Reading the Harris County map

The outline on this map is Harris County's legal boundary as published in the U.S. Census Bureau's TIGER/Line files. At 1,729 square miles, the county is roughly the size of a square 42 miles on each side — large enough that crossing it by car can take well over an hour. Texas county lines are a mix of surveyed straight lines and natural features — compare the edges of this map to see which ones follow water.

The red marker shows Houston, the county seat, and the highlighted shapes in the schematic view are the bordering counties. Use the layer switcher to change between street, satellite and terrain backgrounds: satellite is best for seeing farmland and development patterns, while terrain shows hills, valleys and river corridors.
