ADIGRAT UNIVERSITY Remote Sensing -II: Energy resources, energy interactions with earth surface features and atmosphere, resolution, sensors and satellite visual interpretation techniques, basic elements, converging evidence, interpretation for terrain evaluation, spectral properties of water bodies, introduction to … Remote sensing systems are divided into two groups based on separate technical solutions. Remote Sensing Remote Sensing is: The art and science of obtaining spatial information about an object or phenomenon without being in direct contact with the object (Jensen 2000). See our User Agreement and Privacy Policy. This is done by sensing and recording of reflected and emitted energy.” In the process of Remote Sensing involves an interaction between the incoming radiation and interest of target. The vehicles or carriers for remote sensors are called the platforms. atmosphere - Interaction of EMR with earth’s surface. Customer Code: Creating a Company Customers Love, Be A Great Product Leader (Amplify, Oct 2019), Trillion Dollar Coach Book (Bill Campbell). Even after the fire was out, the heat from the reactor was detected by infrared sensors in orbit. The use of remote sensing imagery to monitor emergency 1. REGIONAL TRAINING ON THE USE OF DRONES, SATELLITE IMAGERY AND GIS. 1.2 Elements of remote sensing process There are seven elements comprise the remote sensing process from beginning to end. Interaction with the Target (C) iv. Types of Satellite 3. Satellite remote sensing data have been widely used for vegetation phenology monitoring over large geographic domains using various types of observations and methods over the past several decades. The stages of remote sensing are described in follows steps: Source of Energy. Remote sensing techniques are replacing traditional methods in field or laboratory analysis when repetitive large-scale measurements are required, representing the only feasible approach for obtaining these data. Limitations of Remote Sensing 5. See our User Agreement and Privacy Policy. Whiz quiz. Can "remote sensing" employ anything other than electromagnetic radiation?

Types of Remote Sensing Based on Source of Energy Platform 2. **These*methods*workonthe*same*principles*as* electromagneticremotesensing,*but*compriseasmall*part*of*the totaldata*produced*from*remote*sensing. With respect to wavelength regions, remote sensing is classified into three categories: i. Typical examples of platforms are satellites and aircraft, but they can also include radio-controlled aeroplanes, balloons, kits for low altitude remote sensing, as well as ladder trucks or ‘cherry pickers’ for ground investigations. First, the term “remote sensing” was initially introduced in 1960. ii. Images from US and French remote sensing satellites monitored the activity at the site. If you continue browsing the site, you agree to the use of cookies on this website. However, new methods and technologies for sensing of the Earth’s surface were moving beyond the traditional black and white aerial photograph, requiring a new, more comprehensive term be established. Energy Source or Illumination (A) ii. Clipping is a handy way to collect important slides you want to go back to later. Introduction to Remote Sensing, Earth Observation Optical & Radar Satellites . The first one is data acquisition and the second data processing and interpretation. Passive remote sensing systemsmeasure existing radiation such as the reflected solar radiation from the earth’s surface. COURSE CODE - GeES2081 You can change your ad preferences anytime. The technology of modern remote sensing has a very long history, dating back to the end of the 19th century with the invention of the camera. iii. The source of energy (electromagnetic radiations) is a prerequisite for the process of remote sensing. Clipping is a handy way to collect important slides you want to go back to later. COURSE TITLE - FUNDAMENTALS OF REMOTE SENSING Types of Sensors 4. Interpretation and Analysis (F) vii. Active remote sensing systems emit radiation on the study object and measure the reflected amount of radiation. Before 1960 the term used was generally aerial photography.

They are: Origin of electromagnetic energy (sun, a transmitter carried by the sensor). introduction objective stages of remote sensing elements of remote sensing characteristices of sensors applications of remote sensing. TGRS-00007-2001 Madhok & Landgrebe, “A Process Model for Remote Sensing Data Analysis” 2 A Process Model for Remote Sensing Data Analysis Varun Madhok and David A. Landgrebe, Life Fellow, IEEE Abstract-- Remote sensing data is collected and analyzed to enhance understanding of the terrestrial surface– in composition, in form or in function.

Since the end of the 1960s, remote sensing has been used in plant disease detection with increasing frequency. Types of Sensors 4. The energy sources may be indirect (e.g. Active Remote Sensing: It makes use of sensors that detect reflected responses from objects that are irradiated from artificially-generated energy sources, such as radar. Sensors used in Remote Sensing: (i) Those operating in the optical-IR (OIR) region, and. Of our five senses (sight, hearing, taste, smell, touch), three may be considered forms of "remote sensing", where the source of information is at some distance. Looks like you’ve clipped this slide to already. Energy Source or Illumination (A) - the first requirement for remote sensing is to have an energy source which illuminates or provides electromagnetic energy to the target of interest.
