Explore Martinez, 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 Martinez, 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 Martinez.
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.

Martinez unfolds across a landscape of sun-bleached grasses and stubborn scrub oak, where the earth holds the heat of the day long after the shadows lengthen. It lies 6.9 miles east-southeast of Fort Sam Houston, TX (from Fort Sam Houston, TX: bearing 111°T), and is situated 9.5 miles east of San Antonio. Chupaderas Creek carves a winding, intermittent path through the local terrain, its dry bed a testament to the cycles of rain and drought that define this inland reach. Three miles distant, the still surface of Soil Conservation Service Site 3 Reservoir mirrors the vast, cloud-streaked sky, offering a quiet reprieve from the relentless dry air. On the horizon, the distant ridges of the Edwards Plateau shimmer in the haze like a faded watercolor, a reminder of the rugged limestone country that lies far beyond the immediate horizon.
Martinez maintains a steady, deliberate pace, rooted in a history of agriculture and the quiet persistence of those who worked the soil before the modern sprawl arrived. The local economy persists through a blend of small-scale enterprise and the slow, rhythmic labor of maintaining the surrounding plains, far removed from the frantic commerce of the major corridors. Neighbors often find their way to the shaded benches of Schaefer Library Park, a modest stretch of green that serves as the social anchor for the local population. Here, the character of the land is measured not in grand monuments, but in the way the light catches the dust on a summer evening and the enduring resilience of a community that has quietly carved its own place into the Texan expanse.

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.
