Physicochemical assessment of water quality with respect to Remote sensing and GIS techniques - Advances in Pure and Applied Chemistry

This paper published in the journal Advances in Pure and Applied Chemistry, sheds light on the serious problem of the increasing levels of pollution of water bodies in India due to escalating populations, urbanisation and increasing economic activity and highlights the urgent need to conduct effective and efficient water quality assessment measures. The paper highlights the limitations associated with the conventional water quality assessment methods and discusses the recent advances in Remote Sensing (RS) and Geographical Information System (GIS) techniques and their relevance as promising alternatives for effective water quality assessment to the conventional water quality assessment methods.Read More

Impact assessment of urbanization in Indian city of Ranchi – A report in Geospatial World

This report from Geospatial World presents an impact assessment of urbanization in the Indian city of Ranchi. Patterns of spatial and temporal urban changes have been analysed efficiently using spatial and temporal technologies such as Geographical Information Systems (GIS) and Remote Sensing (RS) along with collateral data such as Survey of India (SOI) maps, etc.

Ranchi

In order to study the change of spatial extent of growth and infrastructural facilities, SOI toposheet number 73 E/7 along with IRS PAN with a resolution of 2.5m, LISS-III and LANDSAT-TM was used to generate different layers of years 1972, 2004, 2006 and 2010 respectively. The census of the city was integrated with the above mentioned data to identify the elements at risk associated with different forms of urban hazards.
