DESCRIPTION:The Copernicus Ground Motion Service (EGMS) is a European Union
  (EU) initiative under the Copernicus program\, which aims to provide near
 -real-time information about ground deformation caused by natural or man-m
 ade hazards. The service uses a variety of data sources\, including satell
 ite radar imagery\, to monitor and analyze ground motion in areas prone to
  landslides\, sinkholes\, earthquakes\, and other hazards. Given the sensi
 tive nature of the service\, EGMS product validation is a key activity in 
 assuring the user community (especially the decision makers) of the qualit
 y of the ground motion and deformation information provided.\n\n\nThe main
  goals of the EGMS validation system are as follows: to provide a reproduc
 ible environment on top of modern cloud infrastructures (with a particular
  focus on the European geo clouds)\, to enable the development of scientif
 ic tools that validate EGMS characteristics\, to facilitate the reproducib
 ility of the validation tasks\, and to account for key performance indicat
 ors (which will allow shareholders to monitor the quality of the primary E
 GMS product).\n\nTo achieve the first goal of providing a reproducible env
 ironment\, we have focused on providing Terraform modules that facilitate 
 the deployment of our software stack on any supported cloud platform. The 
 software stack is built on top of the Kubernetes container orchestration s
 ystem\, which runs on top of a managed cloud environment. Kubernetes provi
 des uniform services regardless of the underlying cloud platform.\n\nFor t
 he goals of developing the validation tools and the execution of those too
 ls we decided on using an unified approach based on the JupyterHub solutio
 n. JupyterHub is used for providing an unified development environment bas
 ed on R and Python EO software tools (based on modified Pangeo Docker imag
 es). Also Jupyter is used for executing the validation tools outside of Ju
 pyterHub by leveraging an internal python service that uses papermill to e
 xecute the notebook and then “nbconvert” to generate a html webpage co
 ntaining the required visualizations and documentation in human readable f
 orm.\n\nThe validation system is complemented by an bespoke web dashboard 
 aimed for providing reports and information related to the status of the v
 arious key performance indicators.\n\nOverall the whole validation system 
 was developed by solely using FOSS4G components: GeoPandas\, RasterIO\, Ge
 oNode\, GeoServer and JupyterHub.
