Geo Web Services
With the development in the Web/Internet Services of India, the digital communication medium has enhanced the capability of integrating GIS data with appropriate software application making them more accessible and reachable to wide range of users, planners and decision makers. Geo Web portals and Apps are emerging as perfect tools for GIS data access, analysis and transmission.
Internet has facilitated major changes in the GIS domain. It has led to online access to GIS data for visualization and query, Sharing of Data has been much fluent now, linking of real/near-real time data is being possible, Online transaction for data, data processing is possible. The most important advantage of this technology is "dynamic" nature of GIS.
Assam State Space Application centre in the state of Assam is one of the leading organization working in the field of Geo-Web services. Some of the popular Geo-Web services hosted by ASSAC are:
I. Bhuvan - Assam Node:
BHUVAN is an online geo-platform developed by National Remote Sensing Centre(NRSC),ISRO, GOI Hyderabad. It was released in 2009, which initially focused on image and map visualization services but has diversified over a period of time. As of 2018, more than 6000+ maps and OGC services, 64+ applications and 30 state portals have been configured and deployed live for:
1. Better utilization of the State specific Geo-spatial data and services
2. Data prepared by State Centre is made available on the Bhuvan Node Server
3. Bhuvan provides and hosts additional services on state related data
4. Bhuvan State Node is implemented for distributed load balancing of core geo-portal
II. NESDR - Assam Node
NeSDR is a Scheme sponsored by North Eastern Council/Ministry of DoNER , GOI through North Eastern Space Application Centre (NESAC). With a few objectives as under:
1. To create Spatial Data Repository (SDR) of NER
2. Facilitate data sharing & dissemination gateway for maximum utilization of Spatial inputs for various developmental planning activities or governance of NE region
3. GIS data cataloguing generated at different scales, different time period in different format by DOS/SRASCs
III. Crime GIS - Assam Police
Digital maps are the quickest means of visualising the entire crime scenario. The locations of crime events, arrests, etc. can be routinely displayed on maps. Crime mapping supports many forms of operational, tactical, investigative and strategic policing and crime reduction activity.
1. Data Visualization and Real time crime monitoring
2. Facilitating Search & Query by attribute,multiple attribute filtering
3. Report generation and proximity analysis
IV. RUSA GIS - Deptt. of Higher Education, GOA
The digital mapping of educational institutions along with the ward/village boundary, road access and major settlement provides the ground reality in terms of spatial and social coverage of institutes with respect to population density.
1. WEB GIS map with geo-points of Higher Educational Institutes
2. Space technology powered Dashboard for administrators
3. Dynamic data display on geo-point click
