How to Acquire Remote Sensing Data

Remote Sensing Data/Satellite Image Download Portals:

Satellite image is main source and input data for remote sensing studies. These input in the form of satellite image can be also used in GIS database generation as well as for analysis in GIS environment

So acquiring or ordering satellite images is nowadays a very simple and easy process just like purchasing on any e-commerce portal. 

Four simple steps will explain the acquiring process of the satellite images.
  • Select the interest area using polygon in shapefile, coordinates, or city/location name
  • Select the type of satellite image
  • Browse the searched image and check the image quality 
  • In the last download/order the satellite image through the cart
There is a variety of satellite images available on web portals, provided and supported by many government and other agencies.
