Comprehensive Plan

Definition: “… 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.” (The Practice of Local Government, C.J. Hoch and L.C. Dalton (eds.), 2000, pg. 24)

Planning Process

Objectives

Improve the development and implementation of comprehensive planning.

Incorporate GIS into this planning process.

Use the university’s research and outreach to assist a user in making a decision.

Implement a 3-5 click framework.

farmland, forestland, grassland, and wetland to urban use

• 1992 NLCD Data & 2003 NASS Data used to generate results

• NOTE: Appropriate for applications at the regional scale

• Working Lands• Used in a productive way• Contribute harvestable resources

• farmland• forests• grazing lands

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

Economic Development

Value added: Research on various sources of public

economic data

Research on useful indicators

Feedback from pilot counties: Porter, Jasper, etc.

Indicators on: Assessed value; employment levels; prominent industry sectors; labor force; social dimensions; diversification index

Geocortex – Strengths and Weaknesses Weaknesses

Relatively new product Some documentation and an internet-based support forum

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!!!
