What Our Clients Are Saying

"We set a new record yesterday for our mapping team. Three drone operators covered the site yesterday on mapping missions and collected over 4000 images. This preliminary image was auto processed overnight as one mosaic in 7.5 hours on one computer. This is an exceptional accomplishment and is the result of extraordinary effort by a very high end team of surveyors, drone operators, photogrammetrists and IT professionals. Congratulations and thank you to the team."
