Custom backend of the 52°North SOS for the AWI NearRealTime database with support for the following operations:

  • GetCapabilities
  • DescribeSensor
  • GetFeatureOfInterest
  • GetObservation
  • GetDataAvailability

Configuration

The connection to the NRT database can be configured in src/main/webapp/WEB-INF/hibernate.properties or <webapp>/WEB-INF/hibernate.properties. A template can be found at src/main/webapp/WEB-INF/hibernate.properties.template

SOS metadata (like Service Provider and Service Identification or the external URL of the service can be configured in src/main/webapp/configuration.json and <webapp>/configuration.json respectively

Logging is done using Logback and can be configured in src/main/resources/logback.xml and <webapp>/classes/logback.xml respectively.

Building

The service requires Java 8 and Maven:

mvn clean install

The WAR file can be found at target/de.awi.sos.ui.war

Deployment

The WAR file can be deployed in a Java Application Server of your choice. Please adjust the configuration files (especially hibernate.properties either prior to building or in the WAR file.

Docker

There is a Dockerfile that creates a Jetty deployment:

docker build -t awi/nearrealtime-sos:latest .
docker run -it -p 8080:8080 \
  -v ./logback.xml:/var/lib/jetty/webapps/ROOT/WEB-INF/classes/logback.xml:ro
  -v ./hibernate.properties:/var/lib/jetty/webapps/ROOT/WEB-INF/hibernate.properties:ro
  -v ./configuration.json:/var/lib/jetty/webapps/ROOT/configuration.json:ro
  awi/nearrealtime-sos:latest

Be aware that you have to link the database to the container or have both containers on the same Docker network.

After this the SOS should be accessible at http://localhost:8080/service?service=SOS&request=GetCapabilities

A docker-compose example deployment can be found here.

Development

An extract of the AWI NearRealTime database can be found here as a Docker image.
