Subject: E(26/7091)Access to Information request - 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
