- 1. Unlocking the Power of Geospatial Data: An Introduction to the Open Geospatial Consortium Presented By Group D : Bikram Shrestha
- 2. Content : • Introduction • Importance in Geospatial Industry • OGC Services/ Protocols • OGC & the Future • Framework • Canclusion
- 3. Introduction : OGC • Open Geospatial Consortium • Global organization that develops and promotes open standard for geospatial data and services . • Non profit organization • 200+ Industry ,Government ,NGO and University
- 4. Importance in geospatial industry : OGC service came to existance to address the : • Need of interoperability in the geospatial industry • Standardization in the geospatial industry • For developing and promoting open standard • To facilates the seamless integration and sharing of geospatial information • For collaboration and adoption by the geospatial industry .
- 5. OGC Services/Protocols : 1. Web Map Service (WMS): Displays an image (gif, jpeg, png) of vector or raster data 2. Web Feature Service (WFS): Provides access to vector data (output in Geography Markup Language (GML)) 3. Web Coverage Service (WCS): Provides access to raster data 4. Catalog Services for the Web (CSW): Provides access to metadata of geodata and services 5. Web Processing Service (WPS): Provides access to remote GIS operations (for example Buffer, Distance calculation, Coordinate transformation) responses are standard-based messages.
- 6. WMS : Web Map Service • Displays an image (gif, jpeg, png) of vector or raster data • Standard protocol for serving georeferenced map images generated by a map server. • Output is static map • Eg Google map • Limited or no support spatial queries .
- 7. WMS : Web Map Service
- 8. WFS : Web Features Services • Provides access to vector data (output in Geography Markup Language (GML)) • Return the actual geographic data that comprise the map images. • Output is feature data ( Attributes & Geometry ) • Advanced spatial filtering & querying.
- 9. WFS : Web Features Services
- 10. Web Coverage Service (WCS) : • Serving and exchanging geospatial data in raster format. • Allows users to access, subset, and transform geospatial data in a variety of formats including GeoTIFF, NetCDF, and HDF. • Serving and accessing multi-dimensional geospatial coverages over the web.
- 11. Catalog Services for the Web (CSW) : • Type of web service that allow users to discover, query, and retrieve metadata about geospatial data resources. • Provides access to metadata of geodata • and services
- 12. Web Processing Service (WPS) : • Provides access to remote GIS operations • ( For example Buffer, Distance calculation, Coordinate transformation) responses are standard-based messages.
- 13. OGC & The Future : • The forefront of shaping the future of the geospatial industry with the rapid advancement of technology • Drive the industry forward and unlock its full potential • Addressing some of the biggest challenges facing the world today, such as climate change, urbanization, and natural disasters • OGC is committed to using geospatial data and technology to create a better future for everyone.
- 15. Canclusion : • In conclusion, the Open Geospatial Consortium (OGC) plays a crucial role in the geospatial industry by developing and promoting open standards for geospatial technologies. • OGC standards ensure interoperability between different systems and enable collaboration across organizations and sectors. • By using OGC standards and services, users can benefit from increased efficiency, reduced costs, and improved decision-making.
