MOBILITY FUND PHASE I AUCTION

GIS DATA OF POTENTIALLY ELIGIBLE CENSUS BLOCKS

AU Docket No. 12-25
1. By this Public Notice, the Wireless Telecommunications and Wireline Competition Bureaus
(the Bureaus) announce the availability of geographic information system (GIS) data for the census
blocks potentially eligible for Mobility Fund Phase I support to be offered in Auction 901. This data does
not update or replace the list of potentially eligible blocks. Rather, it provides the same data in additional
formats and thus just supplements the previously-released data files and interactive map. We are taking
this step to make the data accessible to more people and to make it easier to use for individual analysis.
2. In the Auction 901 Comment Public Notice, the Bureaus concluded that we would identify
census blocks eligible for the Mobility Fund Phase I support to be offered in Auction 901 based on an
analysis of the most recent available American Roamer data, from January 2012.1 With the Auction 901
Comment Public Notice
, we provided a preliminary list of such blocks using older American Roamer data
and stated that we would provide an updated list of potentially eligible census blocks and related updated
information upon completion of our analysis of the January 2012 American Roamer data.2 With the
Auction 901 Updated Potentially Eligible Blocks Public Notice, we provided the updated list of
potentially eligible blocks based on January 2012 American Roamer data in electronic format as
“Attachment A” files.3
3. Concurrent with the release of Auction 901 Updated Potentially Eligible Blocks Public
Notice, the Bureaus announced the availability of a map of the updated potentially eligible blocks. The
map is an interactive visual representation of data from the updated Attachment A files. The Attachment
A files contain more information and generally more detail than is displayed on the map. The map is
available at http://wireless.fcc.gov/auctions/901/ and at http://www.fcc.gov/maps/.
4. The data formats we make available are additional formats of the data as shown in the
interactive map. These formats, which are available at http://wireless.fcc.gov/auctions/901/, are the
following:
·
downloadable shapefile
·

5. The shapefile format is actually four individual files (.dbf, .shp, .shx, and .prj) all with the
same prefix.4 This format is generally recognized as a standard transfer file for GIS data. The shapefile
is an accepted transfer in just about every GIS software package.
6. Web mapping service (WMS) is an Open Geospatial Consortium standard for delivering
geospatial data over the web.5 The WMS data service can be viewed in two ways. First, the data can be
viewed by using the URL. Second, most GIS software allows you to add this service as a layer to your
session or project.
7. MapBox map tiles are cached map tiles of the data. With this open source software approach,
these image tiles can be joined with other MapBox layers to make new maps.6
