[CTPP] Join us for "CTPP Data Access Software Basics"

by Weinberger

Hi all, Please join us for CTPP Software Basics on one of the three dates below. Seating is limited and first come first serve. This is a basic introduction to the CTPP data access software and functionality. You will learn how to register/log in, how to access a table, how to manipulate data, or move/swap dimensions within a table, how to download the data and more. If you like, you may first go to: http://ctpp.transportation.org/Pages/3yrdas.aspx and click on “take me to the data” to create a user profile and “poke around” a bit. Register and bring your questions to one of the three trainings below. See you there.

[CTPP] 2010 Census UA Criteria

by Brooks

Texas Transportation Institute: Transit Mobility Program has been applying the Census 2010 UA Criteria released on August 24, 2011. We have been assisting the TxDOT Public Transportation Division in their efforts to anticipate the impacts of UA and UC changes. A co-worker and I have been conducting analysis on specific urban clusters/areas as per TxDOT's needs for anticipating the impact of changes on transit formula funding. I have spoken with some contacts within the Census Geography Department and am confident I have a good grasp of data sources and interpretation of the criteria. However, the analysis we have done has not been via a script or code in GIS. We have been manually applying certain steps of the criteria, such as the changes relating to impervious surface, to augment some recent statewide research we had already completed (we projected 2010 UAs several years ago). I think that Martin Catala at CUTR may have a student now working on a script and code for the criteria. Anyone interested may contact me to discuss TTI's process and findings.

[CTPP] Reminder: Tuesday, Oct 11 at 1:00 - 3:00 p.m EASTERN, WEB-Training on American FactFinder 2 conducted by Census Bureau

by Elaine.Murakami＠dot.gov

As of today, about 150 people have signed up for the October 11 webinar, so there is still room for you! This webinar will focus on AFF2. Please use the link below to register for the session. I have reserved 220 spaces. https://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_re g.aspx?webconfid=23454 After you register, you will get the meeting URL and the telephone number. Ed Christopher from the FHWA Resource Center Planning Team is responsible for running the session. His email address is edc(a)berwyned.com (he prefers using this email address to his official USDOT email address). Michelle Jiles on the Census Bureau's ACS staff will conduct the training. Michelle previously worked for the Census Bureau's Journey-to-work and Migration Branch, so she is familiar with the CTPP user community. I have asked her to cover examples using both tables from ACS and 2010 Census SF 1. She will mention but not provide training on the ACS system to download files. The Block Group data from ACS is not available via AFF2 but ONLY through the download system. If there is time at the end, she can discuss this more fully, or else, we will arrange for another training session. We will have plenty of time for questions and answers.

RE: [CTPP] Are you writing GIS code to estimate Urbanized Area Boundaries using 2010 Census

by christopher.j.henrie＠census.gov

Yes, this is the NLCD 2006 data that is being used to qualify urban territory according to a high degree of impervious land cover. The Census Bureau will only use the 2001 NLCD in areas where the 2006 vintage is not available (outside conterminous U.S.). According to the 2010 Census urban area delineation criteria, a census block qualifies for inclusion in an initial urban core if it is associated with a high degree of impervious surface cover and is compact in nature, or shares a significant boundary with qualifying territory. In order to identify this territory, the Census Bureau first extracts the NLCD cells with 20% or higher imperviousness. After a raster to vector transformation on the extracted cells is performed, the Census Bureau then intersects the polygons with the census blocks. If more than 1/3 of the area of the census block is impervious, the block is flagged as a potential impervious block. However, the census block must then meet the shape index or contiguity criteria in order to qualify as belonging to the initial urban area core. Please see the Federal Register notice for a full description of these criteria: http://www.census.gov/geo/www/ua/urbanruralclass.html The Census Bureau allows for the inclusion of non-compact census blocks because the Census Bureau found in testing a number of elongated census blocks with a high degree of imperviousness were associated with road medians that artificially separated qualifying territory. In some cases, the presence of these census blocks prevented further iterations of the initial core qualifying criteria effectively disqualifying territory that should have been considered urban. Thus, as described in the Federal Register notice, some interactive review is necessary to determine whether classification of the additional urban territory is appropriate during these additional iterations of the core building criteria enabled by the identification of these census blocks.

Does anyone know for certain if this is the NLCD impervious dataset that is being used in the criteria? http://www.mrlc.gov/nlcd06_data.php The Federal Register doesn’t go into much detail on how the percent impervious area data is used in the criteria. Is the impervious area translated to census block geography (raster to vector)? The footnotes in the register suggest some subjectivity which would could make it difficult to incorporate into code.

I found this is my email today from an undisclosed source. I would think that the data will only be released in Factfinder2 but I haven't heard anything for sure. If anyone on the list is part of the State Data Center network and knows more please let us know. For now I guess we will just have to wait and read about it in our newspapers. --------------- Sept 20, 2011: Media Webinar: 2010 American Community Survey 1-Year Estimates - at 3 p.m. EDT, the Census Bureau will hold a Web conference to discuss the Sept. 22 release of the 1-year American Community Survey estimates. The webinar will include guidance on how to access and use the upcoming 1-year estimates, a review of selected findings and a question and answer session. The Web conference will consist of a simultaneous audio conference and online presentation. Dial-in and access information will be announced closer to the date.

FW: [CTPP] 2010 1-year ACS due out Sept 22nd.

by Manny Trillo

This announcement came from the Census Bureau today. As you can see, it is for "Only members of the media who have applied for and received embargo access may join." Apparently the Census Bureau is not interested in releasing embargoed data to those of us who use it. The SCD network is apparently allowed to participate in these press releases/discussions/webinars, but not the affiliate network. I have repeatedly stressed that the local media, upon getting something like this, immediately calls us for the local slant. Of course, we have none because we don't have access to the data. Yes, you will have to wait and read it in your local newspapers or watch it in the local news.

[CTPP] HPMS Small Urban Area vs. Urban Cluster

by Hesselroth

Hello, I'm kind of new to this group and don't know if this topic has been covered before or if there are other HPMS folks on this list. This is a GIS technical question related to the population minimum of 2,500 for urban clusters and the population minimum of 5,000 for HPMS Small Urban Areas. The TIGER/Line shapefiles for boundaries for Urban Areas will be available in Spring 2012. We plan to use these shapes (after smoothing) to do a GIS "clip" of the roads within them to determine HPMS Data Item #2, Urban_Code. The HPMS Field Manual says that the Urban_Code value "is 99998 for small urban sections (not within the adjusted urbanized area and with an urban population of at least 5,000)." So I assume there will be a way to identify the Urban Areas in the shapefile by population so that we can remove those shapes with population between 2,500 and 5,000 before we do our geoprocessing for HPMS. Is this correct? Thanks!
