Remote sensing is the technology that observes and analyses the geographical area’s characteristics without sensing them. Generally, remote sensing uses a system called Geographical Information System (GIS). The system is intended to observe the earth’s surface. This includes identifying, warehousing, rectifying, and investigating the information organized. This will be done with the help of computerized dedicated software.

This article is exclusively for the one who is emerging on PhD research topics in remote sensing and GIS!!!

In the following passages, we discuss the basic ideas to advance concepts involved in the Geographical Information System and remote sensing. Here, we have stated you with the overview of remote sensing in detail.

What is meant by Remote Sensing?

• Generally, remote sensing is the technology that observes the earth’s surface and its entities with the help of satellites, airplanes, and drones without making any interruptions to the objects over sensors. The data of the earth surface is stated, as geographical information here
• The information can be classified into two sorts, spatial data & non-spatial data. The features of the spatial data are signified by the arrangement of the structure and linear situations
• The backbone of the spatial data lies in the virtual or hard copy maps according to the geographical information. The maps are meant to represent the geographical area and the surface objects
• The landscapes of the maps indicate the connection of the earth’s surface corresponding with characters in the map. The plotted traits of the objects are mentioned in the form of symbols and colors.

In the following passage, we will see about the important functionalities involved in the Geographical Information System. As this is very important, it is a worthy note to take. Our experts have mentioned to you the details which will be in an understandable manner.

What are the Major Functions of GIS?

• Procurement of Information (non-spatial & spatial)
• Handling of the  Information (control of the data)
• Examination of the Information (scrutiny of the statistical and Spatial data)
• Warehousing the Information (improved collation of the data)
• Final Outcome Format (tabular, dashboards, diagrams, charts)

These are the notable working modules that are running behind the Geographical Information System. As we are mentioned this in a simplified way, we hope that this would be an easy thing to be remembered.

The source of the remote sensing is the pictures. The data gathered by the sensors are always in the form of images. Let’s get started and try to understand the tasks involved.

Major Tasks in GIS and Remote Sensing

• Cataloguing the images
  • This is a very commonly used first step in every software fields
  • This is the primary task in the GIS and remote sensing. The classification of the remote sensing images are based on the usage of the land area and the shelters of lands
  • The cataloging of the images are known as land use & cover classification and scene classification
  • This is done with the help of sensors which is assimilated from the satellites  and unmanned devices like (UAV) Unmanned Aerial Vehicles
• Segmentation of the Image
  • Generally it works on an end to end basis which can classify every pixels/particle involved in the images
  • It is otherwise called semantic segmentation
• Discovering the Changes
  • It is the process that identifies the modifications done to the remote sensing multi-temporal pictures
  • If the number of multi-temporal pictures amplified then it would be a complex one
• Combination of the images
  • This is the very essential process that generates the spatial & spectral tenacities in a predetermined process
  • The high-quality multispectral pictures will be yielded with the help of pan-sharpening which makes abrasive of the multispectral images into high-resolution images
• Discovery of the Objects
  • The name itself indicates that it is the task which discovers the various object in the picture
  • Artificial intelligence is used to identify the remotely sensed picture’s attributes like trees, roads, ponds, clouds, and big buildings so on

  • Line data signify the railway tracks, roads, and waterways or seaways
  • Point data signifies the location characters like buildings, churches, hospitals, schools, etc.,
