TOPO! Data Sets
Integrate seamless, USGS 1:24,000-scale (7.5') maps into your project with TOPO! State Series datasets. These are the most detailed topographic maps available - optimized for viewing and printing so you get the most accurate, photo-quality maps.

TOPO! Data Sets are widely regarded as the best available. We scanned every USGS Quadrangle (over 58,000 of them), color corrected each one, and developed a seamless data set that spans all 50 states. The underlying DEM information is compiled at 1 Arc-second, or 30 meters. This provides you with a consistent data set that can be used for multiple topographic purposes. Use the hillshading feature to emphasize changes in elevation. Adjust the shading intensity for your preference or turn it off altogether to view the original USGS maps. Your data set is also edge-matched, making it easy to do large mosaics, without the hassles of removing collars or text. USGS data sets are the standard in topographic information, and we are pleased to provide them to you in single-state or multiple state sets.
TOPO! Pro Data Sets Feature :
- The gold standard in base maps: Most map-minded people are familiar with USGS topographic maps. They provide a trusted and pleasing backdrop for any project, including your ArcGIS projects.
- Access to complete U.S. coverage, packaged by state or region: State Series data sets are sold on CD-ROMs. Each set includes complete 1:24,000 and 1:100,000-scale USGS maps (except AK).
- Crisp image resolution: Each map is hand-scanned in a process that results in crisp, color-corrected images stored in millions of colors. The result is a map that is very pleasing to look at and can produce presentation-quality prints and output.
- Grayscale hillshading: Toggles on and off to provide realistic topographic map images.
- USGS DEM information: The database is compiled from the USGS National Elevation Dataset (NED) using 1-arc-second DEM data (approximately equivalent to 30-meter resolution DEMs).
- Spatial Accuracy: The maps, DEMs, and hillshading merge together in one seamless geodetic framework with few visible boundary lines. The result is a spatially accurate data layer — for one or many maps — that will overlay other data sets smoothly. The maps are projected on the fly to match the dataframe properties found in the first data layer.
