• Construction Professionals

What is possible with the topographic map?

The Washington, D.C. topographic map can be used in Equator to:

• View 3D surfaces from built-in LiDAR
• Generate contours
• Source and view LiDAR point clouds
• Cut cross sections on the fly
• Extract elevation data
• Create markups, labels and figures
• Link share data

Where does the topographic data come from?

The data is sourced from the United States Geological Survey’s 3D Elevation Program.

You can read more about the 3DEP here .

The built-in elevation data in Equator is sourced from a library of airborne LiDAR surveys.

Can I extract contours?

Contours can be extracted from the topographic map at the resolution of your choosing. Contours can be exported to a variety of formats including shapefile (.shp) and drawing (.dxf). Digital elevation models (DEMs) are also available.

How do I bring contours into Civil 3D?

Contours can be opened in AutoDesk Civil3D (or similar) simply by opening an dxf file or shapefile exported from Equator. This tutorial explains how to create a 3D surface in Civil 3D directly from a shapefile.

Why should I use Equator to access Washington, D.C. Topography?

Equator allows users to access local LiDAR surveys to the best available resolution.  Experience 3D topography in high-resolution, unlike ever before.
