GPS Surveying and Mapping

The surveying and mapping segment of the real estate industry is simultaneously evolving with the expansion of technology. One great proof is the steady redefining of various tools and equipment needed to enhance productivity and obtain highly accurate data.

Professional surveyors and mapping personnel specialise in offering a wide variety of services that impact ownership and conveyance of real estate property. They establish base maps with contours, perform stationing, create plan and profile sheets, and develop cross-sections, among other things. To deliver the best results to clients, these professionals make use of the near pinpoint accuracy offered by global positioning system (GPS) to get precise surveying and mapping results within a small amount of time. This led to the reduction of the number of equipment and labour hours generally required to get the same data when conventional processes and techniques are employed. In modern times, it is possible for a single surveyor to complete a task in one day what used to take weeks for an entire team to accomplish. GPS is unaffected by rain, wind, or reduced sunlight, allowing surveyors to continue getting data amid various weather conditions. Unlike conventional methods, GPS surveying is not limited by constrains like line-of-sight visibility between reference stations. Additionally, GPS is flexible such that the spacing between stations can be increased, permitting survey stations to be situated at highly accessible sites, and not on hilltops as traditionally required. Remote GPS devices are portable and can be carried by one person in a backpack or fastened on a car's roof. Professionals may use GPS radio communication link to obtain real-time, continuous, and accurate information – that used to be impossible with optical survey instruments.


GPS provides descriptive three-dimensional positioning data regarding natural and artificial features of land that can be displayed on maps and models. This data can then be translated into graphical images of land depicting mountains, rivers, forests, endangered species, precious minerals, and several other resources. Such information becomes the primary input to geographic information system (GIS), which assembles, stores, manipulates, and displays geographically referenced data.

Various institutions around the world like government agencies, scientific organisations, and commercial establishments are using surveys and maps derived from GPS and GIS. They depend on these technologies to get accurate data needed to make timely decisions and find ways to wisely use resources.
