3.4 Retrieving and Processing
In both types of research, the GPS device is handed to participants.
Data retrieval will take place after returning the device.
In the next step all data is cleaned and validated. A tripdatabase
including all trip-related information will be build. The database
will be connected to the spatio-temporal data using the TRIPID
field.
3.5 Analysis, Visualisation and conclusions
After the spatio-temporal data is joined with the background information,
queries and calculations can be performed to analyze
the data. A clear research question is essential to select the appropriate
attributes and context information. The context can be
defined based on the theoretical framework of the research
question. The data can be analyzed on an individual level (per
track) or on a generic level (per set based on a query). Conclusions
can be drawn by comparing different attributes, by equating
different themes or by confronting parts of the dataset with
exogenous data sources.
