With new data comes new possabilities.
Recent papers have suggested the use of Flickr data for travel cost studies. This greatly reduce the time spend collecting data and might give new insights.
I propose a project that would investigate the use of this data in Denmark. The project would be exploratory but will be the first of it's kind in a nordic country (to the best of my knowledge).
The applicant needs to be comfortable with large scale data manipulation and geografic analysis preferably in QGIS/ArcGIS. A good understanding of econometric methods of discrete data is reccomendable but not a must.
If this is of interest then don't hesitate to contact me and we can dicuss specific topic and extend.
