Under the Third Runway Expansion Project (3RS), High Speed Ferry (HSF) was re-route due to the construction works. After re-routing, HSF will pass through ecologically sensitive area. One of the mitigation measures is to slow down the HSF within a particular zone.
The project developed codes to filter vessel data collected by AIS, and plot data for investigation.
-
First, you need to have HSF raw data download from internal platform
-
Download the zip files to your local directory
-
Run investigation.py. It will generate two plots, namely spatial plot showing what ships are within the zone in that period. And temperal plot showing the lat/lng against time.
The file defined the boundaries of speed control zone and uses to filter vessels within the zone.
The file uses to generate spatial and temperol plots
