Surdex founder Earl R. HoffmannDo What You love, Love What You Do

Company founder Earl R. Hoffmann, Sr. grew up with a love for aviation. He began his flying career as a pilot in Naval Aviation. Back in 1954, in an effort to combine his love of flying with his enthusiasm for serving the industry, Mr. Hoffmann founded Surdex Corporation, which stands for SURvey, Design, EXploration.

Since its incorporation over 60 years ago, Surdex has grown from a startup aerial photography firm to one of the most technologically advanced digital mapping firms in the photogrammetric industry. With our own fleet of aircraft and multiple acquisition options, Surdex provides complete geospatial solutions for both the public and private sectors:

Our founder’s passion is still integrated into our operational philosophy today, and as we look forward. With the most advanced technology incorporated into our production processes, we can work quicker without deviating from our clients’ accuracy and quality requirements and without risk of jeopardizing project schedules. We will continuously keep on the crest of cutting-edge technologies to work better, faster and in a cost-effective manner for our clients.
