Global Land 1-KM AVHRR Project
Data Distribution
The main objectives of phase I are the acquisition, archiving, and distribution of a global land 1-km AVHRR data set. To facilitate the data distribution, a complete copy of the data set will be held by NOAA, ESA and the EDC. The EDC provides ESA a copy of all the data provided by NOAA and the EDC HRPT station and will provide NOAA with a copy of all data received by ESA and the EDC HRPT station.
Each agency is committed to facilitate access to the data by traditional methods and networking. Information Management Systems (IMS) have or are being established to provide access to the data. The IMS at the EDC for these metadata records and digital quicklooks is called the Global Land Information System (GLIS) (Oleson et al., 1991) that allows users easy and flexible access to the AVHRR data base. Users can conduct queries, graphically view the coordinate metadata, observe the digital quicklooks and order data. Information about the IMS's can be obtained from the respective agencies.
