Open Topo Data

Open Topo Data: Open-Source US Topographic Map Dataset

Open-source topographic map dataset covering the entire United States, providing detailed terrain and landcover information for mapping and geospatial analysis.

What is Open Topo Data?

Open Topo Data is a free, open-source topographic map dataset that covers the entire continental United States. It is developed and maintained by volunteers with the goal of providing high-quality topographic data for public use.

The dataset includes detailed vector-based mapping data such as contours, hydrography, landcover, transportation, boundaries, structures, and more. The data uses USGS topographic map standards and symbology for consistency and interoperability.

Some key features and uses of Open Topo Data include:

• Enables mapping and geospatial analysis with accurate, up-to-date terrain information
• Compatible with major GIS software for easy integration into projects and workflows
• Support for high-resolution printing and image rendering
• Base data for 3D visualization and land modeling
• Outdoor recreation planning, land management, and scientific study

The project is open source so the dataset can be freely used, modified, and redistributed. Community contributions help improve coverage and detail across the country.
