AERIAL SURVEYDrone is an important tool for the world to have when itcomes to aerial surveys, as it allows us to get more accurateand detailed data without spending as much money on it.In Africa, a vast amount of land is stillunmapped. Using drones, this canbe easily achieved at a fraction ofthe cost. This allows for fast and accuratemapping in both 2D and 3D. This technologycan be used by a number of industries,including construction, land surveying,mining, inspection, agriculture and forestry,emergency management and humanitarianresponse.Aerial Surveying in AfricaThe use of drones for aerial surveying inAfrica has been increasing significantly. It hasbecome a more environmentally friendly formof surveying, which is ideal for remote anddifficult-to-reach areas. UAVs are also moreflexible, allowing them to access areas thatwould otherwise be difficult or impossible formanned aircraft.One of the major technological breakthroughsthat has been made in the field of aerialsurveying is the use of LiDAR (Light DetectionAnd Ranging) sensors. This helps to seethrough trees and ground cover, which canmake it harder for an aerial vehicle to capturedetailed and accurate imagery.This type of sensor is essential for highlyaccurate surveys like mineral exploration,geophysical surveying and environmentmonitoring. It has also made it possible tocollect high-density point cloud data for usein Geographic Information Systems.Aerial Digital ImageryThe use of aerial digital imagery has beenincreasing in Africa over the years. This ismainly because it is faster and easier tocollect than traditional analogue techniques,as well as providing excellent spatial andspectral resolutions.During the past decade, Africa has witnesseda significant change in the aerial digitalimagery sector. This was primarily becauseof the development of a number of differentspecialized sensor technologies which allowfor a range of different applications.Another key change in the aerial digitalimagery sector has been the emergence ofnew software and algorithms that allow forgreater accuracy and efficiency. Moreover, thishas enabled users to have more flexibilitywhen it comes to the way they use this data.Aerial digital imagery can also be used formore precise crop surveys, such as whendetermining the crop yield in a given area oranalyzing the effects of different soil types.This can help farmers to better manage theircrops in order to maximize their yield.It can also be used for assessing the conditionof a site and identifying potential hazards.This helps to protect the environment andimprove the safety of both people andanimals.The development of drones with advancedimaging technologies is changing the waywe do surveys in Africa and globally. Thishas created a market that is growing rapidlyand is expected to continue doing so in thecoming decades.This is an important tool for the world tohave when it comes to aerial surveys, as itallows us to get more accurate and detaileddata without spending as much money on it.It has also been proven to be safer and moreefficient than traditional methods.Image:microdroneswww.africasurveyorsonline.comJanuary-February issue l 2023 21
