UAV AERIAL MAPPING
Midsouth Mapping, LLC. specializes in the acquisition and processing of high-resolution aerial imagery to create Orthophoto maps. With the use of accurate ground control points, orthomosaics can be rectified and georeferenced to a client’s datum. In addition, Midsouth Mapping can provide oblique photos and aerial video. Aerial mapping using photos acquired by UAVs is much more efficient, less costly, and can be delivered much faster than conventionally acquired aerial mapping. This is especially effective for smaller projects, up to 100 acres, which may not justify the expense of scheduling conventional aircraft for the acquisition of mapping. Midsouth Mapping can also provide digital terrain and surface models (DTM,DSM), contours, 3D model generation, volume computations and planimetric feature extraction.
ADVANTAGES OVER CONVENTIONALLY AERIAL MAPPING
-Fast Acquisition and Delivery
As a general rule, UAV’s can take significantly higher resolution images than satellite or manned aircraft simply because they can fly lower. UAV's are equipped with state of the art cameras and sensors that allow for easy and quick capture of aerial data. The resolution of imagery is as little as ½ inch per pixel.
Items that would be expected to be visible - manholes and utility covers, painted utility markings, striping, traffic loop detectors, differing pavements, median islands, pavement cracking.
Aerial Imagery has always been beneficial to engineers and surveyors. However, due to the expense of commercial aircraft, the costs have not always been reasonable for smaller projects. Starting with the development of the UAVs and the development of software to process the images, it is now possible to obtain accurate aerial mapping in a cost effective manner.
LIMITATIONS WITH UAV AERIAL IMAGERY
Yes, it’s true. Aerial imagery has it’s limitations. We are not here to sell you the end-all best survey tool.
Just like all other surveying tools, UAV mapping is perfect for some applications, but provide limited benefit for others.
TREE COVER - Photogrammetry based mapping does not penetrate tree canopy or heavy brush. There are methods to obtain accurate data from oblique imagery if the ground is visible from an angle. Large bodies of water are difficult to map.
SIZE - While any size parcel of land can be mapped with a UAV, parcels over 100 acres would probably be better served by convention manned aircraft based photogrammetry.
WEATHER - Extreme weather conditions like storms, rain, fog and winds over 20mph can delay acquisition of data via UAV.
LOCATION - Project sites near major airports require FAA authorization. (However, we have been successful in most of our requests for authorization.)
