NICK'S DREAM SERVICE

 A drone image that has been corrected for lens distortion, camera tilt, perspective, and topographic relief (i.e., elevation changes on the Earth's surface) and stitched together in post-processing to create a large map-quality image with a high level of detail and resolution. 

 A geographic information system (GIS) shapes state and local government processes, workflows, policies, and engagement with citizens. GIS provides a means to question how we can constantly improve our environment; infrastructure; safety; health; economies; planning; engineering; and, ultimately, our world.  

 3D point cloud data, each point contains three-dimensional coordinate information, i.e., X, Y, and Z elements. Sometimes it also contains color information, reflection intensity information, echo count information, etc. 

Drones have extremely high accuracy, with aerial mapping reaching centimeter-level accuracy and mapping accuracy generally reaching newer heights. In addition, aerial mapping also has a wealth of 3D geographic information, which can capture the data of large-scale terrain.

 Drone survey allows us to obtain extensive and reliable data from inaccessible locations, unsafe steep slopes, or hazardous terrains. This means that surveyors can create a 3D computer model of the object under study and take a series of measurements in the office, without necessarily needing to be in the field or in a hazardous area to obtain data. 

The economic advantage of drone land surveying comes primarily from its low operating costs compared to its main competitors, airplanes, and helicopters, which are up to 10 times more expensive than drone topography. Besides, recent studies show drone surveying is up to five times faster than traditional land-based methods.
