Fig. 9: alpEWAS live viewer with sensor overview and live webcam

practical tool in the system maintenance is the alpEWAS live viewer (fig. 9). This surface always informs the user on the system status. Furthermore the stream of data can be graphically processed (various filter options and combinations) reviewed. An important intersection in access to data is the access of the end-user, who is interested in information on the current state. The data management concept envisages the following: A real time reflection of the data bank from the data analysis unit (master) on a second data bank server (slave), with a broad band internet connection, allows for high data security and a practically unlimited parallel data access of several users. These complex and computationally intensive analyses can be shifted. For data exchange between heterogeneous systems (interoperability), there is a possibility to access the results through standardized intersections, in case the user has access rights. Up-to-date standards, as required in the sensor web enablement (SWE) initiative of the Open Geospatial Consortium (OGC) for access to space-related data, are taken into consideration.

The main functions of the live viewers (fig.9) is to offer permanent information on the up-to-date system state, as well as the possibility of visualizing graphically processed initial results. The data bank accessed by the viewer (master or slave) can be freely chosen.

Integrative data analysis Data gathered by the sensors installed in the test area are available since February 2009 and first analyses of the obtained time series are possible. The basis of subsequent tests are conclusions from earlier slidings at the Aggenalm, to the effect that a main influencing factor of movement is the influence of strong precipitation in the area. The available data verify the correlation between precipitations, pore water pressure and resulting deformation. One limiting factor is the currently low movement rates in the Aggenalm. Up to now deformations of approximately
