The ORNL DAAC now offers a Web map server to help users choose sites that have subsets of MODIS satellite imagery.
Users can choose from over 270 sites worldwide and retrieve files for selected MODIS Land Products in ASCII format. The subsets measure 7- by 7-km and are centered on a flux tower or field site.
To access the map server, visit the MODIS ASCII Subsets page and click on the "MODIS Map Server" link in the bar at the top.
The map server requires a java plugin that can be installed from a link at the bottom of the map server Web page.
