AIS stands for Automatic Identification System. It is the location tracking system for sea vessels. This module illustrates how to load big AIS data sets into MobilityDB and do basic exploration.
The idea of this module is inspired from the tutorial of MovingPandas on ship data analysis by Anita Graser.
This module covers the following topics:
Loading large trajectory datasets into MobilityDB
Create proper indexes to speed up trajectory construction
Select trajectories by a spatial window
Join trajectories tables by proximity
Select certain parts inside individual trajectories
Manage the temporal speed and azimuth features of ships
