         1. Project Title - An assessment and impact of urbanization in South Delhi on environmental quality and disaster management using remote sensing and GIS
Funding Agency - DST under women scientist scheme
Value- For Rs 10,93,000/-
Status/Period - Completed (2015-17)
Brief Summary -The work involves an assessment of growth of urbanisation in south Delhi as assessed using temporal IRS data and its impact of certain measurable environmental parameters and recommendations for disaster management using GIS
Major Highlights/Objectives - To examine the impact of urbanization on the land cover / land use changes, To determine the trend, nature, rate, location and magnitude of land use /land cover change, To forecast the future pattern of land use land cover in the area, To analyze the relationship between urbanization and emerging land use pattern in South Delhi city, To assess the changing pattern of urbanization and to evaluate its impact on urban environment both qualitatively and quantitatively, To analyze various possible disasters in South Delhi, India and to assess the impact of urbanization on Disaster Management and Mitigation in the area
Progress : Temporal data analysis to assess the growth of urbanization is completed
         2. Project Title - Detection and Identification of engineered surfaces and Objects using Hyperspectral data
Funding Agency - - DST under Networked Hyperspectral Project
Value- For Rs 35,02,400/-
Status/Period - In Progress (2016-19)
Publications - Communicated in Peer-reviewed Journals
Brief Summary - The work involves an development of spectral libraries in an urban environment for various engineered surfaces and Objects and development of algorithms for their detection and identification using spectral matching algorithms
Major Highlights/Objectives - Study and selection of certain relevant engineered surfaces and objects to be covered which may include road and run way surfaces, steel structures and objects such as military tanks, aircrafts etc, Generation of hyperspectral spectra containing these selected engineered surfaces, objects and targets, obtain aerial/satellite based hyperspectral data in respect of these targets, carry out its detection using spectral matching algorithms, anomaly detection algorithms and independent component analysis and compare their performances using an ROC curve analysis, Identify set of most appropriate spectral bands and algorithms for detection and identification of these selected engineered surfaces, objects and targets.
Progress : The project shall use hyperspectral data acquired by AVIRIS sensor under SAC ISRO and JPL NASA joint campaign which has since been completed and the PI too was part of it and certain ground truth data too has been collected.
         3. Project Title - Mapping Impervious Surfaces from Temporal Multi-sensor Multi-resolution Data and its Area Estimation Using Super resolution
Funding Agency - SAC, ISRO, Ahmadabad
Value- Rs 20 Lac
Status/Period - In Progress (2017-19).
Publications - Communicated in Peer-reviewed Journals
Brief Summary - Globally, there is rapid urbanization and various UN estimates predict a possible growth of almost 84% in urban areas with an increase in total population size of 10 billion by the year 2050. Traditionally, ground surveys and aerial photo interpretation have been the most accurate methods of mapping of impervious surfaces and its area assessment but they are not time effective. Availability of finer resolution spectral, spatial and temporal data can facilitate cost effective mapping and monitoring of changing impervious surfaces which in turn can assist in various aspects of urban planning, management of surface runoff/flooding and in monitoring the environment
Major Highlights/Objectives - The aim of the proposed work is to develop alternative approaches and strategies for identification using spectral libraries, mapping and area estimation of impervious surfaces. It is also proposed to refine the estimated area of the identified impervious surface using super resolution methods/techniques and to develop approaches for assessment of growth in impervious surfaces using temporal, multi-sensor and multi-resolution data
Progress : The project has just commenced and studies on super resolution algorithms are in progress
