Re: [Maptitude] Urban Areas

[Kevin Byrnes]

Dr Dilger: I would suggest that you try to get a list of the traffic zones which make up the CBD as defined by the metropolitan planning organization (MPO) for each metro area.  Traffic zone boundary data can be extracted from the TIGER file using Maptitude.  Perhaps their is a summary table of comparative CBD data compiled by the Journey to Work staff at the Census Bureau or elsewhere in FHWA, UMTA or other federal agencies.  The Urban Transportation Planning Package (1990) data and Census Transportation Planning Package data (2000) may have the CBD summary data you need.

I am using the census place area to represent suburban development and I need a freely available type of geography to represent the city center. The urban areas I currently have do not seem to represent urban cores-or they do not have area size associated with them (I need to calculate population density). I’d appreciate any thoughts on this.   Fred C. Dilger PhD. (702) 290-6990   SPONSORED LINKS Geographic information systems Geography game Physical geography Geography game for kid Geography YAHOO!
