The Institute for Geoinformatics has just sent out the new call for applications for the Graduate School for Geoinformatics for summer semester 2014. The call is for
A final wrap up of the Google Summer of Code project: Trajectory Analysis in R can be found in RPubs here.
This week, we will have one blog post by each of this year’s Google Summer of Code students presenting their project and themselves. Jinlong follows Kahlid and Patrick.
Trajectory analysis has a wide range of applications in various fields such as geoscience and social science. Use cases span across mobile phone users (see image below) e.g. for commuting analysis, ship and flight paths or animal tracking. With the avalanche of GPS-annotated data in the past few years capturing such data became much easier, so today there is a need for tools that are specifically tailored for analyzing large-scale trajectory data (example).
R, as a software environment for statistical computing and graphics, has been favored by researchers from various disciplines for its free access, rich statistical methods, and easy-to-share features. However, the classes and methods specifically developed for trajectory analysis are limited and domain-orientated in R. This project intends to address this issue by implementing and improving generic classes and methods for trajectory analysis.more >
