Satellite Remote Sensing
Based on the differences in the electromagnetic characteristics of different objects, satellites and spacecraft can be used as platforms for sensors to detect the nature and characteristics of ground objects. Remote sensing technology for identifying various types of ground objects is called satellite remote sensing. Satellite remote sensing is characterized by wide sightlines and high repeatability. It can effectively investigate and evaluate the surface conditions and natural resources in tourist areas. It is an important means for tourism planning and tourism resource development and management.
