May 9, 2013
The purpose of this data documentation file is to assist the user by explaining attribute
information, and other data elements contained in the metadata and attribute tables.
The TIGER/Line Shapefiles contained in the CCGeoportal Geodatabases are extracts of public
data collected from the United States Census Bureau; the original data and technical
documentation can be found at:
http://www.census.gov/geo/maps-data/data/tiger.html.
TIGER/Line Shapefiles were used to create the following extracted shapefiles:

NuecesEdges
Nueces County, Texas All Lines 2013
The NuecesEdges (aka “All Lines”) shapefile contains visible linear feature edges such as
roads, railroads, and hydrography, as well as non-feature edges and non-visible boundaries.
The shapefile contains the geometry and attributes of each topological primitive edge.
Each edge has a unique TLID (permanent edge identifier) value. The edge’s left and right faces
can be identified by the TFIDL (permanent face identifier on the left side of the edge) and TFIDR
(permanent face identifier on the right side of the edge) attributes which link to the TFID
attribute in the Topological Faces shapefile.
CCGeoportal
http://corpuschristigeoportal.weebly.com/
The left and right side of an edge is determined by the order of the points that form the
edge. An edge is oriented from the start node to the end node. If one is standing on an edge at
the start node facing the end node, data listed in the fields carrying a right qualifier would be
found to the right of the edge. Data users can employ GIS software to plot the edges as
directional vectors with arrows showing the orientation of edges.
In the MAF/TIGER database, edges may represent several types of features. The series
of indicator flags (HYDROFLG, ROADFLG, RAILFLG, and OLFFLG) indicate the classes of features
that share the edge. For example, a road may have embedded tracks; the corresponding edge
will have both the ROADFLG (road feature indicator) and RAILFLG (rail feature indicator) set.
Generally, certain feature types appear together on the same edge:
Road and Rail—roads with adjacent tracks, tracks embedded in roadways or tracks located in
the median
Rail and Other Linear Feature—rail features located on dams and levees
Road and Other Linear Feature—road features located on dams and levees
The MAF/TIGER feature class code (MTFCC) identifies the specific code for the primary feature
on the edge. For edges that represent roads in combination with other features, the MTFCC in
the Shapefile will reflect the road feature.

NuecesLandmarks
Nueces County, Texas Current Point Landmarks 2013
The Census Bureau includes landmarks for locating special features and to help
enumerators during field operations. Some of the more common landmark types include area
landmarks such as airports, cemeteries, parks, mountain peaks/summits, schools, and churches
and other religious institutions. The Census Bureau has added landmark features on an asneeded basis and made no attempt to ensure that all instances of a particular feature were
included. The presence or absence of a landmark such as a hospital or prison does not mean
that the living quarters associated with that landmark were geocoded to that census tabulation
block or excluded from the census enumeration.

NuecesMilitary
Nueces County, Texas Area Military Installations
In 2012, the Census Bureau obtained the inventory and boundaries of most military
installations from the U.S. Department of Defense (DOD) for Air Force, Army, Marine, and Navy
installations and from the U.S. Department of Homeland Security (DHS) for Coast Guard
installations. The military installation boundaries in this release represent the updates the Census
Bureau made in 2012 in collaboration with DoD.

T2013NuecesPrimSecRoads100MileBuff
Primary and Secondary Roads within a 100 Mile Buffer of Nueces County, Texas
Primary roads are generally divided, limited-access highways within the interstate
highway system or under State management, and are distinguished by the presence of
interchanges. These highways are accessible by ramps and may include some toll highways. The
MAF/TIGER Feature Classification Code (MTFCC) is S1100 for primary roads. Secondary roads
are main arteries, usually in the U.S. Highway, State Highway, and/or County Highway system.
These roads have one or more lanes of traffic in each direction, may or may not be divided, and
usually have at-grade intersections with many other roads and driveways. They usually have
both a local name and a route number. The MAF/TIGER Feature Classification Code (MTFCC) is
S1200 for secondary roads.
