Abstract: This research provides the rationale for approaching the applications of satellite
photogrammetry by integrating high resolution satellite stereo data. To start
with a brief overview of the background of photogrammetry and its emerging
scenario in India. Then introduced the paradigm on application of satellite
photogrammetry using a case study approach to understand the problem and
terrain applications in natural resources studies. The second part discusses
methodologies to achieve that approach by using high resolution satellite stereo
data for a number of applications.
Different case study approaches have been followed: including applications of
stereo data in disaster management i.e, flood management both natural and
manmade i.e, due to dam construction. Stereo data to explain or supplement
observed patterns of land- use and land-cover change; followed by its analyses
of spatially-explicit application in irrigation management including planning for
canal construction, its alignment and all; application in watershed management;
interpretations of spatial patterns of land use in terms of land use practices with
emphasis on its application in mining i.e, to assess the changes in the study area
over time. After a review of the literature, we propose an advantage of using
high resolution satellite stereo pairs to conduct integrated, place-based
research, planning and management of water resources and others.
For these studies, high resolution satellite imageries of half a meter resolution,
stereo pair of the images from which high resolution Digital elevation model and
ortho imagery has been created using data retrieved from satellites like
worldview1 and WorlView2,50cm respectively.
