The alpine infrastructure of trails and huts enables access to the Alps and is an essential element of summer tourism. Mass movements, whose frequency and magnitude are expected to increase due to extreme rainfall events associated with climate change, frequently affect this infrastructure. Alpine associations need to adopt new ways within their ma...

The hiking infrastructure of trails and huts is a strong asset for summer tourism in the AustrianAlps. However, this infrastructure is prone to different types of mass movements, such as rainfall-induced shallow landslides, debris flows and rockfalls, that potentially block the access tomountain huts and hiking routes for weeks or even months. Thus...

Before an object-based image classification can be used, one has to evaluate if it qualifies for its designated purpose, because uncertainty occurs in the complex process of object-based image analysis (OBIA). The range of potential OBIA applications produces objects of a variety of conceptualisations that require a flexible validation concept base...

This paper comprises a discussion of methods for line error measurement. It focuses on three known methods and suggests a forth one based on the evaluation of equally distributed sample points (EDSP) on line features. It is argued that this method of error measurement does not only provide the extent of error but also indicates systematic displacem...

In MontEO (http://monteo.zgis.at/), we investigate the opportunities for EO-based mass movement mapping and hazard impact assessment for alpine infrastructure. We discuss the ways of usage in management and maintenance of trails together with trail keepers of the Alpine clubs. This allows us to refine the concept behind MontEO. We develop a multi-scale approach and combine optical and SAR satellite data (e.g. Sentinel-1/2, Pléiades) to comprehensively map mass movements and to identify (potentially) affected trails and huts for an assessment of the impact on alpine infrastructure. This process is complemented with fieldwork.

Die Mehrheit der Weltbevölkerung lebt in urbanen Räumen. In diesen leisten städtische Grün- und Freiraumflächen einen wichtigen Beitrag zum Wohlbefinden der Stadtbewohner*innen. Das stetige Städtewachstum führt zu einer intensiveren Nutzung der Grünräume. Deren Gestaltung sollte besser auf die vielfältigen Bedürfnisse der Bürger*innen abgestimmt werden. Im Forschungsprojekt grünOase werden neue Ansätze für eine smarte Gestaltung und Bewertung solch grüner Stadtoasen erarbeitet. Der Diskurs mit den Nutzer*innen dieser Räume ist für eine nachhaltigen Stadtplanung wesentlich. Urban green spaces and recreational areas are essential contributors to the quality of urban life by supporting human well-being, and often are threatened by urban growth. Therefore, sustainable planning has to adapt the variety of needs of citizens to the services provided by urban green. The project grünOase aims to develop a concept – including a practical guideline for planners – that integrates quantitative and qualitative information on urban green structures. It supports the communication- and information-based smart design of green and open spaces with an integrative analysis and assessment of green city oases. The grünOase project team employs remote sensing image classifications and enhances them with qualitative information from surveys among users of green and open spaces. The concept is developed for two parks and their respective city quarters in Salzburg in order to test its usefulness in planning and design projects. The concept and the methods will be adaptable to green city oases in other cities.
