Elevation Map of Ohio
This Ohio topographic elevation map shows the Buckeye State in 24 terraced elevation bands. The scale runs from 139 meters (456 ft) up to 472 meters (1,549 ft). Each band steps through the relief in sequence, so the map reads like a physical relief model. Lowlands appear in deep greens, middle elevations warm into golds and reds, and the highest terrain fades into grays and whites.
Ohio covers about 116,098 square kilometers (44,825 sq mi). The glaciers stopped partway across Ohio. As a result, the map splits between smoothed farmland in the northwest and the rugged unglaciated hills of the southeast.
Highest Point in Ohio
Campbell Hill, at 1,549 ft (472 m), is the highest point in Ohio. On this topographic map, it anchors the pale summit end of the elevation scale.
Lowest Point in Ohio
The lowest point in Ohio is the Ohio River in the southwest, at an elevation of 456 ft (139 m). On the relief map, this terrain fills the deep green base of the color scale.
Ohio Map Datasets
I prepared this relief map with elevation data from the AWS Terrain Tiles dataset. The dataset builds on the NASA Shuttle Radar Topography Mission (SRTM) along with other open topographic sources, and it serves global elevation data as map tiles that anyone can access.
The map spaces its 24 elevation bands with a blend of two methods. Half of the spacing follows equal elevation steps. The other half follows equal land area, a technique known as histogram equalization.
Why blend them?
A fixed interval scale would leave flatter regions sitting in a single color, which hides their topography. On the other hand, full histogram equalization would push a quarter of the land into summit tones. The blend lets this elevation map use the entire relief palette while the legend stays honest. Each label marks the true elevation behind its band, which is why the values are not evenly spaced.
