PhD Research Topics in Remote Sensing and GIS

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.

Innovative PhD Research Topics in Remote Sensing and GIS

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.

    • 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
