Explore Casas, 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 Casas, 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 Casas.
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.

Casas anchors itself to the vast, sun-drenched plains of South Texas, where the horizon stretches flat and wide under a sky that seems to press down with the weight of absolute clarity. It lies 7.0 miles northeast of Roma, TX (from Roma, TX: bearing 47°T), and is situated 9.6 miles northwest of Rio Grande City. The terrain here is defined by a hard-packed earth that holds the heat long after the sun has retreated, punctuated by the persistent, dry growth of mesquite and prickly pear. To the west, the subtle rise of Gongora Hill provides the only interruption to the infinite flatness, while the proximity of the Arroyo Garceño leaves a vein of silver-green brush across the parched landscape. Just three miles away, the expanse of Las Estrellas Preserve offers a sanctuary for native grasses and elusive wildlife, preserving a fragment of the wild country that once defined this entire region.
Casas functions as a quiet center for the surrounding ranching culture, a place where the economy remains tethered to the rhythm of the land and the seasonal demands of livestock. The influence of the nearby Falcon Reservoir shapes the regional climate, creating a subtle humidity that softens the edges of the afternoon heat and sustains the lifeblood of the nearby agricultural plots. Deep within the geography of the Arroyo los Morenos, the soil carries the memory of generations who carved a living from this stubborn, arid ground. Daily life in Casas moves with a deliberate, measured pace, reflecting a heritage built on endurance and the quiet, collective labor of families who understand that survival in this climate requires a profound respect for the scarcity of water and the resilience of the scrubland.

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.
