OGC GIS VISUALIZATION WEB SERVICES

  Geographical Information Systems (GIS) introduce methods and environments to visualize, manipulate, and analyze geospatial data. The nature of the geographical applications requires seamless integration and sharing of spatial data from a variety of providers. To solve the interoperability problems, the Open Geospatial Consortium (OGC) has introduced standards by publishing specifications for the GIS services. OGC is a non-profit, international standards organization that is leading the development of standards for geographic data related operations and services. OGC has variety of contributors from different areas such as private industry and academia to create open and extensible software application programming interfaces for GIS. Our GIS Visualization Web Services are OGC compatible.

  GIS services, such as defined by the OGC, are part of a larger effort to build distributed systems, such as Grids, around the principles of Service Oriented Architectures (SOA).  Such systems unify distributed services through a message-oriented architecture, allowing loose coupling, scalability, fault tolerance, and cross-organizational service collections. Web Service architectures are a common implementation of SOA ideals, and Grid computing has converging requirements.   By implementing Web Service versions of GIS services, we can integrate them directly with scientific application grids.

 

Project Topics;
  • Creating WMS Client for the Geophysics Applications
  • Creating OGC-WMS providing visualization services over
    • HTTP GET
    • HTTP POST
    • and SOAP protocols
  • Chaining of GIS Visualization and Geophysical Application servers in SOA.
  • Streaming Video and Map Services
  • Collaborative WMS
    • Static Map Images
    • Streaming Video Maps -for the time series data.
    • Providing various video streaming formats for
  • Using high performance, fault-tolerant messaging middleware system, Naradabrokering, for the message exchange between distributed and chained GIS Web Services.
