Application of the satellite positioning technology in surveying in Macao

The establishment of MoSRef has driven the popularization of Macao's satellite positioning technology. While performing "coordinate measurement", "on-site lofting", and "topographic surveying", the Macao Cartography and Cadastre Bureau will employ the satellite positioning measurement technology. Relevant technologies have raised the efficiency of work and the precision of results. Specifically, the applications of the specific satellite positioning technology in mapping in Macao can be classified into the following categories:

1. Cadastral and topographic surveying

Static and real-time kinematic satellite positioning technologies are combined with the traditional measurement technology to determine the position of boundary points, mapping control points, and surface feature points.

2. Geographic data collection

For the collection of  feature attribute data, the real-time kinematic satellite positioning method can be used to effectively acquire position data and import them into the geographic information database to provide the information required by government departments and industries for business planning.
  
3. Engineering measurement

Due to the continuous promotion and education of applications of the satellite positioning technology, relevant technologies have been widely applied to multiple engineering measurement tasks, including engineering setting out, deformation monitoring, and result inspection.
