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
