Best Digital Map Product - Gold Award:Authoritative US Topo & GeoChange Maps

What are Authoritative US Toposand

GeoChange Maps?

Authoritative US Topos digital maps are produced from scans of the entire database of US topographic maps.

Digitized maps are geo-referenced and processed for color consistency.

Authoritative US Topos are the basis of our GeoChange map product, paired with recent NAIP aerial photography, and producing a stand alone reference.

What makes our product unique?

Authoritative US Topos and GeoChange maps are produced using our unique digitization process designed to produce GIS data from conventional maps.

All quads (the same paper maps used in the production of DRGs) are scanned in high resolution at 500 dpi then processed to 250 dpi without losing digital quality.

Our 1:24,000 scale digital topos line up impeccably with 1:12,000 scale imagery, largely due to USGS field surveying and quality standards

How do we produce ourGeoChange Maps?

Authoritative US Topos are paired with aerial photography to produce GeoChange composites, which allow map features to be read over imagery.
