GPS Land Surveys

GPS Land surveying is a scientific method of determining, analyzing as well as evaluating the terrestrial or 3D space position of points and the distances with angles between them. It offers the advantages of higher accuracy of survey data and rapid project turnaround. The land surveying firms use Global Positioning System (GPS) as a tool for land surveys to precisely identify the positioning of points. Global Positioning System (GPS) land surveying tool operates directly through satellites which emit signals to the land based sophisticated satellite receivers. The satellite receiver then transmits those signals to the data collector, which stores the data in it. After the data has been received, the company downloads the data into the computer and the computer software resolves the position of the points within a few millimeters. It effectively assists in the subdivision of land, research and interpretation of survey plans, road boundary realignment, building development, etc.
To accomplish objectives of land surveying, land planning and surveying companies and their land surveyors use the elements of geometry, engineering, trigonometry, mathematics, and physics. The land planning and surveying companies offer GPS tools to successfully understand and identify the terrestrial points for their customers. GPS is used for more precise recording, like grid layouts, excavation plans and topographical surveys, where high level of accuracy up to millimeter is required. The GPS land surveying technique helps in real estate, development, engineering, telecommunications, and environmental industries, both in the public and private sector as well.
Global Positioning System (GPS) land surveys are used to study the surface, shape as well as features and boundaries of the land. It provides the meticulous descriptions and survey plans of the features including vegetation cover and elevations, etc through points on maps. The result of GPS land survey is the pictorial representation that allows the land surveyors to offer exact 3D drawings that can save time and money for building design or environmental projects. Perfect measurement and accumulation of these graphic positions is one of the fundamental elements of GPS land surveying. The benefit of GPS land surveying is that it is much more accurate than hand-measuring or other traditional equipments.
GPS land surveys assist engineers, building contractors and architects through GeoTracker reporting, construction staking and earth quantity calculations. It also helps planners to identify the features on given land surface and any special location in terms of coordinates. There are various other land surveying techniques involved in the procedure of land surveying like: ALTA / ACSM Land Title Surveys (ALTA Surveys), High-Definition Surveying – HDS (3D Laser Scanning), Topographic Surveys, Environmental Surveys, and Geodetic Survey.
