- Abstract
Indian Earth Observation (EO) programme since its inception has been application driven. It has evolved from experimental satellites, operational satellites to present generation of theme specific satellites. Theme specific EO satellites have been categorized in three categories \u2013 Land, Cartography and Ocean and Atmosphere theme observation satellites. Indian EO capabilities has increased manifold. Improvements are not only in spatial, spectral, temporal and radiometric resolution but also in their coverage and valve added products. In the coming 10 years, India has planned more than 20 satellites carrying varieties of capabilities and complexities. It will have microwave, hyperspectral, stereo viewing, viewing from geo-synchronous platform etc., which will fulfill the present and future gap areas in EO applications. A variety of data products will be obtained from multiple missions for multiple themes. A complete standardization is sought to acquire, manage, process and disseminate these datasets to meet the various application requirements and user needs, like global change applications mapping and cartographic applications, natural resources and environmental management applications, disaster management etc. The user of EO is concerned with the data products, which link space technology to user. There has been a paradigm shift in the concept of data product - from image to information to products and services. In order to realize these missions and derive maximum benefits from their user, a number of areas, related to ground segment need to be addressed like multi-mission acquisition and processing, effective delivery mechanisms, real time web-based services, mission oriented outreach activities, etc. Spatial information - satellite images and maps forms the foundation and basis for most planning and implementation of developmental activities, infrastructure development, disaster management support, environmental monitoring, natural resources management, rural development, business and many other national activities. Hence, standardization is must in systematic spatial dataset creation at various scales derived from satellite images. This calls for standardization for the total process of spatial information generation upto its final delivery that enables uniformity and flexibility in mapping and GIS database organization. These standards enable technologies - imaging and GIS applications - thematic mapping, services and outputs etc. to work together, increase interoperability, brings systematization and automation of mapping and GIS so that it will generate the actionable products and services. Again, for dissemination of spatial data and application services, effective delivery mechanism need to be worked out which will be on real time basis, easily accessible and faster to achieve the critical needs like weather forecasting, disaster monitoring etc. Standardisation of activities in Indian EO system has been an on-going activity with tune to international efforts of CEOS, ISPRS, GSDI, etc. The present paper brings out the various elements of standardization in the area of Indian EO satellites data, various products, maps, applications, database organization, delivery mechanism and archival system.
