Enumerate the significant steps involved in digital image processing.

Digital image processing plays a crucial role in geoinformatics for disaster management. It enhances, analyzes, and interprets remotely sensed images to assess disaster-prone areas, monitor environmental changes, and aid in disaster response. The significant steps involved in digital image processing are as follows:  

1. Image Acquisition  
   The first step involves capturing images using various sensors on satellites, drones, or aircraft. These images can be in different spectral bands, including visible, infrared, and microwave. The choice of sensor depends on the type of disaster being monitored, such as floods, earthquakes, or forest fires.
