500,000 scale projects (4° x 6°)

Like the more detailed projects, our 1:500,000 scale maps are created using published geologic references and a base of Landsat Imagery and shaded relief. Data can be provided in a standard or other client-specified coordinate system to rapidly integrate with a working project environment. We also provide technical client support to facilitate effective use of our data in your geologic analysis.
