The GIS
system is able to be
shared among
city/county
departments that
want to access and
create GIS
information and
applications. This
system also provides
security and access
to authorized users
of the data as
determined by the
individual
department(s)
responsible for
their data layer(s).
The system also
contains the ability
to view and query
updated information
in a timely and
efficient manner
without adversely
affecting
departments not in
need of GIS
information.
The GIS
Department has
implemented a
centralized database
architecture which
allows GIS desktop
applications to be
supported on user
workstations located
on the central Local
Area Network (LAN),
each with access to
central GIS data
sources. Data
sources can include
GIS file servers,
ArcSDE database
servers, Raster
Image servers,
ArcIMS Intranet and
Internet servers,
and related
attribute data
sources. One central
repository serving
GIS data allows the
GIS department to
implement the
necessary security
procedures and
allows the
simplification of
the necessary backup
requirements of such
vast systems.
Currently
the GIS department
manages over 550GB
of data. Daily
and monthly backups
are done with
additional backups
being stored offsite
for disaster
recovery
purposes.
