Background
Topographic data for Ohio
Topographic data in Ohio is produced by the United States Geological Survey, the Ohio Geological Survey, and county geographic information system offices. Using contour lines to represent elevation and landforms, these datasets cover areas such as the Appalachian Plateau, the Till Plains, and the Lake Erie coastal plain. Programs like the Ohio Lidar Initiative and mapping projects from the Ohio Department of Natural Resources provide elevation data used by civil engineers, environmental planners, urban planners, and hazard analysts.
These datasets support flood modeling, infrastructure design, and watershed management. Equator improves this workflow by offering three dimensional terrain visualization, combining multiple datasets, analyzing slope and drainage, and facilitating collaboration across teams.

What is the source of Ohio's topographic data?
Most official topographic data for Ohio is produced and maintained by the U.S. Geological Survey (USGS) through the 3D Elevation Program (3DEP). This program uses high‑resolution LiDAR and other elevation sources to generate accurate contour lines, DEMs, and surface models. Some local agencies also contribute updated LiDAR and elevation data to supplement USGS coverage.
