52°North successfully completed its second participation in the Google Summer of Code. We are happy to announce that all four students did a really great job in their projects. Thanks to all participants – students and mentors alike! If you have been following the blogs over the course the summer/fall, you will have read about the particular projects previously.more >
Trajectory Analysis in R – Final Post
A final wrap up of the Google Summer of Code project: Trajectory Analysis in R can be found in RPubs here.
Meet The New 52° North WPS Admin Web Application
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.
Trajectory Analysis in R – Midterm Post
This project aims to develop methods and classes specifically designed for trajectory analysis. Over the past five weeks, I have made progress in three main aspects.
First, I have been learning the basics of developing packages for R and making a transition from an R user (a.k.a. a useR) to an R developer. Second, I wrote a function for converting raw trajectory files into STI objects and eventually into STTDF objects. Third, I wrote an additional function to enable a simple spatial overlay operation between one or more STTDF object(s) and a SpatialPolygons object (from sp package), both at the individual point level, as well as at the trajectory level.more >
