Describe the remote sensing technique?

Remote sensing is a method of collecting data about an object or area without physically being in contact with it. This technique involves using sensors, such as cameras or satellites, to capture images or other data from a distance. These sensors can detect various wavelengths of light, such as visible, infrared, or microwave, to gather information about the object or area being studied.

Remote sensing can be used for a variety of purposes, including monitoring environmental changes, mapping land use and land cover, and assessing natural disasters. It is commonly used in fields such as agriculture, forestry, urban planning, and climate science.

The data collected through remote sensing can be analyzed and processed to create maps, models, and other visualizations that provide valuable insights into the object or area being studied. This information can help researchers, policymakers, and other stakeholders make informed decisions and take appropriate actions based on the findings.
