Urgently seeking the relationship between geographic information system and surveying.

There are two kinds of GIS disciplines in China, one is cartography and geographic information system, and the other is cartography and geographic information engineering. The former belongs to Neo-Confucianism-> Geography belongs to engineering-> Surveying and mapping science and technology. They are closely related. Survey data is the main source of GIS data. Measurement data include GPS data, RS data, traditional measurement data, etc. You can get other elements such as points, lines and areas, DEM data, land use change and map update data. GIS is a management tool for survey data, such as geometric correction, radiation correction and image classification of remote sensing images, vector data management and thematic map drawing.
