The OPeNDAP Data Connector

The OPeNDAP Data Connector (ODC) is a program which allows you to search for and retrieve datasets published by OPeNDAP data servers. OPeNDAP servers (also known as DODS servers) located at major institutions around the world serve a wide variety of data including: climatic data, satellite imagery, and ocean sensor results. The ODC allows you to find these datasets, download them to your machine, save them, and import them into client applications like IDL, Matlab, SPSS, Excel, or into databases such as Access and Oracle, and plot them with advanced graphics capabilities. The ODC is your gateway to terabytes of scientific data and imagery.
