Comprehensive Plan
“… multiyear process in
which planners work closely with
residents and other professionals
to identify and describe
community characteristics,
articulate goals, and explore
alternative plans for the future.”

Economic Development

Many comprehensive plans include
economic development

LDM provides tools for benchmarking

Snapshot of GIS-based local & regional
economic data

An opportunity to study economies at a
regional scale

Value added:

Research on various sources of public economic
data

Research on useful indicators

Feedback from pilot counties: Porter, Jasper, etc.

Reliant on ArcIMS axl file
A
broken connection from axl to
database(s) causes a failure in Geocortex
– no site!
 Miss-coding
in axl file also results in loss
of map service.
Wrap-up





Map service built into LDM is
extremely powerful.
All you need is a computer and
an internet connection.
Our integration of Phase 1
(Inventory/Analysis) and the
map service is well underway.
Other parts of the decision
system planned over the next 2
to 3 years.
We need feedback!!!
