Basudeb Bhatta's Remote Sensing and GIS is a cornerstone text for understanding Geoinformatics. For the best learning experience—especially regarding the mathematical formulas and high-resolution satellite images—an official copy or library access is highly recommended over low-quality PDF scans found online.
Title: Remote Sensing and GIS for Land Use/Land Cover Changes Author: Basudeb Bhatta Journal: Journal of the Indian Society of Remote Sensing Year: 2010 Volume: 38 Issue: 2 Pages: 167-175
Abstract:
Remote sensing and GIS have become powerful tools for studying land use/land cover changes. The present study aims to assess the land use/land cover changes in the study area using remote sensing and GIS techniques. The study area, Kolkata metropolitan area, has undergone rapid urbanization and land use changes in recent years. Multi-temporal satellite images of 1980, 1990, 2000, and 2008 have been used to study the land use/land cover changes. The images have been classified using a supervised classification technique. The results show significant changes in land use/land cover patterns over the study period. The urban area has increased significantly, while the agricultural land and vegetation cover have decreased. The GIS analysis reveals that the changes are concentrated in the areas with high population density and accessibility.
Introduction:
Remote sensing and GIS have become essential tools for studying environmental changes, including land use/land cover changes. Remote sensing provides a synoptic view of the Earth's surface, while GIS allows for the analysis and integration of spatial data. The study of land use/land cover changes is crucial for understanding the impact of human activities on the environment.
Methodology:
The study area, Kolkata metropolitan area, has been selected for the study. The area has undergone rapid urbanization and land use changes in recent years. Multi-temporal satellite images of 1980, 1990, 2000, and 2008 have been used to study the land use/land cover changes. The images have been classified using a supervised classification technique. The classified images have been then analyzed using GIS techniques to study the changes in land use/land cover patterns.
Results and Discussion:
The results show significant changes in land use/land cover patterns over the study period. The urban area has increased significantly, while the agricultural land and vegetation cover have decreased. The GIS analysis reveals that the changes are concentrated in the areas with high population density and accessibility. Google Books Preview: Google Books often allows you
Conclusion:
The study demonstrates the utility of remote sensing and GIS techniques for studying land use/land cover changes. The results of the study can be used for planning and management of land resources.
