AB: The Laboratory for the Ocean Observatory Knowledge INtegration Grid (LOOKING) is a NSF research project focused on the identification, synthesis and assembly of existing and emerging concepts and technologies into a coherent viable cyberinfrastructure design for ocean observatories. One of the goals of the project is to prototype an automated pipeline for continuously generating visualization products (time variant geometric representations and rendered image sequences) from streaming and regenerating data sources. Current work involves remote visualization of NASA JPL's Our Ocean Data Assimilation of the Central California region on a continuous basis. The prototype uses OPeNDAP as the data retrieval mechanism to fetch netcdf formatted data for specific variables or time steps. A geometry conversion engine transforms this data into 3D geometric models (e.g. isosurfaces for scalar data like temperature and salinity or streamlines for ocean currents) using the Visualization Toolkit (VTK) and delivers a 3D scene graph that can be imported into the end user's choice of visualization software for viewing the scene. Our current preferred 3D viewer is ossimPlanet (a 3D Geospatial viewer built using OpenSceneGraph, libwms and OSSIM) embedded inside the COVISE framework for interactive exploration in a georeferenced framework.
