Davidson Landing Orthomosaic, September 2017

Drones can be used to produce ultra high definition images with high relative accuracy. Accurate measurements can be made using orthomosaic images such as this Davidson Landing orthomosaic. It took less than 20 minutes to capture all the images needed to produce this orthomosaic of South Thorne Bay’s Davidson Landing public slips. The drone was 125 feet above the harbor when it captured the images. Note that the original product tiff file was 65 megabytes, and conversion to 25 MB and 2MB jpeg files resulted in degraded resolution in this image. The site specific orthomosaics are a cost-effective, useful planning tool. Image resolution is markedly greater than generally available satellite imagery and aerial (manned aircraft).
