Land surveying – mapping the world in 2d & 3d
Land Surveying is the accurate collection of three-dimensional points and the relationship between them to map the topography of the Earth’s surfaces, be that:
- above the ground – buildings and structures – from the ground or the air;
- below the ground – mine works or buried services;
- above water – marine buildings and structures;
- below water – lake, river and sea beds.
Land Surveying is the technique, profession, and science of determining the terrestrial or three-dimensional position of points and the distances and angles between them.Source: Surveying – Wikipedia, the free encyclopedia
The tools and techniques used are as varied as the environments surveyed. From GPS receivers, Theodolites, dumpy levels, the humble pocket tape through to electronic tapes, digital cameras, smartphones, drones and Laser Scanners. Many of these techniques allow data to be recorded remotely. Potentially important in hazardous or dangerous conditions.
Land Surveyors have to be adept in a number of fields including Mathematics, Physics, Engineering and Law. By using Geometry & Trigonometry they can understand complex three-dimensional relationships. Physics to understand the movement and propagation of electromagnetic waves, to calculate distance and understand hidden objects. Law to interpret and analyse boundary data in the event of a boundary dispute between neighbours.
Setting out is the reverse of the Land Survey process, whereby a Land Surveyor takes a design and accurately marks out or sets out the position/dimensions of the design in the real world.
