    Abstract: Sensor observation can be applied in the field of emergency management for predicting, monitoring and managing ecological risks locally and regionally. However, due to technical limitations, sensor observation marginally meets the challenges in this area. A standardized access to observation data would allow the reuse of data, as well as transnational and multidisciplinary usage. This paper introduces standards for sensor observation data, specified by the Open Geospatial Consortium. These standards comprise a definition of data models, xml-encodings and service interfaces, in order to make different types of sensor and sensor data accessible and useable via the internet. Additionally, the paper elaborates on the application of these standards in the domain of avalanche prediction and snow risk monitoring. A free open source implementation of the standard by the 52 North Initiative for Geospatial Open Source Software GmbH was chosen. A simple home weather station was deployed on our Departments rooftop to collect observation data for our experiments. We present the use of these standards on specific applications, such as observations made by a human, made by a meteorological weather station or the output of an algorithm for the correction of raw observation data values, and discuss the advantages and limitations experienced.
