GeoQoS

Description
GeoQoS is tool for QoS-aware geoprocessing. It can evaluate the quality of geoprocessing services with users’ feedback and other quality factors including availability and reliability. QoS for each geoprocessing services can be visualized in a Virtual Globe environment to facilitate service selection. Users can set QoS constraints for processing nodes in geoprocessing workflows, and then optimize workflows with constraints satisfaction. The tool has been implemented as an extension to an existing geoprocessing modeling tool—GeoJModelBuilder.

Features about GeoQoS
GeoQoS is being developed to provide more evaluation models and optimization algorithms. In addition, interactive and user-friendly GUI are being investigated to facilitate the use of GeoQoS. We will investigate more cases on process qualities to help standardize the quality of geoprocessing services. The experience in developing GeoQoS also helps enhance the previous work on semantics-based service discovery, chaining, and geoprocessing modeling by fully considering data, functional, execution, and QoS semantics of geospatial services.

Workflow Modeler
The tool can allow users to drag and drop various geospatial services to visually generate workflows and interact with the workflows in a virtual globe environment.

Service Evaluation
GeoQoS offer you a easy way to test and evaluation the quality of geospatial processing service. And you can check QoS information in a visualizaiton way.

Service Chain Optimization
With friendly service chain optimization wizard, GeoQoS hellp you select optimal composite services to help you go through your geospatial process.

QoS Information Visualization
You can see some of the information presented in the 3D environment with WorldWind, you can use web service to accomplish your work visually.
