| Geographic
Information System (GIS) for tree inventory control
In Hong Kong, there are
around 82,000 trees were planted and lots of enquiries form
both the public and district councilors on tree information
received. Therefore, a centralized Geographical Information
System (GIS) to cater for such volume of tree data including
e-maps, digital photos and spatial information was developed
for the Hong Kong Government and now internet access for
the public and the departments are provided. Generally,
the multi-user GIS allows access by 300 internal staffs
who engages in tree maintenance services and the embedded
system can also be implemented on PDAs for users to carry
out their daily tree survey tasks. The challenge of this
project is the provision of High Availability solution to
support the necessary data replication procedures and the
growing capacity by adding new servers.
