Remote Sensing
Remote means far away. Remote sensing means sensing things from a distance. We use three as remote sensors of our five senses. Sense of sight (watching cricket from the stands), Sense of smell (smell freshly baked food) and sense of hearing (hear a telephone call) are remote sensors.Remote sensing is used in numerous fields. There are two types of remote sensing. Passive remote technology is used to record an object’s natural radiation. For example, an infrared camera on a tripod that records heat coming from a rock formation or an airplane flying over a rain forest that registers the sunlight reflected from the forest as canopy.

Active remote technology takes place when a device sends out a signal in order to gather information about an object. For example, Ships that send sonar waves to scan the ocean floor uses active remote sensing.
Everyday meteorologists use this to generate weather forecasts. Police use it to catch speeding cars and geologists use it to create maps of all kinds a special type of remote sensing called light detection and ranging or lidar is a type of active remote sensing that uses lasers.
 NASA has launched an online toolkit to make it easier for users to find, analyze and utilize the most relevant satellite data for their research, business projects or conservation efforts. The “Remote Sensing Toolkit” provides a simple system that quickly identifies relevant sources based on user input. The toolkit is designed to help users search for data, as well as ready-to-use tools and code to build new tools. “This new tool makes finding and using NASA satellite data easier than ever before, and we hope it sparks innovation among the entrepreneurial community and leads to further commercialization of NASA technology and benefits people across the world,” said Daniel Lockney, NASA’s Technology Transfer programmed executive.
