摘要

The primary objective of the cooperative research and development is to produce an integrated, quality controlled, global database (including time sequences) for spatially distributed modeling. The project concentrates on modern observational data, including remotely sensed data and data from other sources. The database includes complementary multi-thematic data sets on compatible grids, registered to a common origin and projection (latitude-longitude). The database has been structured to be operable with several existing Geographic Information Systems (GIS), so that a complete analytical package could be provided to reviewers and other scientists for evaluation, experimentation, and further development. The software accompanying the CD-ROM (a subset of the GIS known as Idrisi) was developed and adapted for the project at Clark University. Although compatible with Idrisi, the database is also designed to be easily up-loaded to the GIS known as GRASS, running on UNIX operating systems. Since the database structure is as system independent as possible, it should also be easily usable in other systems.
