The proposed NASA Deformation, Ecosystem Structure and Dynamics of Ice (DESDynI) mission would be a first-of-breed endeavor that would fundamentally change the paradigm by which Earth Science data systems at NASA are built. DESDynI is evaluating a distributed architecture where expert science nodes around the country all engage in some form of mission(More)
The Augustine Volcano is a conical-shaped, active stratovolcano located on an island of the same name in Cook Inlet, about 290 km southwest of Anchorage, Alaska. Augustine has experienced seven significant explosive To measure the ground surface deformation of the Augustine Volcano before the 2006 eruption, we applied satellite radar interferometry using(More)
(ICESat) laser altimetry profiles. We employ differential interfer-ograms from the ERS tandem mission SAR scenes acquired in the austral fall of 1996, and four selected ICESat laser altimetry profiles acquired in the austral fall of 2004, as ground control points (GCPs) to construct an improved geocentric 60-m resolution DEM over the grounded ice region. We(More)
The following is an industry experience on using well established concepts, domain-specific language and code generation, to automate the engineering process of sub-system interactions. A domain-specific language was used to improve the communication efficiency among several teams of engineers. A code generator transforms the models formed for communicating(More)
