As defined by the USGS , this is the science of acquiring information about the Earth’s surface without being in direct contact with it. This involves detecting reflected or emitted radiation, usually from satellite or aerial platforms.
Once data is acquired, GIS provides the "intelligence" to interpret it. A GIS is a computer-based system designed to capture, store, manipulate, and analyze spatial and attribute data. Bhatta emphasizes that the strength of GIS lies in its spatial data models—such as raster and vector—which allow for complex geospatial analysis. By integrating satellite imagery with Global Navigation Satellite Systems (GNSS) like GPS, GIS allows for precise mapping and real-time monitoring of earth resources. Integrated Applications and Future Trends
Digital image processing, visual interpretation, and photogrammetry. Part II: GIS and Geospatial Analysis Spatial and attribute data models. Geospatial analysis techniques and metadata concepts. Planning, implementation, and management of GIS systems. Supplementary Topics : The book also explores Global Navigation Satellite Systems (GNSS)
This approach makes the text timeless. While software versions change every year, the fundamental physics of electromagnetic radiation and the geometry of map projections remain constant. By focusing on these enduring principles, Bhatta ensured his book remains relevant even as technology advances. remote sensing and gis basudeb bhatta pdf

Remote Sensing and GIS by Basudeb Bhatta: A Comprehensive Guide
It opens with a narrative on the history of remote sensing and the Indian Space Program The Process (The Middle): A GIS is a computer-based system designed to
Remote sensing is the process of collecting data about an object or area without making physical contact. This is achieved through the use of sensors mounted on aircraft, satellites, or other platforms. The sensors detect electromagnetic radiation reflected or emitted by the object or area, which is then transmitted to a receiving station for processing and analysis. Remote sensing has a wide range of applications, including:
: Use of DBMS and SQL for handling attribute information and the importance of metadata (data about data) for quality control.
In the rapidly evolving landscape of geospatial technology, the challenge for any textbook is to remain comprehensive without becoming quickly dated. Bhatta's work navigates this expertly. It is specifically designed to serve as a basic text for undergraduate courses in fields like civil engineering, geoinformatics, geotechnical engineering, and environmental engineering. Its scope, however, extends equally well to meet the requirements of courses in geological science, environmental science, geography, geophysics, and disaster management.
