Data management and SDI – Experiences from the GITEWS project

Abstract

Abstract – For the BMBF project GITEWS, the German contribution to a tsunami early warning system for the Indian Ocean, a geodata repository was established. This repository contains all geodata, which were required for the development and implementation of GITEWS. During the stage of requirements analysis all available and relevant data were acquired and collected. This process was realized in close collaboration with the Indonesian partner organizations. During the harmonization process several quality control procedures were performed to ensure the maximum possible quality and reliability. On the on hand the geospatial data were provided to the different work groups in the project. On the other hand the data repository was integrated in the Early Warning and Mitigation System, providing a large geodatabase for the Decision Support System. The data access to the repository was realized by using OGC compliant web services (WMS, WFS, WCS, CSW 2.0).
