The project “Integrative Landslide Early Warning Systems (ILEWS)” was sponsored by the BMBF from 2007 to 2010. The company terrestris was involved in this project and instrumental in geodata management and developing the portal. The project report has now been published as a book by the publisher Klartext. The book has the international standard book number (ISBN) 9783837503616. The book describes the scientific problem, the methodology, results and a guideline containing 15 vital points for dealing with gravitational mass movements. The book (which is unfortunately only available in german) can not be bought, but you can obtain a copy for a nominal fee. Interested people can just contact terrestris until the final procedure has been sorted out.
