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. 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. 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 … The collection of information about Earth surfaces and phenomena using sensors not in physical contact with the surfaces and phenomena of interest. They are: Origin of electromagnetic energy (sun, a transmitter carried by the sensor). STAGES IN REMOTE SENSING SYSTEM: The remote sensing system consists of six stages: i. 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.

Interaction with the Target (C) iv. The reactor complex is the green rectangular area located just to the left of the black cooling pond. Remote Sensing data extensively used in all aspects of resource extraction. - Transmission of energy from surface to Remote Sensor mounted on a platform, through outline. The vehicles or carriers for remote sensors are called the platforms. Remote Sensing System. Visible and Reflective Infrared Remote Sensing. Before 1960 the term used was generally aerial photography. SALES ENGINEERING MANAGER, DIGITALGLOBE ASIA-PACIFIC 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. Two satellite systems in use today are the Landsat and Radarsat remote sensing systems. “Remote Sensing is the art and science of acquiring information about the earth surface without having any physical contact with it.

Can "remote sensing" employ anything other than electromagnetic radiation? Sensors used in Remote Sensing: (i) Those operating in the optical-IR (OIR) region, and. Remote sensing systems are divided into two groups based on separate technical solutions. Types of Satellite 3. Since the end of the 1960s, remote sensing has been used in plant disease detection with increasing frequency. **These*methods*workonthe*same*principles*as* electromagneticremotesensing,*but*compriseasmall*part*of*the totaldata*produced*from*remote*sensing.

The RSCC is primarily geared towards university level education but some lessons may be suitable for K-12 efforts. 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 REGIONAL TRAINING ON THE USE OF DRONES, SATELLITE IMAGERY AND GIS. Figure 1: Stages of Remote Sensing . 1.2 Elements of remote sensing process There are seven elements comprise the remote sensing process from beginning to end. Remote sensing began in the 1840s as balloonists took pictures of the ground using the newly invented photo-camera. Limitations of Remote Sensing 5. The stages of remote sensing are described in follows steps: Source of Energy. 1. the sun) or direct (e.g. Basic Components of an Ideal Remote Sensing System 6. COURSE MATERIAL zubairul@gmail.com ii. Or, it could be a multitemporal sensing whereby data are collected on the same site at different dates.
