A web based geoenvironmental data exchange information system

Different geoenvironmental databases exist in European countries. They are dispersed and have various standards and languages applied. Thus their usefulness and availability are limited, although geophysical information may be very effectively applied, processed and interpreted for a wide variety of purposes. Processing will be enhanced if these databases are integrated in a certain level and accessed via the Internet, offering cross border, European-wide, unified electronic services, making geoenvironmental data much more available. In an effort to increase utilization of geoenvironmental data the MILDMAP-MEDIA consortium has developed an web based data exchange system that provides a convenient storage point for documenting, archiving and exchanging datasets. The users of the system can enter metadata that describe their datasets, upload their dataset files, edit their entries, search for data using specific criteria, browse metadata of datasets in the system and download datasets from the system. The functional design and implementation of this system are presented.
