This picture shows the Cornerstone Earth Group, Inc. drone team taking orthophotos to produce an orthomosaic map, which is essentially a map composed of several orthophotos or orthoimages, of a site in Nevada. An unprocessed aerial photo has inherent inaccuracies due to distortion (2-dimension images distort the curved surface of the Earth). An orthoimage adjusts the original aerial image that accounts for the distortion due to camera tilt, topographic relief, or lens distortion. This process, called orthorectification, results in an aerial image that has been geometrically corrected such that it allows for true distances to be measured. This base map will be used as comparison for future site evaluations, earthwork monitoring, modeling, and data overlays for site development. In additional to Cornerstone’s mapping, the drone produced panoramic photographs and video of this site to provide our client’s team of professionals a baseline for geotechnical and geologic review and an evaluation of past site work, grading and other conditions to further aid in site design.
