▶Hands-on focus

An application lifecycle

▪ Processing libs developed in any programming language supported by CentOS 6.5

▪ C/C++, Java, Python (most common)▪ Matlab and IDL▪ Other languages shall be

previously analyzed

▪ Then synchronized onthe Platform via softwarepackages management tools(RPM repos, GitHub, …)

Design & Libraries Declaration (1/4)

Python, CDAT, R, BEAM, BEAT

Service integration (2/4)

▪ Service developer uses the sandbox tools to implement, test and validate a scalable workflow

▪ Sandbox includes tools to proof test data discovery, parallel processing and access to results

9Cloud Compute deployment (3/4)

▪ After validation, the developer publishes the Service for integration on a selected Cloud Infrastructure

▪ A ‘Processor as a Service’ accesses complete pools of datasets,allows application intensive computing, and stores processor outputs, e.g. back to the lab

10Service Operations (4/4)

▪ Processing Services are operated on a selected Cloud provider

▪ Operators manage the service via their user account on Terradue Cloud Platform

▪ Resources can scale up/down▪ The development environment

remains active for maintenance activities on the Service

▪ Service End Users can access the service’s products from ad-hoc community portals

▪ Includes support for standard protocols like OGC Web Services

Hands-on sessions

12Hands-on sessions overview

Session 1 - Data access and adding your own data to the platform Cloud storage

What are the Platform APIs, along with integrated tools for data staging within Cloud Apps, that deliver custom data management services to registered developer users on the Platform ?

Session 2 - Develop your own processing chain, using existing modules

How registered users are able to create a work environment with state of the art tools like Git and GitHub, Maven, Oozie workflows, … and work collaboratively for the development of powerful Apps ?

Sen2Cor is a processor for Sentinel-2 Level 2A product generation and formatting; it performs the atmospheric, terrain and cirrus correction of Top-Of- Atmosphere Level 1C input data.

Sen2Cor creates Bottom-Of-Atmosphere, optionally terrain and cirrus corrected reflectance images; additional, Aerosol Optical Thickness, Water Vapor, Scene Classification Maps and Quality Indicators for cloud and snow probabilities.
