From Wuhan University:
GeoJModelBuilder couples geosprocessing Web services, NASA World Wind, and Sensor Web services to support geoprocessing modeling and environmental monitoring. The main goal of GeoJModelBuilder is to bring an easy-to-use tool to the geoscientific community. 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. It also allows users to audit trails of workflow executions, check the provenance of data products, and support scientific reproducibility.
