What is the 1st step of remote sensing process?

1. 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.

What is remote sensing data processing?

Digital data processing remote sensing has the advantage of speed and statistical analysis. While the standard processing includes error corrections and supervised classifications, special image processing has become a common feature for better image interpretation.

What are the four basic components of remote sensing?

There are four basic components of a remote sensing system ( Fig. 1) including: (1) a target; (2) an energy source; (3) a transmission path; and (4) a satellite sensor (Landsat, SPOT, or the SIR-C radar) which records the intensity of electromagnetic radiation (sunlight) reflected from the earth at different …

What are principles of remote sensing?

Detection and discrimination of objects or surface features means detecting and recording of radiant energy reflected or emitted by objects or surface material (Fig. 1). Different objects return different amount of energy in different bands of the electromagnetic spectrum, incident upon it.

What is principle of remote sensing?

What are the main types of remote sensing?

There are two primary types of remote sensors:

  • Active sensors, provide their own source of energy to illuminate the objects they observe.
  • Passive sensors, on the other hand, detect natural energy (radiation) that is emitted or reflected by the object or scene being observed.

What are the pros and cons of remote sensing?

– Technology Description. – Geographical Scope Description. – Problem Description / Relevance to Water Security. – ICT Application / Outcome. – Applicability / Transferability. – Final Thoughts / Advantages & Disadvantages.

What is remote sensing, and how can it be used?

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about the Earth and other planets. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines; it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In cur

What are the uses of remote sensing?

Radar. Radar imaging can be used for important safety-related remote sensing tasks.

  • Lasers. Another type of remote sensing involves lasers.
  • Other. Other types of remote sensing include stereographic pairs created from multiple air photos (often used to view features in 3-D and/or make topographic maps),radiometers and photometers that collect
  • What are some tools used for remote sensing?

    Remote sensing is the examination of an area from a significant distance. It is used to gather information and imaging remotely. This practice can be done using devices such as cameras placed on the ground, ships, aircraft, satellites, or even spacecraft.
