Kohima, February 16 (Mexn): Remote sensing and geographical information system (GIS) techniques can be effectively utilized for the mapping of all road networks and generation of these databases for information system in Nagaland. As of now, there is no proper inventory or mapping of road network or database for management of road for the entire state of Nagaland in GIS environment. This was stated in the publication of ‘Science and Technology Intervention in Nagaland’ published by The Nagaland Science & Technology Council (NASTEC).
NASTEC’s objective is to prepare road maps at district level and block level using various datasets and to prepare road information system for both the levels in the form of Atlas. The database of road information system include all types of road viz. National highways, state highways, other district roads, all major road, footpath and block/circle roads. It also includes other amenity layers like health, bank, educational institutions, fire services, post office, transportation, important tourist places, government and private establishments etc. The various important amenity layers prepared using GPS include - layers on medical health centre, layers on education sector and other layers include bank, transportation, tourist spot and government and private sector officers and institutes.
The spatial information is extracted from IRC Cartosat- I & II, GPS and other secondary sources. The non- spatial data are also collected using GPS for integration with the spatial layers.
