Greetings Sensor Web Community,

My name is Christian Danowski and I plan to finish my Bachelor degree in geoinformatics at the University of Applied Sciences Bochum in February next year. Prior to the Bachelor thesis, I had the great opportunity to experience a twelve week internship at 52°North (52N). I intend to share my experience with you in this blog article.

During the internship, my task was to develop a new data source component for the 52N Sensor Observation Service (SOS) within the context of the European Project GEOWOW. The idea was to use a file system of NetCDF files as a data source instead of a database. Hence the necessary information provided to the SOS is not stored inside a database like PostGIS anymore, but in the NetCDF files itself. In the following paragraphs I will try to briefly explain the background of NetCDF and the steps of the development process.

OpenSensorSearch – Final blog post

The aim of the OpenSensorSearch project is to provide an implementation of a sensor discovery server with the high performance of a Solr back-end to give users results fast. In addition, we are working on harvesting mechanisms for OpenSensorSearch (OSS) to allow users and developers to write harvesters for their own sensor data sources.

In the previous blog post, we discussed the work done in the first few weeks related to the database back-end and how we used Apache Solr for indexing and fast searching. Today we present the work done in the second half of the project. It focussed on harvesting metadata from other sources and the user interface. I mainly discuss

Javascript harvesting mechanism,
“harvest callback” technique,
user interface implementation with Spring MVC and
general technical details.
