How to Use This San Carlos, Texas Map
This interactive map shows the street layout and satellite imagery for San Carlos, Texas. 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 Texas 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 San Carlos.
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 codes: 78582, 78542.San Carlos sprawls across a flat, sun-bleached expanse where the horizon draws a sharp, unrelenting line against the sky. It lies 5.7 miles east of Edinburg, TX (from Edinburg, TX: bearing 94°T), and is situated 9.8 miles northeast of Pharr. The earth here is composed of heavy, dark clay that holds the heat of the afternoon long after the sun has begun its descent, casting a copper glow over the open fields. Only three miles away, the Santa Cruz Canal slices through the brush, its presence marked by a thin ribbon of deeper green vegetation that offers a momentary respite from the relentless glare of the plains. A mile to the east, Sunflower Memorial Park serves as a quiet sanctuary where the local flora thrives in the stillness, undisturbed by the occasional dust devil that dances across the road.
San Carlos maintains a pace dictated by the seasonal cycles of the land and the steady, industrious rhythm of agriculture. The economy remains rooted in the soil, with wide tracts of farmland surrounding the residential outskirts and defining the daily life of those who work the rows. History here is quiet, etched into the modest architecture and the long, straight stretches of road that connect neighbors to one another. Life in San Carlos carries the weight of a frontier heritage, where the distance to features like Delta Lake 1 or the distant Sunrise Hill provides a sense of scale to the vast, open country. Residents find a particular beauty in the clarity of the evening light, which transforms the dusty plains into a palette of violet and gold, grounding the spirit in a landscape that demands both patience and resilience.

About This San Carlos Map Page
This page provides an embedded street and satellite map of San Carlos, Texas. Coordinates: 26.295668, -98.063057. 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 San Carlos includes the ZIP code (78582, 78542), telephone area code (830), county seat of Hidalgo County (Edinburg), and school district assignment (Edinburg Consolidated Independent School District).
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.
