GIS Training at ARC• ARC has upgraded to the ArcGIS Desktop 9.3 curriculum

• New course outlines, lectures and exercise books• Currently offering ArcGIS Desktop I and II • May add Desktop III next year

• Registration is handled through ARC’s Community Planning Academy • Next class will be ArcGIS Desktop II: Tools and Functionality on March

4-6 • Email class announcements for Desktop II will be going out soon• 3 day class, cost is $340, available to local government staff only (city,

county, water authorities, transit agencies, etc.)• Class size limited to 12 • Please contact Paul DiGirolamo at 404-463-3520 or

pdigirolamo@atlantaregional.com for more information• Check the Community Planning Academy page of ARC’s website for

upcoming classes and online registration

• Considering adding a Spatial Analyst class, wanted to gauge interest, please let us know if that is something that would be useful

application – Geocortex Essentials Training in

Charlotte

• PECAS − Production Exchange Consumption Allocation

System− Developed by Drs Doug Hunt and John Abraham of

University of Calgary− I-O economic model approach − Two Modules, run Sequentially and Annually

• Activity Allocation (HH and Jobs) Module• Space Development Module

− 78 LUZ zones for 20-County model− Landuse forecast− Small area population and employment forecast− Generate input for Travel Demand Model

PECAS Modeling Progress

• SD Progress– Build rent equations for Fulton– Build Space Synthesizer for 15 counties– Evaluation and Calibration of Initial

Results from Synthesizer Runs– Migrate SD to PostgreSQL

PECAS Modeling Progress

PECAS Modeling Progress

• AA Progress– Initial Integration with Travel Demand Model

(Skims)– Unconstrained Run in June of 2008– Beginning of 2nd Stage Calibration (Imports

and Exports; Option Sizes)– Development of Constraint Values (Jobs,

Households by Income, Imports/ Exports)– Constrained AA Run October 2008

PECAS Modeling Progress

• Data Development Progress– PUMS ,IMPLAN, SF3 Data Development

for Use with AA– Employment by PECAS category

(industry by occupation by space type)– Development of Space Constraints

Using NAICS Employment and LandPro

PECAS Modeling Progress

• In 2009– Build Synthesizer for remaining 5

counties– Standardize zoning and density layer– Recode ARC SD model– Code rent equations into SD– Floorspace quantity adjustment– Establish Transport Cost Coefficients– Revise Design Diagram– Start calibrating prices from AA

PECAS Modeling Progress

TAZ Disaggregator• What is TAZ-D?

- ArcMap Extension- Spatial Analyst - Developed By PBS&J

TAZ Disaggregator

• What will TAZ-D do?– TAZ level data for Travel Demand Model – Disaggregate future forecast to Super

Districts (78) and TAZs (2024)• -landuse -employment• -household -population

– Improve ARC Zapping procedure• replace FORTRAN programs • Incorporate geospatial factors vs. existing

share based

TAZ Disaggregator

• Major Input data:– REMI forecast– Landpro – Street centerline– Travel impedance matrix– Transit– Parcels– Any geospatial factors

TAZ Disaggregator

• How does TAZ-D disaggregate…?– Apply factors and weighted scores– Spatial Analyst & raster conversion– Calculate and rank the likelihood of

development– Calibration– Allocate the future development– Make animation

TAZ Disaggregator

• Output – At Super District and TAZ level:

• Future employment by 21 NAICS categories• Population• Household by 4x6 HHInc Size categories

– Animation of future development• Progress

– Working on redevelopment module– Will test the full function and calibration

in next two weeks
