FRAMEWORK FOR A REGIONAL DECISION SUPPORT SYSTEM
PRESENTATION OVERVIEW• Project Overview
• Project Partners
• Why a Regional Decision Maker
• Subject Areas (online demo)
• Demographics, Transportation, Occupation and Industry Clusters, and LULC
• Tools
• Custom Region Summary
• Variable Weighting Tool
• Pros & Cons
• Web or Desktop
• API choices
• Future Work
• Originated from Local Decision Maker Project
• FNR, PCRD, Sea Grant, C4E
PROJECT PARTNERS
WHY A REGIONAL DECISION MAKER?• Think Globally, Act Locally
• Regionalism
• Environmental, Economic, Social issues do not stop at man-made borders
• Research based outreach projects including:
• Occupation and Industry Clusters
• Transportation
• LTM USGS
• Think Regionally Succeed Locally ………..…..………..Tehachapi News, www.kerncog.org
An emerging paradigm is-
TECHNOLOGY• ArcGIS Server 10
• Web apps using FLEX API
• ArcSDE Database
• Why these choices?
DESKTOP OR SERVER?
• Qualitative and quantitative information can be mapped together• Increase or decrease is qualitative whereas population size for 2009 is
quantitative information
• Desktop mapping can do the multiple attribute mapping
DESKTOP OR SERVER?• Multiple attribute mapping through ArcGIS Server could be challenging
• ArcGIS 10 (Arc Map) has a map service publishing toolbar
• Analyze tool can flag the problem areas, selected features from a layer, viewable at all scales
• Preview tool can show how it will look on the web and how much time it will take to display
• Multiple attribute mapping is not supported
• You need to create a separate layer/feature class on Arcade for each of the qualitative classification
• We are not using MSD but the cleaned and optimized MXDs- ArcGIS Server Manager
SUBJECT AREAS
• Demographics
• Transportation
• Occupation and Industry Clusters
• Land Use Land Cover forecasts
DEMOGRAPHICS• County-based
• Place-based
• Annual Population Estimates, Census
• American Community Survey, 2005-2009
• Decennial Census
DEMOGRAPHICS• Population
loss/gains
• Patterns of population change
• Rural areas are losing
• Metropolitan areas- central cores are
losing, first suburbs are losing, suburbs,
and some exurbs are gaining
NATIONAL TRANSPORTATION ATLAS DATABASE (NTAD)
• Annual update
• Boundaries- MPOs, urbanized areas, military bases, parks
• Facilities- Airports, runways, water ports, Amtrak stations, transit stations
• Intermodals by modes
• Networks- NHPN, railways, navigable waterways, transit link (all types)
• Other- Alternative fuel stations, automatic traffic recorders, railways-highways crossing
• Non attainment areas by criteria pollutants
FREIGHT ANALYSIS FRAMEWORK
• Movement of goods
• AADT
• AADTT
• Forecasting
• Incorporates commodity flow surveys,
border crossing data
• Modeled values of speed, delays, VCR,
etc.
OCCUPATION AND INDUSTRY CLUSTERSTotal Employment, Dot-density
OCCUPATION AND INDUSTRY CLUSTERSKnowledge-Based Occupations, Dot-density
Engineering; Mathematics, Statistics, & Data; Natural Sciences & Environment; Health Care & Medical Science; etc.
LULC CHANGE
TOOLS
• Part of modeling component of spatial decision support system
• Based on geoprocessing tools from AGS
• Each tool answers a specific question
REGION SUMMARY TOOL
• Summarizes data based on user-defined area
• Example: employment occupational clusters for each county in US
• The tool will sum employment for all counties that are selected by user interactively

VARIABLE WEIGHTING TOOL
• Overlays several maps into one based on weights assigned by user.
• Can take vector and raster maps as inputs
• All maps have equal weight by default (value of “1”)
• Can use any weighting scale
• verbal, e.g. “poor-excellent”, “low-high”;
• Numeric, e.g. “-5 to +5”, “0 to 5”
• These models can be theme specific (e.g. environmental only) or can combine data from different areas (e.g. economic, demographics, land use, etc.)
• Useful when looking at different scenarios of development or prioritizing areas for development
VARIABLE WEIGHTING TOOL – THE MODEL
TIPS AND TRICKS
• Build model to answer a specific question: good decision support system should be intuitive and simple to use
• Have detailed metadata or map description available for advanced GIS users
• Keep models simple to improve processing time, preprocess maps if needed
• Use relative paths when creating models in Model Builder
• Get ArcSDE database well organized (naming, metadata)
• Have metadata or description readily available for user to see along with the map
• Easy to get data online
FUTURE
• What does a Regional Decision Maker look like?
• How do the pieces we just preview fit in?
CONCEPT National Decision National Decision Maker Portal Maker Portal ArchitectureArchitecture
MOVING FORWARD
• Decision trees
• Develop more complex models to answer more complex questions.
• a survey-style questionnaire that helps user answer specific questions regarding planning
• For example, identify development strategies based on current environmental and economic characteristics of AOI and development preferences. The questionnaire can use “Yes-No” and/or multiple-choice format questions.
• Can provide answer in a verbal and/or spatial (mapped) form
CONCLUSION
• Adobe Flex API with ArcGIS Server
• Presented data from research projects
• Variety of ways for user to view and interface with data
