A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1]
Construction surveying and engineering surveying: topographic, layout, and as-built surveys associated with engineering design. They often need geodetic computations beyond normal civil engineering practice. Deformation survey: a survey to determine if a structure or object is changing shape or moving. First the positions of points on an object ...
The type of site survey and the best practices required depend on the nature of the project. [1] Examples of projects requiring a preliminary site survey include urban construction, [ 2 ] specialized construction (such as the location for a telescope) [ 3 ] and wireless network design.
Typically national mapping grids have significant distortion and are often not suitable for precise engineering design and construction. For major infrastructure projects specifically designed low distortion engineering grids can be used, an example being the Transport for London London Survey Grid , or tailored snake projections which can be ...

Precise positioning is increasingly used in the fields including robotics, autonomous navigation, agriculture, construction, and mining. [2]The major weaknesses of PPP, compared with conventional consumer GNSS methods, are that it takes more processing power, it requires an outside ephemeris correction stream, and it takes some time (up to tens of minutes) to converge to full accuracy.
Geomatics engineering is a rapidly developing engineering discipline which focuses on spatial information (i.e. information that has a location). [17] The location is the primary factor used to integrate a very wide range of data for spatial analysis and visualization.
SSDMSurveryObject is the most important abstract class in SSDM. Its Survey_ID and Survey_ID_Ref class members are used to identify the relationship for all geographic features created by a particular survey project. [6] It defines the basic data of a survey object such as type of survey, survey project name, survey work category, and start/end ...
