Remote sensing is the process of acquiring information about the Earth's surface through the use of sensors that are not in physical contact with the surface. This technology involves the collection of data about the Earth's surface through aerial or satellite imagery, which is then analyzed to extract valuable information. Remote sensing has numerous applications, including land use/land cover classification, crop monitoring, soil moisture estimation, and disaster management.
, is a foundational resource that bridges the gap between raw data acquisition and complex spatial analysis. It is widely recognized for its structured, two-part approach: the first half focuses on the physics and technology of remote sensing remote sensing and gis basudeb bhatta pdf
