This contribution deals with an initiative to develop a national landslide database for the Federal Republic of Germany. The paper highlights the structure and contents of this database and outlines its system architecture that underlies the current database transformation. With this background, the paper examines the database potential for research on landslide disaster impacts and hazard mitigation.
Due to systematic and continuous regional data compilation, the landslide database offers a differentiated data pool of more than 5,000 data sets and over 13,000 single data files. It dates back to 1137 AD and covers landslide sites throughout Germany. Besides closing an important data gap at the European level, the database has a key function in the country, as it integrates several existing landslide archives.
In seven major data blocks, the database stores information on landslide types, dimensions, and processes as well as the connection of landslides to soil and rock properties, geomorphometry, and climatic conditions. The database also includes data on land-use effects and damage impacts, disaster mitigation, and landslide costs. A useful feature is its capacity to support development of statistical data products, including time series, index and threshold values, data tables, and diagrams.
The upcoming migration to PostgreSQL/PostGIS improves data storage and geospatial data exploration. Furthermore, it enables the implementation of a WebGIS information platform for knowledge transfer.
