Question

sir please solve this question. It is my assignment problem of 10 marks so please give answer like that sir i want detailed answer and all the part should answered and explain each and every part i am sending this question for the 2nd time last time i didnt get complete answer sir if u want to take time take ur time please give me best solution of it
Thankyou so mch??

Part -A 10 Marks) The cyclonic storm Ockhi which hit the west coast of India during Novembr-December 2017 claimed several lives and caused severe damages to structures and property across the coastal belt. The cyclone uprooted coconut trees and caused extensive damages to houses, power lines and other infrastructure in Lakshadweep islands. The extent of damage was so huge, that to assess the destruction caused by the cyclone took several days. The assessment of damages can be done by various traditional and advanced methods like Remote Sensing. In this context, debate on the statement: 'Remote sensing is the best tool for assessing the damages in an area Your debate should include: A.1.1 A.1.2 A.1.3 A.1.4 Concept of remote sensing Various steps involved in remote sensing Description of any other method which may be suitable for assessment of damage Justification of your stand

Remote Sensing

Remote sensing is a science of obtaining   information about an object or phenomenon without making physical contact with the object. Remote sensing is used in numerous fields, including geography, land surveying and most Earth Science disciplines (for example, hydrology, ecology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications.

Remote sensing has a wide range of applications in many different fields:

Coastal applications: Monitor shoreline changes, track sediment transport, and map coastal features. Data can be used for coastal mapping and erosion prevention.

Ocean applications: Monitor ocean circulation and current systems, measure ocean temperature and wave heights, and track sea ice. Data can be used to better understand the oceans and how to best manage ocean resources.

Hazard assessment: Track hurricanes, earthquakes, erosion, and flooding. Data can be used to assess the impacts of a natural disaster and create preparedness strategies to be used before and after a hazardous event.

Natural resource management: Monitor land use, map wetlands, and chart wildlife habitats. Data can be used to minimize the damage that urban growth has on the environment and help decide how to best protect natural resources.

Stages in Remote Sensing

The process of remote sensing involves a number of processes starting from energy emission from source to data analysis and information extraction. The stages of remote sensing are described in follows steps:

Source of Energy

The source of energy (electromagnetic radiations) is a prerequisite for the process of remote sensing. The energy sources may be indirect (e.g. the sun) or direct (e.g. radar). The indirect sources vary with time and location, while we have control over direct sources. These sources emit electromagnetic radiations (EMRs) in the wavelength regions, which can be sensed by the sensors.

Interaction of EMR with the Atmosphere

The EMR interacts with the atmosphere while traveling from the source to earth features and from earth features to the sensor. During this whole path the EMR changes its properties due to loss of energy and alteration in wavelength, which ultimately affects the sensing of the EMR by the sensor. This interaction often leads to atmospheric noise (it will be discussed in separate topic).

EMR Interaction with Earth Features

The incident EMR on the earth features interacts in various ways. It get reflected, absorbed, transmitted & emitted by the features and ground objects. The amount of EMR reflected, absorbed, transmitted and emitted depends upon the properties of the material in contact and EMR itself.

Detection of EMR by the remote sensing sensor

The remote sensing device records the EMR coming to the sensor after its interaction with the earth features. The kind of EMR which can be sensed by the device depends upon the amount of EMR and sensor’s capabilities.

Data Transmission and Processing

The EMR recorded by the remote sensing device is transmitted to earth receiving and data processing stations. Here the EMR are transformed into interpretable output- digital or analogue images.

Image Processing and Analysis

The digital satellite images are processed using specialized software meant for satellite image processing. The image processing and further analysis of satellite data leads to information extraction, which is required by the users.

Application

The extracted information is utilized to make decisions for solving particular problems. Thus remote sensing is a multi-disciplinary science, which includes a combination of various disciplines such as optics, photography, computer, electronics, telecommunication and satellite-launching etc.

Method of hazard assesment;

Ground Based Assesment - It is an old conventional method of damage assesment.In this method,survey & analyse of damage area is done by visual inspection.man need to enter in the damage area & inspect carefully and predict the intensity of damage caused by the natural disaster.
