In this context and for a project provided by the french forest national office (ONF), in order to deliver a near real tile deforestation monitoring process, we develop a set of tools allowing to monitor deforestation using Sentinel-1 data. The main process of the approach are (i) Calibration and Orthorectification over user study area (shape file), (ii) Temporal Adaptive speckle filtering, (iii) Adjust time series level and smooth it, (iv) Deforestation analysis. Deforestation analysis is based on applying a threshold of the differences between a reference date (usually the oldest date) to the current date. If this change is significant we expect a deforestation process and give the current date as deforested label in the deforestation map.

This open source tool box is mainly based on Orfeo ToolBox for Sentinel-1 pre-processing and is based on specific python script. All the toolbox is integrated in QGIS and available in a QGIS RemoteSensing toolbox for windows or using the following for Ubuntu users https://gitlab.com/clardeux/FOSS4G-fr-2018-Atelier-Radar.

* **[CONFIRMED]** ZOO-Project: the way to use OTB applications as WPS services (Gérald Fenoy - Geolabs)
> The ZOO-Project is an open source software which provides a Web Processing Service (WPS) compliant and developer-friendly framework to easily create and chain Open Geospatial Consortium (OGC) Webservices. It supports both 1.0.0 and 2.0.0 versions of the OGC specification. It can handle execution of WPS Services implemented in various programming languages and can also take advantages of various processing engine such as OrfeoToolBox (OTB). Using this ZOO-Project support gives users the capacity to use OTB applications remotely from any WPS client. The presentation will quickly introduce the specific capabilities of the ZOO-Project such as automatic publication of result using OGC Web Services through MapServer and how this can used when using OTB applications as WPS services. Also the current development status of the High Performance Computing (HPC) support in the ZOO-Project will be presented. With this support, one will be able to not only to execute OTB applications that runs locally to the WPS Server but also invoke OTB applications that will run on HPC server.

> The differential SAR interferometry (DInSAR) technique relies on the processing of two SAR images of the same portion of the Earth's surface taken at different time. The aim is to analyze potential events (earthquake, destruction, ...) by highlighting differences between SAR images. DInSAR involves a set of tools such as creation of deformation grids , coregistration or building of interferograms. An Orfeo Toolbox remote module (DiapOTB) contains all necessary steps and allows to launch a complete DInSAR chain. The DiapOTB module were used with Sentinel-1 data with satisfactory results. > The differential SAR interferometry (DInSAR) technique relies on the processing of two SAR images of the same portion of the Earth's surface taken at different time.
