Request for Digital Boundary Data (GIS Format) of the 10 Water Control Zones in Hong Kong
Dear Environmental Protection Department,
I am conducting ecological research on Hong Kong coastal waters and require the official GIS polygon boundaries for the ten Water Control Zones designated under the Water Pollution Control Ordinance.
Could you please provide the shapefile or geodatabase file, or advise where it can be downloaded from?
Thank you for your assistance.
Yours faithfully,
Alison
