Welcome to the Odisha Spatial Data Infrastructure (OSDI). The Geospatial Clearinghouse, was established to disseminate GIS datasets available with various government agencies in ODISHA and to provide access through the Odisha Spatial Data Infrastructure (OSDI) Geoportal. The Odisha Spatial Data Infrastructure (OSDI) is an established node of the National Spatial Data Infrastructure (NSDI). Hosted by the Odisha Space Applications Centre (ORSAC). Odisha Spatial Data Infrastructure (OSDI) aims to position itself as an essential instrument to support decision-making through the use of geographic information.
The OSDI Geoportal provides easy and convenient ways to search, discover and use geospatial data resources. The primary goal of the OSDI Geoportal is to improve access to Odisha state geographic data portfolio, and expand the creative use of those data resources. The OSDI Geoportal strives to increase information transparency, and is committed to creating an open environment for accessing important government derived geographic data. The benefits derived from Geoportal will encourage information sharing, and promote efficiency and effectiveness in providing individuals and organizations timely and accurate geographic information for better and more informed decision making.
OSDI aims towards facilitating and co-coordinating the exchange and sharing of spatial data among the stakeholders in the state of Odisha, thus creating an information highway and facilitating smooth transaction and integration of sophisticated geospatial data sets. OSDI operates on a GIS database of data layers containing important information such as administrative boundaries, street centerlines, landuse, hydrology, forestry, cadastral and others.
We encourage department contributions, participation, and feedback in making the Odisha Spatial Data Infrastructure (OSDI) Geoportal and clearinghouse a dynamic and robust resource. If you have GIS datasets, projects you would like to showcase or other GIS-related information that might be useful to GIS users, please contact us to send the information. Let us know what resources you would like to see on the site and how we can make the site more useful to you.
Search functions are the major means through which users discover geospatial resources in a SDI. Here, we offer the user with two types of search functions.
Text-based Search is similar to Web search engines, in which a user types in some keywords and receives the results based on the matched text.
The text-based search enables general users, especially the users who are unfamiliar with a GIS, to find geospatial resources in a way similar to how they would use a general search engine, such as Google. However, it can be challenging to identify the suitable keywords, or the Keywords may not accurately describe the geographic areas that the user is interested in.
Map-based search allows users to find geospatial resources by interacting with a map, and a user can pan, zoom in and out, and draw polygons to specify their areas of interest.
The map-based search, on the other hand, provides convenience for the users who are already familiar with a map interface, and allows users to specify geographic locations in a more accurate manner (e.g., by drawing polygons). However, not everyone feels comfortable of using a map‐based interface. Geoportals often offer both search functions to complement the two and accommodate the needs of different users.
The Open Geospatial Consortium (OGC), an international voluntary consensus standards organization, originated in 1994. In the OGC, more than 500 commercial, governmental, nonprofit and research organizations worldwide collaborate in a consensus process encouraging development and implementation of open standards for geospatial content and services, sensor web and Internet of Things, GIS data processing and data sharing.
Most of the OGC standards depend on a generalized architecture captured in a set of documents collectively called the Abstract Specification, which describes a basic data model for representing geographic feature.
The following are few OGC Standards that OSDI follows.
WMS – Web Map Service: A Web Map Service (WMS) is a standard protocol for serving (over the Internet) georeferenced map images which a map server generates using data from a GIS database.
WMTS – Web Map Tile Service: A Web Map Tile Service (WMTS) is a standard protocol for serving pre-rendered georeferenced map tiles over the Internet.
WCS – Web Coverage Service: The Open Geospatial Consortium Web Coverage Service Interface Standard (WCS) defines Web-based retrieval of coverages – that is, digital geospatial information representing space/time-varying phenomena. A WCS provides access to coverage data in forms that are useful for client-side rendering, as input into scientific models, and for other clients.
