Explore Alton, Texas, 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 Alton, 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 Alton.
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.

Alton occupies a vast, sun-drenched expanse of the Rio Grande Valley where the horizon stretches flat and wide under an unrelenting sky. It lies 4.0 miles northeast of La Homa, TX (from La Homa, TX: bearing 50°T), and is situated 7.8 miles northwest of McAllen. The landscape surrounding Alton consists of fertile, level plains that have long been shaped by intensive agriculture and the steady, rhythmic labor of those who work the soil. To the north, the terrain remains largely open, characterized by the subtle, arid beauty of brushland that seems to hold the heat of the day long after the sun has dipped below the plains. Residents often find quiet moments of respite at Silvya Vela Park, a local space that provides a necessary green reprieve amidst the expansive, sun-baked grid of the regional development. While the distant silhouette of Sunrise Hill marks the horizon twenty-four miles away, the immediate geography remains defined by the deliberate, man-made lines of irrigation that sustain the local flora.
Growth in Alton reflects a history deeply tied to the expansion of trade and the agricultural prosperity of the surrounding region. The local economy draws much of its vitality from the industrious flow of goods and services that move across the nearby international border, fueling a steady development of commercial and residential sectors. Historically, the area transitioned from raw, scrub-covered land into productive acreage, providing a foundation for the businesses that now organize the daily life of the population. While the Edinburg Main Canal serves as a vital artery for the region, its presence underscores the importance of water management in sustaining both the industry and the modest, hardworking character of the local economy. Alton continues to evolve as a corridor for commerce, balancing the quiet persistence of its agricultural roots with the modern demands of a growing, connected population.
Cultural life in Alton thrives on a vibrant, bilingual heritage that informs everything from the local cuisine to the spirited nature of public gatherings. Traditions here are kept alive through community events that emphasize family and the shared experiences of a population rooted in both Mexican and American customs. For those seeking active recreation, the Schupp Park Trail offers a path for residents to engage with the environment, covering six miles of the surrounding landscape. While the region is not defined by famous figures in the national spotlight, the spirit of Alton is carried by the everyday people who contribute to the distinct, hardworking identity of the valley. Life here moves with a steady, pragmatic pace, where the warm light of the late afternoon serves as a constant, golden reminder of the resilience and history ingrained in the very dust of the plains.

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.
