Karnes County, Texas Map

Reading the Karnes County map

The outline on this map is Karnes County's legal boundary as published in the U.S. Census Bureau's TIGER/Line files. At 750 square miles, the county is roughly the size of a square 27 miles on each side — small enough to cross in a short drive. Straight survey lines on the map usually mark boundaries drawn by the legislature, while winding edges follow rivers and creeks.

The red marker shows Karnes City, 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.
