Tamil Nadu Geographical Information System – TNGIS
- Many departments in the State have been extensively working on GIS and Remote Sensing Technology platforms and preparing huge volumes of datasets of various scales for the State.
- Due to a lack of coordination, there is no standardization of the data resulting in duplication of activity taking place.
- Sharing of maps among the departments was not in practice.
- To overcome the above situation and to have a unanimous entity to monitor and streamline the spatial data it was proposed to develop State Spatial Data Infrastructure (SSDI) in the state through TNGIS by the State Level Coordination Committee (SLCC) functioning under the Chairmanship of the Chief Secretary, Tamil Nadu.
OBJECTIVES
- Development and implementation of Standardised District and State Level GIS applications for planning and monitoring processes in all the districts of Tamil Nadu using natural resources, socio-economic, demographic and agro-economic data from different sources
- Generating standards for spatial data
- Enable sharing and access of spatial datasets through appropriate Government Orders.
- To avoid duplication of efforts and wastage of resources in acquiring spatial datasets from GoI agencies.
- Creating a Spatial repository and enabling access to vital datasets through Geo-Spatial Web Services with the application.
INSTITUTIONAL FRAMEWORK
- State Level Coordination Committee (SLCC) is already functional under the Chief Secretary
- NIC to be assigned the role of Implementing Agency
- Formation of Technical Committee
- Drawing and ensuring that standards are complied with by all Departments
- Identifying and recommending authentication on various layers – for public or Departmental access only.
- Common Coding system to be followed in various sectoral Datasets (Spatial / Non-spatial)
- Time-to-time assessments on the needs (resources/data/others) and providing solutions to acquire the same.
Role of Stakeholder Departments
- Generating and sharing of Spatial and Non-spatial datasets as per the standards and guidelines suggested by TNGIS technical team and Map policy.
- Nominating / Deputing nodal officers in each department identified to ensure regular updating of data (Spatial and Non-Spatial)
- Ensuring the web-based data services and regular updation.
Role of TNeGA-Nodal Agency
- Overall Coordination among all the Stakeholder Departments in the State Ensure necessary infrastructure and logistics support to the TNGIS development Team & Stakeholders, Capacity Building among Departments to ensure progress and sustenance of the whole initiative.
- Building necessary infrastructure at TNSDC, Custodian of Spatial Layers and undertaking security audit of Web based GIS application and updation.
Implementing Agency (NIC)
- Design and Development of the Web Based System.
- Provide all technical support to the user Departments in generating spatial data as per standards.
- Imparting / handholding staff of the state stakeholders and preparing user manual.
- Develop a Web based GIS system (primarily to cater G2G and partially G2C services at a later stage) providing Geo Spatial services to resource departments
- Leveraging the use of using Service Oriented Architecture so that all Systems interact through Web Services
- Enabling a Decision Support System for resources departments and District Administrations.