WFS – Web Feature Service: The Open Geospatial Consortium Web Feature Service (WFS) Interface Standard provides an interface allowing requests for geographical features across the web using platform-independent calls.
WFS-T - A transactional Web Feature Service (WFS-T) allows creation, deletion, and updating of features.
WRS - The Web Registry Service is a software component that supports the run-time discovery and evaluation of resources such as services, datasets, and application schemes.
WPS – Web Processing Service: The OGC Web Processing Service (WPS) Interface Standard provides rules for standardizing how inputs and outputs (requests and responses) for invoking geospatial processing services, such as polygon overlay, as a web service. The WPS standard defines how a client can request the execution of a process, and how the output from the process is handled. It defines an interface that facilitates the publishing of geospatial processes and clients’ discovery of and binding to those processes. The data required by the WPS can be delivered across a network or they can be available at the server. WPS can describe any calculation (i.e. process) including all of its inputs and outputs, and trigger its execution as a web service. WPS supports simultaneous exposure of processes via HTTP GET, HTTP POST, and SOAP, thus allowing the client to choose the most appropriate interface mechanism. The specific processes served up by a WPS implementation are defined by the owner of that implementation. Although WPS was designed to work with spatially referenced data, it can be used with any kind of data.
Data is published from various departments such as ORSAC, Forestry, NIC India and other sources are available in WFS, WCS, WMS, WMTS and WMPS. The RoR (Right of Registry) information is available with links to respective cadastral data.
Geography Markup Language provides the basis for domain- or community-specific "Application Schemas", which in turn support data interoperability within a community of interest. Application schemas are normally designed using ISO 19103 conformant UML.
In order to expose an application's geographic data with GML, a community or organization creates an XML schema specific to the application domain of interest (the application schema). This schema describes the object types whose data the community is interested in and which community applications must expose. For example, an application for tourism may define object types including monuments, places of interest, museums, road exits, and viewpoints in its application schema. Those object types in turn reference the primitive object types defined in the GML standard.
Spatial analysis is how we understand our world— mapping where things are, how they relate, what it all means, and what actions to take.
Spatial analysis is a diverse and comprehensive capability that includes the simple visual analysis of maps and imagery, computational analysis of geographic patterns, finding optimum routes, site selection, and advanced predictive modeling. This process happens every day in the human brain. However over the last four decades, our ability to solve complex spatial problems has grown exponentially with technologies that include global positioning systems, real-time sensors, navigation systems, and most important, GIS.
The taxonomy of spatial analysis includes six high-level categories that classify and group related analytical questions.
OSDI Geoportal provides following tools,
Routing: Any line feature, such as a street, highway, river, or pipe that has a unique identifier.
Chart based analysis: A chart is a graphical representation of tabular data. Visualizing data through charts helps to uncover patterns, trends, relationships, and structure in data that may otherwise be difficult to see as raw numbers in a table.
Spatial query builder: A query allows you to retrieve information from source data by executing a predefined query.
Buffer based analysis: Buffering usually creates two areas: one area that is within a specified distance to selected real world features and the other area that is beyond. The area that is within the specified distance is called the buffer zone. A buffer zone is any area that serves the purpose of keeping real world features distant from one another.
In a GIS Application, buffer zones are always represented as vector polygons enclosing other polygon, line or point features
Maps Gallery is a configurable application template that can be used to access a collection of maps, published documents, technical papers and other content cataloged in an OSDI Geoportal. Content organized in a gallery by Geographic region.
It inventories all the metadata information of the registered geospatial resources in a geoportal catalog service, which is an Open Geospatial Consortium (OGC) compliant CSW service.
Catalogue Service - Web, is a standard for exposing a catalogue of geospatial records in XML on the Internet (over HTTP). The catalogue is made up of records that describes geospatial data (e.g. KML), geospatial services (e.g. WMS, WMPS, WCS, WFS and etc.) and related resources. It defines common interfaces to discover, browse, and query metadata about data, services, and other potential resources.
