TIRUCHI: Techniques of land survey, photogrammetry, global positioning systems, airborne and satellite remote sensing, digital image processing, geographical information system and geovisualisation were covered during a three-day national workshop on `Geospatial Technology: Principles and Applications,' organised by the Department of Geography, School of Geosciences, Bharathidasan University, recently.

On the purpose of the workshop, A. Ganesh, Head of the Department, said applications of geospatial technology was vital for conservation of natural resources, dealing with the fundamentals of acquiring, processing, classifying, visualising and analysing spatial-referenced data of the earth and its surface features.

These applications were playing an ever-increasing role in conservation of natural resources what with advances in science and technology behind remote sensing making more practical the conduct of large-scale inventories that help in monitoring and evaluation of natural resources.

Geospatial technology, he said, was taking resource conservation planning and management to a new level. So much so that in 2004 the United States Department of Labor identified geotechnology as one of the three most important emerging and evolving fields along with nanotechnology and biotechnology.

The capacity of computers to process maps - both individually and along with tabular data - adds a new dimension to processing of information.

Presenting the Indian perspective, N. Sivagnanam of the University of Madras, observed that geospatial technology was still in its infancy, but was fast becoming a major element of the resources management and decision making sector.

Much of these efforts were concentrated amongst a limited number of government agencies and a smaller number of the private sector agencies, he said addressing the valedictory.

Mr. Sivagnanam released a book on `Computer Basics for Young Geoscientists' authored by Mr. Ganesh on the occasion.

About 50 delegates from various universities including University of Burdwan - West Bengal, Shivaji University - Maharastra, Periyar University - Salem and Kerala University - Trivandrum, benefited from the workshop.
