WCS supports the networked interchange of multi-dimensional and multi-temporal geospatial data as “coverages” through the “getCapabilities”, “describeCoverage” and “getCoverage” interfaces. WCS provides intact geospatial data products encoded in HDF-EOS, NITF, and GeoTIFF to meet the requirements of client-side rendering, multi-valued coverages, and input of scientific models and other clients beyond simple viewers.

WFS supports the networked interchange of geographical vector data as "feature" which is described by a set of properties where each property can be thought of as a {name, type, value} tuple and at least one property is geometry-valued. The name and type of each feature property is determined by its type definition in its schema file. All feature data are encoded in Geographic Markup Language (GML) which is a kind of extensible markup language for support and storage of geographic vector data to meet the requirements of complex spatial analysis.

CSW supports the registry and discovery of geospatial information resources. It plays a "directory" role in the open, distributed Web service environment: providers register their capabilities using metadata, and users can then query the metadata to discover interesting information. See introduction and detail. Demo...

Rerojects a coverage in HDF Grid format to another projection. Currently it supports all the projections defined in GCTP. The parameters of request include the URL of source HDF file, target projection type, resampling method, bounding box and the 15 float type projection parameters defined by GCTP, and the result is a URL point to the target HDF file. See WSDL. Demo...

We have developed SOAP based Webservice interfaces(please follow this link to learn about SOAP) to many non-interactive functions of GRASS (Geographic Resources Analysis Support System) software. See this to learn how to construct BPEL Process using these services. See detailed services .

We develop 46 web services to manipulate raster, vector, process satellite image data. These Web Services are developed based on Geographic Resources Analysis Support System, commonly referred to as GRASS, which is an open source (GNU GPL'ed), image processing and geographic information system (GIS). See detail...

• BPELPower v1.0:
  • Based on the mainstream standards including BPEL, WSDL, WSIF, Xalan, Xerces, UDDI, AXIS, SOAP, JNDI, J2EE (servlets/EJBs/JSPs), Jetspeed (Portlets) and JMX. It runs on top of popular application servers, such as Tomcat, J2EE, JBoss, Weblogic and WebSphere. It now supports BPEL-based web service chain completely. It supports:
    • "deploy it". WSDL-based web services can be deployed in BPELPower, where their validations are checked.
    • "see it". WSDL-based web services can be displayed in BPELPower in different ways.
    • "try it". BEPLE-based web services chain can be executed in BPELPower dynamically. Different invocations (e.g., HTTP POST/GET, SOAP document/rpc, etc.) are well supported.
See detail at http://geobrain.laits.gmu.edu:8099/bpelasync.

Abstract model designer enables domain experts to use data types, service types and existing abstract models as basic components to construct abstract models, which represent the domain knowledge of the experts, in a clicking and dragging manner. The experts can choose to validate the abstract models and register those models into the Catalogue Service for Web (CSW), which will enable the abstract models available for later use. An abstract model can be instantiated and transformed into a concrete BPEL process, which can be executed in a BPEL engine (e.g. BPELPower ). See tutorial...
