Praevention durch Fernerkundung. T. 1 und 2: Erprobung von Methoden der Fernerkundung zur Erkennung von Destabilisierungsprozessen an der Erdoberflaeche Endbericht

Multisensor satellite and airborne remote sensing has been used to detect subsidence and collapse-prone areas caused by underground mining and to test and improve remote sensing methodology for hazard detection. The study area is characterized by abandoned lignite and potash mines. The fact that the abandoned mines were only partly stabilized is the reason for the development of subsidence and collapse sinkholes, which are still forming today. In this study, satellite and airborne data proved to be the most effective remote-sensing approach in investigating hazards caused by abandoned underground mines. It was demonstrated that combinations of high-resolution air photography, laser scanning and satellite imagery can be used to detect specific ground features associated with fracturing, subsidence and weakened rocks. Combining different sensors helped to produce more reliable and less ambiguous results. Satellite and airborne remote sensing systems used each provided independent evidence of subsidence and collapse hazards as follows: Landsat TM, SPOT and IRS-1C satellite data to detect moisture-related anomalies associated with local subsidence-related fracturing, stereoscopic aerial photography to detect fracture features, airborne laser scanning to locate local depressions a few centimeters or tens of centimeters deep (high resolution elevation modeling). Evidence for the effectiveness of this remote sensing methodology was provided in April 1998, when a collapse sinkhole (about 30 m in diameter and about 10 m deep), occurred at a site, which had been evaluated by interpretation of air photographs, laser data and satellite imagery as being highly collapse prone. The investigations have demonstrated that airborne laser scanning may represent a powerful new tool within multisensor remote sensing for early recognition of ground instability. Further, it could be demonstrated that geo-environmental research based on high resolution MOMS satellite data can contribute to investigating complex geo-environmental problems related to salt at the Khorat Basin in Thailand.

Leadership dynamics promoting systemic reform for inclusive service delivery

This article presents a multicase study of two systems of schools striving to reform service delivery systems for students with special needs. Considering these systems as institutional actors, the study examines what promotes the understanding and implementation of special education service delivery within a system of schools in a manner that strengthens the capacity of schools to welcome students with special needs. Key findings illustrate how central office support and relationships across horizontal, vertical, and diagonal dimensions mediate efforts to reorient organizations, establish policy coherence, provide instructional leadership, and maintain the focus on reform. The article concludes with implications across school sectors for policies and practices that promote inclusive service delivery for students with special needs
