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.

Contributions

prosEO is currently developed by the German Aerospace Center (DLR) together with Dr. Bassler & Co. Managementberatung (BCM) and Prophos Informatik. For contributions to the project please contact tangobravo62. For support requests, please contact prosEO-support@drbassler.de.
