What are the collection methods of spatial data in GIS?

There are many types of GIS data: traditional 4D data (DLG vector data, DEM elevation model data, DOM orthophoto data, DRG raster map data (basically not used now)), street view data, GPS data, 3D model data and so on.

Among them: DLG data are generally vectorized by GIS editing software, or obtained by indoor processing after being measured by field measuring instruments;

DEM and DOM data are processed by remote sensing of satellites or airplanes.

The GPS navigation data is easy to understand, that is, the signal data of GPS satellites can be obtained through mobile phones or professional GPS and Beidou navigators.

Street view data is collected by street view vehicles;

Now, 3D model data can be obtained by rapid modeling after oblique photography.

There are some unusual things such as laser point cloud data, so I won't introduce them one by one. I'm interested in private chat.
