Explore Markham, 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 Markham, 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 Markham.
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.

Markham rises from the flat, sprawling expanse of the Texas plains, a place where the horizon stretches wide and unencumbered under a sky that seems to hold more light than the earth below. It lies 6.0 miles west-southwest of Bay City, TX (from Bay City, TX: bearing 255°T), and is situated 19.7 miles north-northeast of Palacios. The land here is defined by a deep, quiet persistence, characterized by heavy soils that have supported agriculture for generations and thickets of brush that mark the boundaries of working cattle ranches. To the north, the slow, muddy progress of Wilson Creek winds through the brush, providing a vital artery for the local flora, while the stillness of Jennings Lake offers a reflective pause in the terrain just a few miles away. The air carries the scent of sun-warmed grass and dry earth, a pervasive clarity that sharpens the edges of every fence line and silo as the sun begins its long, amber descent.
Markham retains the steady, deliberate pulse of a locality built on the foundations of rail transit and the industrious spirit of the inland agricultural economy. The legacy of the early settlement remains evident in the modest architecture and the straightforward layout of the streets, which navigate the quiet commerce of a region deeply tied to the land and the oil patch. Residents find recreation in the managed green spaces of Le Tulle Park, where the shade of mature trees provides a reprieve from the intense midday heat that defines the seasonal cycle. Life in Markham follows the rhythm of the harvest and the routine of the ranch, maintaining a character that values neighborly self-reliance and a quiet observation of the changing seasons over the frantic pace of the outside world.

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.
