The topographic map of San Antonio with the highest accuracy on the internet.

Find, create and share high-resolution topographic maps using Equator.

San Antonio topographic maps, accessible in Equator, are used by infrastructure design professionals such as:

• Planners
• Architects
• Civil Engineers
• Flood Analysts
• Construction Professionals
• Landscape Designers

The Equator map will give you access to the highest quality data of any topographic map online. With the ability to get on-demand contours, point clouds, 3D surfaces and more, our users are able to make stand out maps in minutes.

The San Antonio topographic data is sourced from the United States Geological Survey (USGS), specifically their 3D Elevation Program (3DEP). You can read more about the 3DEP here. In general, built-in San Antonio elevation data is sourced from a library of airborne LiDAR surveys that are managed by the USGS, and connected to Equator for easy access.

Contours can be extracted from the San Antonio topographic map at any resolution to a shapefile (.shp) or drawing (.dxf).

Digital elevation models (DEMs), digital surface models (DSMs) and point clouds (LAZ) can also be exported.

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.

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