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 now a days a very simple and easy process just like purchasing on any e-commerce portals.
Four simple steps will explain the acquiring process of satellite image.
- Select the interested area using polygon in shape file, 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 cart
There is variety of satellite images available on web-portals, provided and supported by many government and other agencies.
These satellite images are available in the paid form as ell as free of cost on web
portals.
Different web portal are defined below, from where one can search, preview and download satellite images.

The platform is
well-built but most of the data is for India only. This includes IMS-1
(Hyperspectral), Cartosat, Ocean Sat and Resource Sat – which are all Indian
satellites.
