GIS Development, in association with the Center for Science, Development and Media Studies (CSDMS) organized GRATICULE 2005 – the Annual International Conference on Surveying, Positioning and Locational Intelligence from 3rd to 4th October in Hotel Taj Palace, New Delhi. Remarkable developments have taken place in the field of global positioning technology over the last three decades. Reaching far beyond military application, the GPS and GLONASS satellites are today reliable providers of timing, positional and navigational information for uses as varied as wildlife monitoring, earthquake research, town planning, cadastral mapping, and precision farming and fishing. India too has taken the first step in this direction with Indian Space Research Organisation, ISRO initiating work on a Geostationary Orbit Augmented Navigation Technology Demonstration System – GAGAN-TDS. The conference was organized in this background.
