Download free satellite images of Indian Satellite using NRSC-Bhuvan website

Bhuvan portal is a platform created by National Remote Sensing Center of Govt of India to provide free satellite images of different satellite such as LISS-III, LISS-IV, Cartosat DEM etc. This portal also provide free classified and thematic maps. 
These satellite image can easily download by select and preview process. 

Open weblink: http://bhuvan.nrsc.gov.in/bhuvan_links.php

From this page go to top menu option – Open Data Archive

  • A new window will open after clicking on Open data Archive.
  • You need to make user id on this page so click to Login (on the extreme top right corner)
  • A new small window will open for login credentials, scroll down it and click on New User

  • Create login id by providing details such as user name, email id, first name, last name etc.

  • Go to click here to login and also an email sent to your email id, activate that email id and login in bhuvan portal through your login credentials.
  • After Login start searching satellite data of your study area by using below steps

  1. Select the area of which you need to download satellite images by providing Place name, Lat/long.
  2. Select category – Satellite/Sensor to download satellite images
  3. Select Sub Category- Name of satellite/Sensor is provided, so select as per need, as in this Resourcesat/LISS-III selected

4. After providing satellite/sensor details scroll down and go to Select Area- In that different options are provided to select area such as bounding box, mapsheet, tiles and interactive drawing.
  • Bounding box- in this you can provide extent of your study area.
  • Mapsheet- 50K toposheets no. of your study area.
  • Tiles- select by clicking on tiles in the right screen.
  • Interactive drawing- one can draw random polygon based on study area in the right screen to select tiles.
  • In this explanation tiles option is used and tiles are selected in right screen by clicking on the tile. For multiple selection of tiles use shift button.
Now scroll down and 


Selected tiles are visible in red color

5. Click on Next Button (In above Image)


Downloadable Images will display in left part of screen, one can download image based on year/date of pass by clicking on download option.

There are several methods through which height/elevation can be measured using satellite image and aerial photographs . In case of satellite image such as, Cartosat,  ASTER, Worldview I & II and others are used to create height or elevation data in the form of digital elevation model .  Aerial photography, LiDAR mapping are very common for creation of elevation data on higher scale/resolution for detailed study.  In the last article, relief displacement used to measure height of any object on earth surface. Here in this another method will be discussed to measure height of any given object on the earth surface. Parallax for Height Measurement using Aerial Photography Parallax Concept Photogrammetry is capable of measuring elevation of earth surface. Aerial photographs/stereo pair satellite images can be used to measure elevation differences through the use of parallax method.   New launched satellite are providing stereo pair satellite images images such worldview-2 etc.

Satellite Image Processing Satellite image processing include various steps and processes to make image ready for interpretation and classification . These processes are important on each step of image processing such as geometric correction, radiometric correction, enhancement , classification etc.  These processing methods are also depend on number of bands present in image as well as on spatial and temporal properties of satellite image . In this article some basic image processing tools are discussed using  Erdas Imagine. As data downloaded/purchased than there may be some basic operations need to perform for digital image processing . These tools may vary with data acquired, in general satellite data need to stack, subset, mosaic and re-project based on the project requirement and data availability. Layer Stacking: This process is primary process after acquiring satellite images as most of the satellite images are provided in different bands or layers , such a

Image Enhancement-Contrast Adjustment In the last article, learned about the basis concepts of image enhancement and importance of enhancement in satellite image processing .  Understand satellite image , especially DN values stores in each pixel  Process in Erdas Imagine to see DN values stored in pixels through viewer Image Info.  Adjustment of contrast of Image to improve quality  Image Enhancement Processes  In this article will move further to understand some more process can be used to improve quality of image. But this needs basic understanding of DN value and its range for all bands used in image stacking .   There are some enhancement process are available in all image processing software . Here will discuss enhancement functions of Erdas Imagine software .   After displaying a satellite image in viewer of Erdas,  click on Raster tool from menu bar of Viewer.  Click on Contrast  There Select General contrast   in that tool many contrast adjustmen
