as it determines the precision of future work in the project. Various methods have been perfected to get the accurate lay of the land and at SP Consultants we prefer to use the latest technology has to offer, like Differential Global Positioning System (DGPS) and Drone Survey.
Differential Global Positioning System (DGPS) is a current breakthrough in the technology of surveying and is without the disadvantages of previous techniques, thus enabling us to perform the survey with sub- centimetre accuracy.
Drone is an unmanned aerial and highly manoeuvrable vehicle. Retrofitted with a powerful camera and sensors the drone is capable of capturing each and every crevice of the land. It enables us to capture extensive topographical data that is capable of providing the clients with detailed information regarding their land, such as the elevation, size and descriptive illustrations of all the components it entails, natural or man-made.
DGPS works by receiving signals from GPS satellites as well as reference stations located on the ground. By comparing the satellite signals with those from the reference stations, DGPS can correct for errors caused by factors like atmospheric interference and satellite clock drift, significantly improving the accuracy of location data collected by drones.
Drone DGPS mapping has a wide range of applications across various industries, including:
