Final answer:
LiDAR and aerial photographs or satellite imagery can detect the presence of ditches and pits.
Step-by-step explanation:
The types of remote sensing that can detect the presence of ditches and pits are LiDAR and aerial photographs taken from airplanes or images created from satellites.
LIDAR (Light Detection and Ranging) uses laser technology to measure distances by illuminating a target with a laser and analyzing the reflected light. LiDAR can create highly accurate and detailed images of the topography, allowing it to detect the presence of ditches and pits.
Aerial photographs and satellite imagery can also be used to identify ditches and pits. These images can provide valuable information about the earth's surface, including the presence of various features like water bodies, vegetation, and geological formations.
