Surveying and mapping

Land surveying, photogrammetry, remote sensing (satellite imaging and laser scanning), geographic information systems (GIS), cartography, GPS, and some aspects of geography and civil engineering are all included in the study of geospatial measurement and representation known as surveying and mapping.


The disciplines of surveying and mapping include the collection, modeling, analysis, and administration of geospatial reference data. It uses terrestrial, marine, aerial, and satellite-based sensors, measurement systems, and technologies to gather spatial and other data while operating within the geodesy scientific framework. A license to practice land surveying is granted by the state wherein the land surveying component of Surveying and Mapping is located. Land surveying involves the investigation, analysis, and application of boundary/property laws and legal principles about particular public and private properties.
