Earth Observation Time Series Analysis Toolbox
Co-development of an Earth Observation Time Series Analysis Toolbox for Proba-V data
The focus of this project is the implementation of a time series analysis toolbox for remote sensing imagery in R. The Luxembourg Institute of Science and Technology (LIST) developed the toolbox for the European Space Agency (ESA) according to the needs of the NDVI time series analysis community. 52°North contributed to the toolbox development (outside project funding). The mission exploitation platform (MEP) at VITO (Flemish Institute for Technological Research NV, Belgium) derives the data from their Proba-V satellite.
The toolbox largely builds on existing specialized R packages and functions for raster and time series analysis combining these in a common framework. In order to ease access and usage of the toolbox, it is deployed in the MEP Spark Cluster and wrapped in a Web Processing Service (WPS) using 52°North’s WPS4R extension. The WPS is also re-used in the Automatic Service Builder (developed by Space Applications Services NV/SA, Belgium). Hence, the analytics developed in R can be integrated into a larger workflow potentially integrating external data. The WPS provides a Webclient including a preview of the results in a map window for usage within the MEP.
Our team finalized the EOTSA toolbox in 2020. We also held a one and a half day workshop at LIST illustrating the toolbox usage and implementation details.
