We primarily support three types of data persistence:
- From CSV files.
- From GeoDataFrames
- From PostGIS databases.
Our primary focus lies on supporting PostGIS databases for persistence, but of course you can use the standard Pandas/Python tools to persist your data to any database with a minimal bit of tweaking. And of course you can also keep all data in memory while you do an analysis, e.g., in a Jupyter notebook.
All the read/write functions are made available in the top-level trackintel module, i.e., you can use them as trackintel.read_positionfixes_csv('data.csv'), etc. Note that these functions are wrappers around the (Geo)Pandas CSV, renaming and SQL functions. As such, all *args and **kwargs are forwarded to them.

We support easy parsing of the Geolife dataset including available mode labels.
