3. WHY THE GEOHAZARDS
EXPLOITATION PLATFORM ? "

4. Ø A platform to support the exploitation of satellite
earth observations for geohazards
Ø A community portal helping you to access and
exploit geohazards related data and processors
Ø A social place where to share your work
Ø A platform to integrate and run your own
processing service
Geohazards Exploitation Platform Mission

5. The geobrowser is composed of:
Ø The Map, where the user can make search
queries and see results
Ø The Contexts areas, to organize views on results
Ø The Results panel, and the user Basket panel
Ø The Processing services panel
Platform services The geobrowser

6. The Cloud dashboard allows to:
Ø Browse the Virtual Machines created on GEP
Ø Create a new Virtual Machine
Ø Create a new ESA Cloud Toolbox for a Data Analysis
Ø Create a new Developer Cloud Sandbox for the Portal
integration tools
Platform services The cloud dashboard

7. HOW TO BUILD MY FIRST APP
READY MADE FOR GEP"

8. Small GitHub survival guide:
Ø Import an application template from GitHub
Ø Change the GitHub remote reference
Ø Commit your work
Ø Synchronise to repository
Settings Working with a Developer Cloud Sandbox

9. Define your application as a Directed Acyclic Graph
Ø Define inputs type, outputs and transactions
Ø Number of nodes vs Number of inputs
My application The workflow

10. Ø Job templates
Ø Executable scripts types
Ø Workflow instance
Ø Scope of sources and parameters:
exploiting the WPS interface
My application Workflow descriptor

11. Ø Preparing the environment
Ø Reading the inputs
Ø Calling the processor binaries
Ø Staging out the results
My application Run executables

12. DELIVERING MY PROCESSOR TO
USERS ON GEP"

13. Ø Installing the Application
Ø Using the ciop-run command
Ø Testing from the Cloud Sandbox Dashboard
Ø Web Processing Service (WPS) interface
Ø Finally, ready to be used on GEP
Platform integration Testing the workflow

14. User operations:
Ø Fill the form with inputs from a Data Package
Ø Run a job with a public visibility
Ø View/download the job results
Platform integration Sharing processing jobs
