distributed HR-DDS nodes. Using a HR-DDS interface, users at the HR-DDS virtual server may access all HR-DDS<br />
granules (maintained at distributed locations, served by local DODS servers) using DODS aware client applications as if<br />
they were a single data archive residing on a local computer.<br />
160 AP5-014 In addition to DODS access, HR-DDS granules may also be accessed using secure ftp (sftp) transactions or through a Live<br />
NASR<br />
Access Server (LAS, http://ferret.pmel.noaa.gov/Ferret/LAS/). LAS is a highly configurable Web server designed to<br />
provide flexible access to geo-referenced scientific data and can present distributed data sets as a unified virtual data base<br />
through the use of DODS networking<br />
160 AP5-015 Using a web browser interface LAS enables a user to visualize data with on-the-fly graphics; request custom subsets of<br />
NASR<br />
variables in a choice of file formats ;access background reference material about the data (metadata) ;compare<br />
(difference) variables from distributed locations<br />
161 AP5-016 LAS enables the data provider to unify access to multiple types of data in a single interface ;create thematic data servers<br />
NASR<br />
from distributed data sources ; offer derived products on the fly ; remedy metadata inadequacies (poorly self-describing<br />
data) ; offer unique products (e.g. visualization styles specialized for the data)<br />
161 AP5-017 LAS will be used extensively in the GODAE project and will allow data to be extracted from many operational ocean model<br />
NASR<br />
systems for inclusion and comparison with HR-DDS SST data. In addition, the LAS system is in active development to<br />
provide advanced features such as temporal aggregation of data and advanced display options in collaboration with the<br />
GODAE <strong>Data</strong> Sharing Pilot Project.<br />
