pdGeoTIGER utilizes only the ANSI character set (ASCII values 0 to 127 and extended values 128 to 255) and comes in multiple file formats to insure compatibility. It is well-matched with pdCensus2010 and employs U.S. Census Bureau coding conventions. The product is drawn from the most recent edition of the U.S. Census Bureau TIGER/Line® Shapefiles. The included postal coding is based on April 2014 USPS data. Updates are provided as warranted based on significant changes in information. While coverage is very high, the Shapefiles have gaps and limitations. There are address range overlaps, odd/even reversals, and low/high orientation reversals. With the exception of overlaps, these may be valid. Peacock Data has corrected most low/high orientation reversals. The Shapefiles generally contain only address ranges with structure number-street name style addresses and for privacy reasons does not include single address-address ranges.

Latitude and Longitude coordinates

Any location on Earth can be described with two numbers—its latitude and its longitude. If a pilot or a ship’s captain wants to specify a position on a map, these are the coordinates they would use. In actuality, these coordinates are angles, measured in degrees, minutes, and seconds of arc.

The database provides U.S. Census Bureau internal point latitude and longitude coordinates for Census Blocks and they are presented in multiple formats.

Internal point latitude and longitude coordinates are a calculated point that is at or near the geographic center of the entity. For some irregularly shaped entities (such as those shaped like a crescent), the calculated geographic center may be located outside the boundaries of the area. In such instances, the internal point is identified as a point inside the entity boundaries nearest or near the calculated geographic center.

The following are the three formats provided for each set of coordinates; the examples are for the same latitude and longitude in Apache County, Arizona.

Land and water area

Census Block total area size is entered in whole square meters, and the Block‘s land and water characteristics are identified with the following values:

Urban and rural indicator

Urban and rural characteristics are provided for Census Blocks. For the 2010 Census, the U.S. Census Bureau classified as urban all territory, population, and housing units located within urbanized areas (UA) and urban clusters (UC), both defined using the same criteria. The U.S. Census Bureau delineates UA and UC boundaries that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the “urban footprint”. Rural areas consist of all territory, population, and housing units located outside UAs and UCs.

For the 2010 Census, the urban and rural classification was applied to the 50 states; the District of Columbia (federal district); and the Commonwealth of Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands insular areas.

Urban/Rural coding is as follows:

Bonus pdGeoSupplement reference file

pdGeoSupplement is a companion file for pdGeoTIGER (as well as pdCensus2010 and pdACS2013) and is provided with the product downloads. It is an over 300,000 record proprietary, easy-to-use, comprehensive, and up-to-date United States national reference database for U.S. Census Bureau legal and statistical areas covered by Peacock Data GeoCoding, U.S. Census 2010, and American Community Survey (ACS) database products.

pdGeoTIGER and pdGeoSupplement make excellent partners. Most U.S. Census Bureau codes not in pdGeoTIGER are available in the supplement. These include:

And the following special indicators:

Because both products utilize the same U.S. Census Bureau coding conventions, once the main legal and statistical area designations are determined, it is a straightforward process to then apply the supplemental information.
