The Loess Plateau is the world’s largest region of loess deposition and erosion and located around the middle reach of the Yellow River in North China. It is considered one of the most unique and valuable geographical study areas in the world. In this project, three test areas are selected to extract topographic factors.

The selection of the test areas directly affects the reliability and stability of the experimental results. Therefore, the following basic principles should be followed in the selection of test areas:
|
|
|
1. Scientific principle: The selection of test areas should fully reflect the existing research achievements in loess topography research, Digital Terrain Analysis theory, etc., in accordance with its basic laws and characteristics.

|
|
2. Typicality principle: The selection of test areas should cover the basic landform types of the Loess Plateau, and each test area should have the typical characteristics of the landform type area.

3. Integrity principle: The completeness of data acquisition will directly affect the reliability of the experimental results. Therefore, the basic data of the selected test areas is required to be sufficient, the data is accurate, and the metadata is complete.
