Earth Observation Monitor

The Earth Observation Monitor (EOM) is a product based on the Siberian Earth System Science Cluster ( established at the Department of Earth Observation at the Friedrich-Schiller University Jena (Germany). Its development is part of a current dissertation about operational provision of web services for an automatical monitoring of spatial time-series data.

Time-series data from NASA MODIS sensor is provided for easy access and analysis. MODIS Vegetation data are provided by Google Earth Engine for point- and polygon-based analyses. MODIS Land Surface Temperature data is available for selected regions (see layer availability at the bottom of the map).

For analyses the decomposition plot is generated from decompose function of R. BFAST (Breaks For Additive Season and Trend, is used for breakpoint detection, greenbrown ( for trend analyses, and TIMESAT ( for phenological metrics.

The Siberian Earth System Science Cluster and the Ph.D. work are being funded by the Friedrich-Schiller University Jena (Germany) and supported by Jonas Eberle — Web- & Software-Development, Jena.
