In the previous video about Remote Sensing, we told you the definition of Remote Sensing. Figure 1: Stages of Remote Sensing . ROLE OF REMOTE SENSING . First, the term “remote sensing” was initially introduced in 1960. 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. Interpretation and Analysis (F) vii. ANDREW STEELE . zubairul@gmail.com Can "remote sensing" employ anything other than electromagnetic radiation? Looks like you’ve clipped this slide to already. 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.

ADIGRAT UNIVERSITY The source of energy (electromagnetic radiations) is a prerequisite for the process of remote sensing. Title: Microsoft PowerPoint - Lecture25.ppt Author: Keith Clarke Created Date: 11/28/2011 2:40:00 PM 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 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. STAGES IN REMOTE SENSING SYSTEM: The remote sensing system consists of six stages: i. 1 STAGES OF EXPLORATION AS PER UNFC NORMS The geological assessment (G) as per UNFC norms has four codes in order of increasing details. Images from US and French remote sensing satellites monitored the activity at the site. They are: Origin of electromagnetic energy (sun, a transmitter carried by the sensor). The vehicles or carriers for remote sensors are called the platforms. Remotely sensed data can be of many forms, including variations in 2. Two satellite systems in use today are the Landsat and Radarsat remote sensing systems. 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. Remote-sensing case studies of protected areas in the volume are organized in four sections devoted to (1) the changing landscape of protected lands; (2) inventory, mapping, and conservation of protected lands and waters; (3) inventory and monitoring of frontier lands; and (4) decision support for management of protected lands. See our Privacy Policy and User Agreement for details. iii. 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). 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.

Remote sensing is the science and art of obtaining infor-mation about an object through the analysis of data acquired by a device that is not in contact with the object. 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 . 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. The RSCC is primarily geared towards university level education but some lessons may be suitable for K-12 efforts. remote sesing is the art, science and tecnology to obtain reliable information of an object on the surface of the earth without comming into physical contact.
