It is expected that orthometric heights with a target precision of 3–5 cm would be determined by GNSS surveying and the local geoid model, but an improvement of the geoid model in mountainous areas is still necessary. The other 9 points, located in coastal areas, had a difference smaller than 3 cm compared to the official orthometric height. As a result, it was found that the difference in heights at 12 points did not exceed 5 cm. Among the 19 points, the precision of the official orthometric heights at 12 points located in mountainous areas is known to be larger than 10 cm hence, the GNSS-derived orthometric heights were calculated using Trimble business center (TBC), Leica geo-office (LGO), and Giodis, and compared with each other. Thus, GNSS surveying was conducted at 19 points and GNSS-derived orthometric heights were computed. One of the necessities of a local geoid model is to efficiently determine the orthometric height in terms of time and cost. The degree of fit of KNGeoid18 was calculated to be approximately 2.3 cm. As a final product of the study, the hybrid geoid, Korean National Geoid model 2018 (KNGeoid18), was modeled by fitting the gravimetric geoid to a total of 2,791 points of global navigation satellite system (GNSS)/leveling data located over the entire Korean peninsula.
The GEM file can then be loaded on-board a System 500 or System 1200 sensor or can be used to calculate the geoid-ellipsoid separation within SkiPro or Leica Geo Office.

This PC application allows a geoid model to be read from an ASCII file and converted to the GEM format. In addition, airborne, shipborne, and Danish Technical University 2010 (DTU10) altimeter gravity data, as well as a terrain model, were applied for geoid modeling. Geoid Model Reader 1.3.1 (latest) See all. Thus, a gravimetric geoid was newly developed by the “Remove-Restore” technique using the experimental gravity field model 2016 (XGM2016) and more than 12,000 points of land gravity data. In addition, a new version of the global geopotential models which were developed based on observations by the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite are available.

It is expected that the GEM file referenced in the DBX will be in the same folder as the DBX files. Note 3: If a point has an ellipsoidal height, LISCAD will attempt to use the appropriate Leica Geoid Model (GEM file) to convert the height to an orthometric height.

Since 2008, new land gravity data showing a homogeneous distribution and high precision have been obtained in Korea. These files are converted from the data provided by Natural Resources Canada.

It is no longer required that the survey data is processed in an external software since Leica MobileMatriX integrates all data processing within the GIS.Lee, J. Leica MobileMatriX can be used in the field and in the office, providing a consistent, intuitive user interface. It directly integrates survey related data collection and processing functionality into ArcGIS. Leica MobileMatriX is a Windows-based field solution for the interactive processing, visualisation and maintenance of feature and survey data. Furthermore, Leica MobileMatriX on ArcGIS Edition v2.0 also supports ESRI ArcGIS 9.2. The new Glonass and GPS processing capability within Leica MobileMatriX’ RTK option improves signal availability for high accuracy Real-Time Kinematic (RTK) mapping tasks.
The new version 2.0 now supports Leica ATX1230 GG and Leica ATX900 antennas as well as Leica Geosystems laser rangefinder products. Leica Geosystems (Swizerland) has released Leica MobileMatriX version 2.0 a multi-sensors GIS solution for capturing GIS data directly in the field.
