ADIGRAT UNIVERSITY 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. Basic Components of an Ideal Remote Sensing System 6. First, the term “remote sensing” was initially introduced in 1960. STAGES OF EXPLORATION AS PER UNFC NORMS The geological assessment (G) as per UNFC norms has four codes in order of increasing details. Remote sensing began in the 1840s as balloonists took pictures of the ground using the newly invented photo-camera. Module Name and Code: SPATIAL DATA ACQUISITION AND ANALYSIS, GeESM2081 Presentation focuses on representative examples of the application of Remote Sensing systems to the three main stages of … ROLE OF REMOTE SENSING . The first one is data acquisition and the second data processing and interpretation. Stages in Remote Sensing • Emission of electromagnetic radiation, or EMR (sun/self- emission) • Transmission of energy from the source to the surface of the earth, as well as absorption and scattering • Interaction of EMR with the earth’s surface: reflection and emission • Transmission of energy from the surface to the remote sensor • Sensor data output Limitations of Remote Sensing | PowerPoint PPT presentation | free to view JUNE 07, 2018 .

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. Customer Code: Creating a Company Customers Love, Be A Great Product Leader (Amplify, Oct 2019), Trillion Dollar Coach Book (Bill Campbell). II. So the stages of Remote Sensing include (Fig.1): - A source of electromagnetic radiation or EMR (Sun) - Transmission of energy from the source to the surface of the earth, through . Remote sensing systems are divided into two groups based on separate technical solutions. 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 … Clipping is a handy way to collect important slides you want to go back to later.

The vehicles or carriers for remote sensors are called the platforms. the sun) or direct (e.g. COURSE TITLE - FUNDAMENTALS OF REMOTE SENSING The RSCC is primarily geared towards university level education but some lessons may be suitable for K-12 efforts. The reactor complex is the green rectangular area located just to the left of the black cooling pond. Images from US and French remote sensing satellites monitored the activity at the site. outline. The use of remote sensing imagery to monitor emergency - Transmission of energy from surface to Remote Sensor mounted on a platform, through Energy Source or Illumination (A) ii. Remote Sensing data extensively used in all aspects of resource extraction. Before 1960 the term used was generally aerial photography. Interpretation and Analysis (F) vii. Remote Sensing System. waves,*etc. 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. The other two rely on direct contact with the source of information - which are they? Types of Satellite 3. Recording of Energy by the Sensor (D) v. Transmission, Reception, and Processing (E) vi.

Two satellite systems in use today are the Landsat and Radarsat remote sensing systems. For example, data may be collected on rice-growing land at various stages of the crop's growth, or on a volcano before and after a volcanic eruption. Now customize the name of a clipboard to store your clips. [email protected] 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. 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. Active remote sensing systems emit radiation on the study object and measure the reflected amount of radiation. 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. With respect to wavelength regions, remote sensing is classified into three categories: i. Looks like you’ve clipped this slide to already. Thermal Infrared Remote Sensing.

For some remote sensing sensors already large t archives for periods over 20 year are available via the World Wide Web (e.g., Landsat, NOAA-AVHRR). 1.2 Elements of remote sensing process There are seven elements comprise the remote sensing process from beginning to end. Even after the fire was out, the heat from the reactor was detected by infrared sensors in orbit. Types of Sensors 4. 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. 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). System Overview in Remote Sensing: Two major steps are involved in this process. See our Privacy Policy and User Agreement for details. Types of Satellite 3.

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. The source of energy (electromagnetic radiations) is a prerequisite for the process of remote sensing. (i) Reconnaissance (G4) (ii) Prospecting (G3) (iii) General Exploration (G2) (iv) Detailed Exploration (G1) Each stage generate resource data with a clearly defined degrees of geological assurance. Sensors used in Remote Sensing: (i) Those operating in the optical-IR (OIR) region, and. They are: Origin of electromagnetic energy (sun, a transmitter carried by the sensor). 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. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. 2-Active remote sensing, on the other hand, emits energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target.
