This section mainly introduces terrain analysis operation and related precautions in operation mode. Terrain analysis is to analyze the position and shape of terrain data in 3D scene, and various hidden information can be obtained to assist decision-making.

Click the Terrain Analysis button to pop up the Terrain Analysis operation panel. You can perform the following analysis:

• Submerge analysis : Simulate submergence within a specified range in a 3D scene.
• Contour analysis : Analyze contours of terrain data within a specified range in a 3D scene.
• Slope and Aspect Analysis : Analyze the slope and aspect of terrain within a specified range in a 3D scene.
• Ground Excavation Analysis : Perform excavation analysis of terrain, white model, BIM and oblique photography 3D models in 3D scenes.
