Remote sensing

Definition

Remote sensing is the process of acquiring information about an object or area from a distance, typically using satellite or aerial imagery. This technology enables the analysis of soil properties, land use, and environmental changes by capturing data that can reveal patterns and conditions that are not easily observable on the ground.
