This data must often be "cleaned" to eliminate discrepancies between surveys, but it still forms a valuable set of information for large-scale analysis. The original American topographic surveys (or the British "Ordnance" surveys) involved not only recording of relief, but identification of landmark features and vegetative land cover.
The Public Land Survey System (PLSS) is the surveying method developed and used in the United States to plat, or divide, real property for sale and settling. Also known as the Rectangular Survey System, it was created by the Land Ordinance of 1785 to survey land ceded to the United States by the Treaty of Paris in 1783, following the end of the ...
Surveying or land surveying is the technique, ... Prominent new technologies include three-dimensional (3D) scanning and lidar-based topographical surveys.
Land surveys: These detail the boundaries of a parcel of land. Topographic surveys: These illustrate the plane and elevation of the land. They’re often required for site work such as road ...
A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map ...
Land survey may refer to: Topographic surveying and mapping, the survey of landscape features for general mapping purposes; Civil engineering surveying, a survey of local topographic features for engineering purposes; Cadastral surveying, the surveying of specific land parcels to define ownership
Cadastral surveyors in Alaska. One of the primary roles of the land surveyor is to determine the boundary of real property on the ground. That boundary has already been established and described in legal documents and official plans and maps prepared by attorneys, engineers, and other land surveyors.
Land surveys and surveys of existing conditions are generally performed according to geodesic coordinates. However, for the purposes of construction a more suitable coordinate system will often be used. During construction surveying, the surveyor will often have to convert from geodesic coordinates to the coordinate system used for that project.
