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]
NTRIP was developed by the German Federal Agency for Cartography and Geodesy (BKG) [3] and the Dortmund University Department of Computer Science. [4] Ntrip was released in September 2004. [5] The 2011 version of the protocol is version 2.0. [6] NTRIP used to be [7] an open standard protocol but it is not available freely (as of 2020).
Data input is therefore flexible and fewer points need to be stored than in a raster DEM, with regularly distributed points. While a TIN may be considered less suited than a raster DEM for certain kinds of GIS applications, such as analysis of a surface's slope and aspect, it is often used in CAD to create contour lines. A DTM and DSM can be ...

Surveying — Survey-Grade GNSS receivers can be used to position survey markers, buildings, and road construction. [6] These units use the signal from both the L1 and L2 GPS frequencies. Even though the L2 code data are encrypted, the signal's carrier wave enables correction of some ionospheric errors.
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.
Therion is free and open-source cave surveying software designed to process survey data, generate maps and 3D models of caves, and archive [3] the data describing the cave and the history of exploration. Therion was developed by the Slovak cavers Martin Budaj and Stacho Mudrak [4] but is available in English.
