Re: [CTPP] UA conversion

by Dan Seidensticker

Hi Kendis, The formatting for the records in the UA TIGER files are a little different than the previous release so you won't get the correct results using the TIGER tools in Arc 8. If you do convert the UA TIGER files with ArcTools you will notice that the first 4 of the 5 digits for the 2000 UA Code end up in field UA90 and last digit in UR90. You can see why this happens if you compare the formatting of the ArcInfo result for Record Type A to the Census Documentation for Record Type A (Chapter 6, p.12). In other words UA90+UR90=UA. So, you can get a look at the Urban Areas if you relate Record Type A to the Census Geography using CENPOLID and concatenate fields UA90 and UR90. But I personally am going to hold off doing much more work with the UA TIGER files until ESRI updates the conversion tools. I'm sure there are other formatting changes that I'm not aware of. ---------------------- GIS Trivia Question: The GIS software maker Idrisi was named after: Galaxy Cartographer born 1099 A.D. in Morocco Their CEO's son A city in Egypt ____________________ Dan Seidensticker GIS Specialist Madison Area Metropolitan Planning Organization, City of Madison Planning Unit 121 S.

Re: [CTPP] Thanks!

by Sweson Yang

I used Maptitude's TIGER/Line Import function without any problem. The TIGER Version is 2000. Feature to import is "Census Urban Areas." I converted the projection to NAD83. Now, I have to join all 9 Counties together and get pertinent Census 2000 Block or Block Group demographics for further analysis. I would welcome any suggestions as to steps for doing this and procedures and considerations for revising the Metropolitan Planning Area. Thanks.

It looks like the converter I used is the problem. I will have to follow up with one of the alternatives many of you suggested.

Mapping urbanized areas and urban clusters by block ...

by Ben Mauldin

I've used the following method which uses some custom programs written by Warren Glimpse of Proxityone (www.proximityone.com) Here's a breif description: Though there are many ways to develop such a file, here is one method. The UAC and geocode hierarchy to get to the block level are contained in the composite of Census 2000 UA TIGER/Line files 1, A, and I. The appropriate TIGER/Line files can be downloaded from the Census server and processed with the Proximity TGR2DBF software creating a dbase structured version for these three TLFs. Next use TGR2DBF to create a census block-to-UA/UC code equivalency file (BLKUA.DBF). Next acquire the county by census block shapefile(s) from the Proximity map files website. Use the Proximity Cen2Shp software to merge the UA/UC code from the BLKUA.DBF into the county by block shapefile dbf. The augmented shapefile is now ready to support a display (or data link) of census blocks by user selected UA/UC. View the results of this process for the Lawrence, Kansas metropolitan area at http://proximityone.com/urbrural.htm Goto: http://www.proximityone.com/cen2000.htm#tigerua for more details.

Re: [CTPP] UA TIGER/Line files now available

by LESLEY HEGEWALD

I am having similar issues. I converted the files using the 2000 Tiger conversion tool in the ArcToolbox in Arc8. When I do this, the resulting files do not contain the UA field. I placed a call to the Census Bureau's geography department today, and was told that they have already heard of this happening and they suspect that it is due to the converter. They were not able to offer any help, but told me to go back to the software vendor. I am now trying to find someone at ESRI who can answer some questions. Has anyone else found a way around this?

I have downloaded the data and converted it in Arc View 3.2a with a Tiger Reader from the ESRI web site. But the closest thing to an "Urban Area" for 2000 is the "Transportation Planning Area." Any help?

Urban Clusters on UA/TIGER/Line

by Chuck Purvis

TO: CTPP-News This is probably a Bob LaMacchia question (Census Geography) but I'll post it to the CTPP-News since it may be of interest to many MPOs. Are the "Urban Cluster" boundaries included on the soon-to-be-released UA/TIGER files? The Bureau's web page (below) says yes, but I can't find a variable field for urban clusters in the PDF-formatted "record layout." http://www.census.gov/geo/www/tiger/tiger2k/ua_struc.html Or, are urban clusters and urbanized areas use the same "UA" code on the TIGER files? (And, if they use the same UA codes, is there any other indicator to use to separate by UAs from my UCs? I've got 13 urbanized areas and an additional 12 urban clusters in my region, which is manageable if I want a manually separate urbanized area versus urban cluster GIS layers....) (Urban clusters are smaller urban populations of 1,000-49,999 population, and apparently > 1000 persons per square mile. They include such places as Calistoga and Half Moon Bay in the Bay Area, and many of our California state prisons....) (WARNING: ESRI's web site www.geographynetwork.com DOES have TIGER 2000 data files in SHP format, but the "urban areas" that are included on their site are the 1990 URBANIZED AREAS, not the 2000 UAs!!! If ESRI staff are monitoring this listserv, you may want to clarify what is currently available, and when the 2000 UAs will be available on geographynetwork.com.) Thanks in advance!

urbanized area update

by ed christopher

the census bureau's web site dealing with urbanized areas and urban clusters is up and running. on may 3rd the TIGER files with the boundaries will also be available for downloading. http://www.census.gov/geo/www/ua/ua_2k.html FHWA and FTA have also posted a FAQ dealing with boundary issues and their implications. http://www.fhwa.dot.gov/planning/census/faqa2cdt.htm ======== Ed Christopher Metropolitan Activities Midwest Resource Center Federal Highway Administration 19900 Governors Drive Olympia Fields, Illinois 60461 708-283-3534 (V) 708-283-3501 (F)
