How to Acquire Remote Sensing Data

Posted by

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.

Bhuvan Indian Geo-Platform of ISRO
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.

Height Measurement by Aerial Photographs based on Concept of Parallax

Posted by

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.

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 adjustment

GIS (Geographical Information System) Geographical Information System (GIS) is an integrated tool, capable of mapping , analyzing, manipulating and storing geo-spatial data in order to provide solutions to real world problems (For example: logistics, e mergency evacuation, and tax assessment, real estate analysis etc.) and help in planning for the future. Importance of GIS GIS is a computer-based tool that allows you to integrate different kinds of geographic information such as satellite images , aerial photographs , digital maps, and global positioning system data (GPS), along with associated tabular database information. GIS not only helps you to examine and analyze geographic information at different levels of detail; but also allows the user to perform statistical analysis or spatial analysis . Predictions for the future can also be done using GIS models in the areas of land-use change , urban sprawl , habitat loss, and to predict seismic activity precisely . Componen
