The data is the terrain visibility data of Lanzhou City, Gansu Province obtained by the research team based on sentinel-1a images of orbit lifting and descending and using sbas-insar technology. The main fields include good visibility area, perspective shrinkage area, low sensitivity area, shadow area and overlay area.
The original radar data is from the European Aeronautics and space agency, with azimuth and range resolution of 5 × 20m, suitable for monitoring the surface deformation of the land surface covered by radar images; Based on ArcGIS, the terrain visibility data of Lanzhou city is obtained by calculating the relationship between the incidence angle of radar image and the slope gradient and aspect.

The data is the terrain visibility data of Lanzhou City, Gansu Province obtained by the research team using sbas-insar technology based on sentinel-1a images of orbit ascending and descending.
Taking ArcGIS as the basic platform, using slope, aspect and grid calculation tools, calculate the relationship between radar image incidence angle and terrain, and finally obtain the terrain visibility distribution map of Lanzhou City (good visibility, perspective shrinkage, shadow area, overlapping area and low sensitive area).
Good data quality.
