Data And Information Access Link (DIAL)
DIAL is a web-based distributed system to search, access and visualization satellite remote sensing data for Global Change research. It allows data providers to easily serve their Earth science data directly to their users. DIAL provides traditional catalog services like metadata search, while also providing extended interactive data services like browsing, subsetting, subsampling, reformatting, and direct downloading. The power of DIAL has recently been enhanced by the addition of the EOSDIS “Version 0” protocol, which enables a project to set up a distributed system of DIAL servers.
In collaboration with NASDA and other institutions, NASA has DIAL servers set up to distribute satellite remote sensing data. NASA and NASDA also collaborate on the Tropical Rainfall Measurement Mission (TRMM); 3D data is transferred from NASA to NASDA using TransPAC/APAN, processed and visualized for the web.
