prosEO – the Processing System for Earth Observation Data

Introduction

The “prosEO” software system is an open-source processing control system is designed to perform all activities required to process Earth Observation satellite data (e. g. Sentinel data), generating user-level data, engineering data and/or housekeeping telemetry data as desired by a configured mission. The technical infrastructure used to deliver the Production Service is a cloud-native multi-mission infrastructure by design, with strict separation of competences and concerns.

A full description of the design approach can be found on the prosEO Wiki.

Build from source code

To build prosEO from source code, the following prerequisites must be met:

• OpenJDK 11 installed locally

• Maven installed locally

• Docker installed locally (for Windows or Mac: Docker Desktop)

• Run a local registry on port 5000:

  docker run -d -p 5000:5000 --restart always \
       -e STORAGE_DELETE_ENABLED=true \
       -v <path/to/local/registry/dir>:/var/lib/registry \
       --name registry \
       registry:2
  

  The -e and -v options are recommended for better maintenance of the local registry. For the management of the registry we recommend using a GUI tool, e. g. Joxit (https://joxit.dev/docker-registry-ui/). Sample (!) files for running the docker registry and the Joxit GUI are included in the src/docker directory.

• Add the following to your Maven settings file (usually at $HOME/.m2/settings.xml):

  <settings>
    <profiles>
      <profile>
        <id>dev-local</id><!-- or any other id you prefer -->
        <activation>
          <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
          <docker.registry>localhost:5000</docker.registry>
        </properties>
      </profile>
    </profiles>
  </settings>
  

  If you already have a properties element in your settings file, it is of course sufficient to just add the docker.registry property there.

• Add the following to your Docker Engine configuration (e. g. via the Docker Dashboard or manually in daemon.json):

  {
    ...
    "insecure-registries": [
      "localhost:5000"
    ],
    ...
  }
  

• Push the OpenJDK 11 image to your local repository:

  docker pull openjdk:11
  docker tag openjdk:11 localhost:5000/openjdk:11
  docker push localhost:5000/openjdk:11
  

• Install Node.js including npm (installation packages can be found on (https://nodejs.org)).

• Install the raml2html helper ((https://github.com/raml2html/raml2html)):

  npm i -g raml2html
  

To test your development environment, change into the prosEO project directory (the directory, where this README file resides) and run

mvn clean install -Dmaven.test.skip=true

A project setup for Eclipse is beyond the scope of this documentation.

Installation

prosEO is a very complex system, therefore no single installer can be provided. A deployment guide on the Wiki will be added in due course.

Documentation

All documentation can be found on the prosEO Wiki.
