Professional scope and professional breakdown

1. Geodesy

The location data service of GNSS continuous operation reference station network refers to the activity of providing location data service through a system composed of several GNSS continuous operation reference stations, data centers and data communication networks. Global navigation satellite system (GNSS) includes Beidou satellite navigation system, GPS, GLONASS, Galileo and so on.

2. Surveying and mapping aerial photography

General aerial photography includes film aerial photography, digital aerial photography, airborne laser scanning and airborne SAR imaging.

3. Photogrammetry and remote sensing

Units engaged in the processing and provision of high-resolution satellite images shall obtain the qualification of surveying and mapping in the disciplines of photogrammetry and remote sensing.

4. Geographic Information System Engineering

Ground motion measurement refers to the activity of collecting all kinds of real geographic and spatial information and post-processing the data by using various sensors integrated on the ground moving vehicle in the moving state.

5. Engineering survey

(1) Planning survey includes urban and rural planning alignment survey, urban and rural land use survey, planning inspection survey and sunshine survey.

(2) Deformation and precision measurement include precision engineering measurement, deformation (settlement) observation and deformation measurement.

(3) Line and bridge tunnel survey includes line engineering survey, bridge survey and tunnel survey.

6. Marine Surveying and Mapping

(1) Units engaged in marine surveying and mapping activities in inland rivers, lakes and other waters shall obtain corresponding professional sub-items within the scope of marine surveying and mapping.

(2) Marine engineering survey includes sediment survey, floating mud survey, shallow stratum profile survey, underwater pipeline survey and port and waterway engineering survey.

7. Internet map service

(1) Internet map service mainly includes geographic location, uploading and labeling geographic information, and developing map database. Maps called through the wireless Internet also belong to the category of Internet map services.

(2) Geographical location refers to the service of matching the spatial coordinates with the corresponding locations of Internet maps and visually expressing the maps.

(3) Uploading and labeling of geographic information refers to a service mode that allows users to fill in the information they are interested in on the Internet map and share it with others. This information includes but is not limited to name, address, classification, attributes, images, comments, etc.

(4) Map database development refers to the development of Internet map databases and related service functions by Internet map service units for users to call and develop. Functions include but not limited to map display, map drawing, map search, bus transfer, driving route, geocoding, reverse geocoding and other map services, and forms include but not limited to API, Web Service, SDK and other map interface calling services.
