Easy to use time-series data access and analysis tools using standardbased geoprocessing services

Earth Observation time-series data are valuable information to monitor the change of the environment. But access to data and the execution of analysis tools are often time-consuming tasks and data processing knowledge is required. In order to allow user-friendly applications to be built, tools are needed to simplify the access to data archives and the analysis of such time-series data. In this work, web services for accessing and analyzing MODIS and Landsat time-series data have been developed based on the Web Processing Service specification of the Open Geospatial Consortium and made available within the Earth Observation Monitor framework. Algorithms developed to analyze vegetation changes are provided as web-based processing services in connection to the prior developed access services as well. Using the services developed, users only need to provide the geometry and the name of the dataset the user is interested in; any processing is done by the web service.
