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. ” Definition: (The Practice of Local Government, C. J. Hoch and L. C. Dalton (eds. ), 2000, pg. 24)
Planning Process Vision & Objectives Inventory & Analysis Evaluation Alternative Strategies Implement
Objectives n Improve the development and implementation of comprehensive planning. n Incorporate process. GIS into this planning n Use the university’s research and outreach to assist a user in making a decision. n Implement a 3 -5 click framework.

Land Use/Land Cover n Land Use n Definition: of land” n LDM “Human-oriented use website n Importance n Development resources n Land tied to community’s land use maps typically used as base map for planning*
Land Use/Land Cover n Definition: “Discernible vegetation, geologic, hydrologic or anthropogenic features on the planet’s land surface” n Global Land Cover
Land Use/Land Cover n Data Availability n Land Use Mapping n Limited n Land or non-existent Cover n National Land Cove Data (NLCD) – USGS n 1992 (30 m) n 2001 (30 m) n Cropland Data – NASS n 2000 -2003 (30 m) n 2006 -2007 (56 m)
Land Use/Land Cover n Data Availability, con’t n Aerial Photography n 2005 Indiana Statewide Digital Orthophotography Program n 6 and 12 inch Natural Color n 1 -meter Color n National (NAIP n Agricultural Imagery Program 2003 -2007
Land Use/Land Cover Value Added Data • Land Cover Change (1992 -2003) • • • Conversion of 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
Land Use/Land Cover Value Added Data (cont’d) • Open Space/Working Lands Layer • • Based on 2003 NASS Data Urbanized Areas • • • Census 2000 Data Impervious Surface (USDA) Working Lands • • Used in a productive way Contribute harvestable resources • farmland • forests • grazing lands
Economic Development n Many comprehensive plans include economic development n LDM provides tools for benchmarking n Snapshot of GIS-based local & regional economic data n An opportunity to study economies at a regional scale
Economic Development n Value added: n n Research on useful indicators n n Research on various sources of public economic data 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 n Strengths n Improved n “Out web interface of the box” functionality n Printing PDFs n Quick View – drop down menus for location n Tools n Advanced n External Map Visualization - Google, Yahoo
Geocortex – Strengths and Weaknesses n Strengths, con’t n Tools n Advanced n n n External Map Visualization - Google, Yahoo Extract/Upload Data Markup n n Add points, text, symbols, grid, XY locations Selection n Query, filter n Select by…rectangle, line radius
Geocortex – Strengths and Weaknesses n Relatively new product n n Some documentation and an internet-based support forum Reliant on Arc. IMS axl file n. A broken connection from axl to database(s) causes a failure in Geocortex – no site! n Miss-coding in axl file also results in loss of map service.
Wrap-up Map service built into LDM is extremely powerful. n All you need is a computer and an internet connection. n Our integration of Phase 1 (Inventory/Analysis) and the map service is well underway. n Other parts of the decision system planned over the next 2 to 3 years. n We need feedback!!! n
