Data system considerations for remote sensing

The availability of data obtained with the aid of Landsat and other remote sensing satellites provides potentially the possibility to study problems on a global scale. Difficulties arise, however, in connection with the diversity of data formats, archival conditions, and the need for data registration. Systems are being planned to test the ability to reduce some of these difficulties. Details regarding the given situation are examined, taking into account global problems which are being considered. These problems are related to the global carbon dioxide cycle, and the biogeochemical cycle. Attention is given to pilot data systems, considerations for spatial data, data format considerations, data quality considerations, aspects of data base design, and system aids.
