Remote sensing is the science of obtaining information about objects or areas from a distance, typically from aircraft or satellites. Remote sensing systems/ se nsors can be basically g rouped into two types: passive and active sensors. Traditional methods of obtaining this information are census and ground surveying. Remote Sensing Platforms and Types In this article one can see remote sensing platforms and types with a comparison between different types of sensors. What is Remote Sensing? A Lidar (Light Detection and Ranging) image created with data collected by NOAA's National Geodetic Survey. As remote sensing technology continues to develop and improve, we’re seeing more uses and opportunities to create value in new industries and fields of study — from environmental science to public safety to telecommunications. Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Active sensor Remote Sensing. Types of remote sensing 1. Several different remote sensing methods are available today, and each comes with strengths and limitations. Satellite remote sensing measuring entering and leaving flux of radiation from top of the atmosphere is one of the most powerful tools in climate change ecology. This is done by capturing the reflected radiation/energy. These types of sensors are useful for measuring the vertical profiles of aerosols, forest structure, precipitation and winds, sea surface topography, and ice, among others. The tabular comparison is made between satellite sensor, altitude, life, sensor bands, sensor resolution, … Special cameras collect remotely sensed images, which help researchers "sense" … Remote sensing is the process of acquiring information, detecting, analyzing, monitoring the physical characteristics of an area by recording it is reflected and emitted radiation energy without having any physical contact with the object under study. The use of satellites is advantageous as it can generate a systematic and repetitive coverage of a large area and provide information about the health of the vegetation. Sergey Venevsky, in Encyclopedia of Ecology (Second Edition), 2019. Remote sensing is the acquiring of information from a distance.

The main s ource of energy for remote sensing comes from the su n. Remote sensing technology can be used to prepare maps of crop type and delineating their extent.
