A final wrap up of the Google Summer of Code project: Trajectory Analysis in R can be found in RPubs here.
This is the last blog post I will be making for the Seismic SOS project!. If anyone has been keeping up with or has read my weekly reports page you will see that it has been a huge learning process for me, and I just want to say that I am very grateful to have been given this opportunity by 52°North, GSOC 2013, and the open source community.

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
- “harvest callback” technique,
- user interface implementation with Spring MVC and
- general technical details.
On the 17th of June, work started on creating a new web admin application for the 52° North WPS. The project aimed to achieve the following three goals. The first was to make managing, maintaining, and extending the code easier for project developers. This was achieved by having a layered architecture to deal with separate concerns and responsibilities. The second goal was to provide a way for third party developers to integrate their modules to the application with minimum effort. A configuration API was developed to achieve this. The final goal was to improve the usability of the system by creating a new, modern, and flexible user interface.
I have discussed the goals and initial plan in the first blog: New 52° North WPS Admin Web Application, and reported on the progress half way through in the second blog: 52° North WPS Configuration Management Reloaded. In this final blog, I’ll focus on the end result and what has been achieved.
Next week the FOSS4G 2013 Conference will take place in Nottingham. This is a great opportunity to meet geospatial open source enthusiasts from all over the world.
For the sensor web community it is especially a chance to chat about the current 52°North Sensor Web developments, your experiences with our implementations, and future development plans. We are looking forward to meeting you at the conference. If you are interested to meet at FOSS4G please let us know via email: firstname.lastname@example.org.
On Friday (September 20th) there will be a 52°North Sensor Web presentation: “An API For Visualizing Data From The Sensor Web” (http://2013.foss4g.org/conf/
placed on top of SOS servers or sensor data based and will make it very easy to develop your own client applications for sensor data.
Finally, we are trying to organize a Sensor Web Birds of a Feather session on Friday (http://wiki.osgeo.org/wiki/
