Non spatial Database 2001 Census Data (part I and part II) Samanya Mahiti data – 21 sectors -357 fields (Infrastructure & Developmental activities-Habitation wise) – Part of the data has been integrated. District line department data
Development of Karnataka GeoPortal • To develop a web based Geo Portal to acquire, process, store, distribute and improve the utilization of geo spatial data • Data clearing house - Gateway for spatial data generated by various agencies in the State. Karnataka Geoportal
SDI Spatial Data Infrastructure (SDI) is the collection of technologies, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data. Karnataka Geoportal
Development of KSSDI Portal • Inventory of databases • Functional requirements of website/portal • Notification of Expression of Interest (EOI) • Pre-bid meeting with Industry/agencies • Preparation of Request for proposal (RFP) • Technical bid (scope of work) • Financial bid (hardware/software/networking/development etc.) • Invitation to bidders – RFP • Evaluation of technical bids • Short listing of bidders • Evaluation of financial bids • Identification of bidder for implementation • Technical committee for monitoring project implementation • Stakeholders meeting – formulate policies/standards Karnataka Geoportal
Stages of Portal development • Requirement analysis • Real world object catalogue • Conceptual Data Model • Centralized database • Publishing metadata • Creation of Geo-portal • Customization of software for creation of Geo-portal • Security system to handle data, identity & network • Testing of the Geo-portal/ database/ services • Final deployment of the complete system • Training • User acceptance testing • System maintenance for three years Karnataka Geoportal
Karnataka GeoPortal Services: • Map viewer - Web Map Service (WMS), • Product catalogue/metadata - Catalogue Service on • Web (CS-W), • Services specific service/ feature data sets - Web Feature • Service (WFS), • Simple Applications (Query based decision support) • Coverage services/images - Web Coverage Service (WCS) • Search and Discovery • Help/support Karnataka Geoportal

Real World Object Catalogue Layer/Dataset – Real World Object Properties KSSDI Real World Object Catalogue Comprises • Hierarchy and Classification of Datasets: • Real World Objects: Based on the hierarchy, the datasets are identified as the real world objects. Each dataset is categorized as a real world object defining its type, category, scale, definition, source and finally its attributes are designed for the future use.

Karnataka GeoPortal’s – Home Page • On Login into the Geo Portal, the user have access to the various modules of the SDI.
Karnataka GeoPortal’s – Map Viewer • Geo Portal Map Viewer module by default displays State Division and District Boundaries • The Layer Tab on the left pane displays the list of layers that can be made visible at various map scales. • User also have the ability to switch ON or OFF layers by using the Eye icon against each layer. • The General Map Viewing tools available are: Zoom, Pan, Full view, Previous and next view, Identify, Measure, Refresh and Load context. It also provides the scale bar, X Y coordinates, SRS (Spatial Reference System) and Over View Map display along with Google Map layer display.
Karnataka GeoPortal’s – Map Viewer • Add Layer Tab allows user to search for the available services through “Key Word Search” or “Spatial Extent ” using the Select Tool from the Toolbar. • The Resulted services will be displayed and by clicking “View on Map”, the selected layer gets displayed on the current Map Viewer. • Note: The current map displays the Division & District boundary with the State National Highway Layer resulted in the search above.
Karnataka GeoPortal’s – Map Viewer 3 • The Query Module provide option to query on attributes, spatial or combination of them to generate desired results. • The Application query sub module can be used to create and store commonly used queries that are regularly used for planning and decision making purpose. • Note: The current map viewer shows the Query on District Layer, Highlighting the districts with SC Population greater than 30%.
Karnataka GeoPortal’s – Map Viewer 25000 The Attribute Query Sub Module provides the ability to select multiple layers with or without spatial join and operators with input values to generate results and view them too on map. Note: The current map viewer shows the Query on District Layer, Highlighting the Districts with TOTAL ST POPULATION > 25000.
Karnataka GeoPortal’s – Map Viewer The Export module allows the user to select a specific layer for export to GML and SHAPE file format. Note: The above screen shot shows Export of District layer to GML.
Karnataka GeoPortal’s – Catalog Product Catalogue allows user to search the Published Web Services (WMS/WFS/WCS) in the KSSDI Data Repository. It presents the Metadata of the selected Layer (NSDI Metadata Standard 2.0). Also allows a user to all the layers to cart.
