Background
Topographic data for New Hampshire
Topographic data in New Hampshire is collected by the United States Geological Survey, the New Hampshire Geological Survey, and municipal geographic information system offices. With contour lines to represent elevation and landforms, these datasets capture regions such as the White Mountains, the Lakes Region, and the Merrimack Valley. Programs including the New Hampshire Lidar Initiative and mapping efforts from the New Hampshire Department of Environmental Services supply elevation data used by civil engineers, environmental planners, hazard analysts, and land use officials.
These datasets guide flood risk evaluation, watershed management, and infrastructure planning. Equator strengthens this work by allowing users to visualize terrain in three dimensions, integrate datasets, evaluate slope and drainage, and coordinate insights across teams.

What is the source of New Hampshire's topographic data?
Most official topographic data for New Hampshire 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.
