FROM DISCOVERY TO DOWNLOAD - THE EOWEB ® GEOPORTAL (EGP)

The EOWEB® GeoPortal (EGP) is the new DLR multi-mission web portal for interactive access to long-term archived Earth Observation (EO) data. EGP implements two innovative approaches. First, it seamlessly integrates the classic catalogue-and-order functions of the current EOWEB®-NG portal with new browse-and-download features. Thus, the whole process from “Discovery” to “Download” is combined in one single tool. Furthermore, EGP offers an interactive, responsive, user friendly and appealing state-of-the-art user interface similar to a desktop application. Secondly, it uses common interoperability standards of the Open Geospatial Consortium (OGC) and ESA’s Heterogeneous Mission Accessibility (HMA) initiative. These standards enable EGP to communicate and integrate with the heterogeneous data sources of the German Satellite Data Archive (D-SDA), as well as external data sources. Finally, the core functionality of EGP is separated into detached components, which are further subdivided into three different tiers. This entails that new functionality can be easily added and EGP is customizable for the use of new satellite missions or projects.
