Dr. S. Dutta, SAC Ahmedabad presented the application of IRS P4 and Radarsat data for assessment of damage due to super cyclone of Orissa in October 99. Okhimath landslides and its impact assessment on the Madhyamaheshwar and the Kaliganga watersheds using high resolution IRS 1C/1D data was presented by Dr. M. M. Kimothi, SAC Ahmedabad. He has used temporal IRS data to map changes in the general landuse of the area. Detailed studies slope, aspect geology, landslides were carried out to assess impact of landslide in Okhimath region of Uttar Pradesh.

Dr. Vimal Kumar (GSI, Shillong) using multi date satellite data identified hazard prone areas in Bhramputra valley Assam. Major hazards identified by him in the valley are floods, river bank erosion, water logging, seismic activities and river migration.

Modeling of erosion intensity in Himalayas was demonstrated by A. K. Joshi (RRSC, Nagpur) using GIS and remote sensing data for preparing erosion intensity map of Himalayan region. Multidate remote sensing data showed changes after treatment in some of the watershed and found that the erosion has reduced in some areas due to such treatment.

Technical session on Geomorphology, Hydrology and Snow. was chaired by Professor R. S. Chaturvedi (Ahmedabad) and Dr. K. S. Rao (CSRE, Mumbai). In this session Dr. B. J. Choudhury (NASA, USA) presented an invited talk on the application of satellite data to evaluate evaporation and vegetation productivity of selected river basins of different parts of the world. The application of remote sensing data in determining various surface and meteorological parameters in evaluating evaporation have been illustrated.Mr. S.K. Ambast (IIT Delhi) presented a contributory paper and illustrated the importance of hydrological modeling with remote sensing in irrigation system management.Dr. P.C. Joshi (SAC, Ahmedabad) presented the utility of IRS P4 MSMR data in retrieving surface specific humidity over the Arabian oceanic region.

The industrial presentation was chaired by Ravi Gupta, managing Director, GIS Development. Various industries ROLTA, OPTIMA, C-DAC, Pune, Sierra Optima, National Remote Sensing Data Center made their presentation and gave detailed information about the softwares and their products supports for various applications to users in India.

In the evening of the first day November 21, 2000, Dr. Govind B. Pant, Director, Indian Institute of Tropical Meteorology, Pune gave Vikram Sarabhai Memorial Lecture on Weather Based Natural hazards and their Management. Dr. Pant gave an account of the role of Weather on natural Hazards like Drought, Floods, Tropical cyclones, Thunderstorms, Hail storm, Dust storms, Fog, haze and Mist. Looking at the huge less of life and properties from natural Hazards, Dr. Pant stressed the need of disaster management for advance warning, rescue and relief.

The second day of the symposium was started with the special session on Students Presentation which was well attended and unique session to give chance to the young students to make their presentations. This was the first time in the history of the Indian Society of Remote Sensing to see the overwhelming attendance by the Indian students. 48 Post graduate and Research students from research, academic, IITs and Universities have attended the Symposium and made oral and poster presentations. There were six presentations made by students working presently at SAC, Ahmedabad, BIT Pilani, IARA, New Delhi, IIT Kanpur and other Universities. These students also display their posters for two days. This special session was chaired by Professor Manfred Buchroithner (Germany) and Co-Chaiperson was Professor Sonyo Mukai (Kinki University, Japan). The Chairman and Co-Chaiperson appreciated the efforts made by Indian students in the field of remote sensing and GIS.

The technical session on Air Pollution was chaired by Dr. S. Mukai, Kinki University, Japan and co-chaired by Dr. S. K. Subramanian NRSA, Hyderabad. In this session, Dr. S. Mukai presented an invited paper giving detailed account of aerosol retrieval techniques using various remote sensing data over ocean and land. Important area of polarization and radiance in the visible and NIR Wavelength were stressed. A special algorithm was presented by Dr. Mukai in aerosol retrieval with lookup table method. The importance of ground based measurement in validity POLDER satellite data over southern Indian ocean, was also presented. Dr. K. V. Prasad (NRSA, Hyderabad) presented his work related to Trace Gas Emission from Biomass burning of secondary mixed deciduous forest estimates from satellite and ground based measurements in the area of Eastern Ghats of Andhra Pradesh. Use of IRS-P4 OCM data and ground truth data to quantify a few trace gases during pre and post burning was presented. Different component of biomass combustion have been calculated and that has been correlated with the satellite data, which was found to give good results.

The technical session on Forest and Agriculture was chaired by Dr. S. D. Naik (SAC, Ahmedabad) and co-chaired by Dr. N. S. Mehta (SAC, Ahmedabad).In this session six contributed papers were presented. Ms. Indrani Chaudhary (SAC, Ahmedabad) demonstrated the use of Radarsat data acquired in 24 days repeat cycle in monitoring, different stages of rice crop growth. Dr. B. M. Singh (INRIMT, Dehradun) showed the utility and cost effectiveness of IRS III and PAN data in sodic land mapping of Uttar Pradesh. Mr. M. S. Yadav (RSAC, Lucknow) presented the application of Multi date multi stage monitoring of sodic lands in a part of Pratapgarh District of Uttar Pradesh using remote Sensing and GIS. Vegetation Detection through Remote Sensing in extreme Arid zone was presented by Mr. S. Kumar (CAZRI, Jodhpur). He brought out the limitations of remote sensing techniques for vegetation mapping in particular in the desert land of Western Rajasthan.
