the land, reflecting a character forged by the extremes of the climate and the stark, honest beauty of the open plains, where the wind carries the scent of dry grass and the promise of another harvest.

About This Westport Map Page
This page provides an embedded street and satellite map of Westport, South Dakota. Coordinates: 45.648864, -98.49704. 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 Westport includes the ZIP code (57481), telephone area code (605), county seat of Brown County (Aberdeen), and school district assignment (Frederick Area School District 06-2).
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.
