1. Aerial remote sensing.

Aerial Remote Sensing ( Aerial Remote Sensing Airborne remote sensing), also known as airborne remote sensing, reconnaissance developed refers to the use of various aircraft, airships, balloons and other remote sensing technology in the air as sensor carriers, and is a multi-functional comprehensive detection technology by aerial photography. According to the working altitude and application purpose of the aircraft, it is divided into three types of remote sensing operations: high-altitude (10,000-20,000 meters), medium-altitude (5,000-10,000 meters) and low-altitude (<5,000 meters). It has the characteristics of mobility and flexibility.

Second, the application platform.

The aircraft is the main platform for aerial remote sensing, which has the characteristics of high resolution, short survey period, not limited by ground conditions, and convenient data. High-altitude balloon or airship remote sensing has the characteristics of high flight altitude, large coverage, long stay time in the air, low cost, and simple flight control, and can also carry out remote sensing activities in the stratosphere, which is not easily accessible by aircraft and satellites.

The importance of remote sensing technology is not limited to the treatment of black and odorous water bodies. At present, remote sensing technology has been widely used in meteorological observation, earth resources survey, environmental pollution monitoring, monitoring, marine monitoring, land use planning, vegetation classification, crop yield investigation and crop pest monitoring. According to the commonly used magnetic spectrum of the electric register, remote sensing is divided into visible light remote sensing, infrared remote sensing, multi-spectral remote sensing, ultraviolet remote sensing and microwave remote sensing.

Remote sensing technology has been widely used in meteorological observation, earth resources survey, environmental pollution monitoring, monitoring, marine monitoring, land use planning and rezoning, vegetation classification, crop yield investigation and crop disease and pest monitoring.

At present, the main direction of remote sensing technology research is to improve the resolution of remote sensors and the ability to comprehensively utilize information, and to develop advanced remote sensors and information transmission and processing equipment, so as to realize the all-weather work of remote sensing systems and obtain information in real time, and gradually expand from the ultraviolet spectrum to X-rays and rays, and from a single electromagnetic wave to the comprehensive application of sound waves, gravitational waves, and other waves.

A remote sensor is an instrument that senses the environmental radiation or reflects electromagnetic waves of ground objects from a distance. Now there are more than 20 kinds of common ones, in addition to visible light cameras, infrared cameras, ultraviolet cameras, infrared scanners, multispectral scanners, microwave radiation and scatterometers, side-looking radars, thematic imagers, imaging spectrometers, etc.

Fundamentals of Remote Sensing Technology:

Any object has spectral properties, specifically, they all have different properties of absorption, reflection, radiation spectra. The reflection of various objects in the same spectral region is different, and the reflection of the same object to different spectra is also significantly different. Even the same object, at different times and places, has different spectra of reflection and absorption due to different angles of sunlight.

Remote sensing technology is based on these principles to make judgments on objects. Remote sensing technology usually uses three spectral bands: green, red and infrared. The green light segment is generally used to detect the properties of groundwater, rocks, and soils; The red light segment detects plant growth, change and water pollution. The infrared segment detects land, minerals and resources.
