AB: With the advent of a growing number of NASA mission data centers there has been increasing interest and efforts towards the creation of "Virtual Datacenters" or "Virtual Observatories". These Virtual Observatories would tie together large data holdings allowing particular regions of space and the near Earth environment to be studied more completely. With the increasing reliance on remote sensing instruments (all of the instruments on the NASA TIMED satellite are remote sensing for example) in the SEC community a flaw in the current designs for Virtual Observatories in the ITM community can be seen - the metadata required for satisfactory high-level querying of data involving multi-satellite configurations does not exist. This is because adequate information on the location of instrument field-of-views and satellite locations are not provided in the metadata. In addition, one satellite instrument may generate metadata in one coordinate system (e.g. magnetic) and another in another coordinate system (e.g. geographic). Currently, the metadata available for existing instruments and satellites does not allow for queries to be made determining when instrument fields-of-view overlap or requiring conversion between different coordinate systems or allowances for propagation delays. In this talk we will describe a virtual metadata generator that allows intersections between different satellite instrument observation regions to be determined as well as conversion between coordinate systems all in real time as part of a data discovery query. This virtual metadata tool would be implemented as part of a broader structure of web services that can be plugged into existing and future virtual observatory designs allowing them to better serve the science community.
