FEATURE ATTRIBUTE TABLES CODES AND VALUES:
Item | Item Description | |
OBJECTID |
Internal feature number. |
|
DYNAMAP_ID |
The unique segment identification number. |
|
L_F_ADD |
The address on the left side of a street segment at the beginning or 'from' end of the digitized segment. |
|
L_T_ADD |
The address on the left side of a street segment at the end or 'to' end of the digitized segment. |
|
R_F_ADD |
The address on the right side of a street segment at the beginning or 'from' end of the digitized segment. |
|
R_T_ADD |
The address on the right side of a street segment at the end or 'to' end of the digitized segment. |
|
PREFIX |
A 2-character field that is used to indicate a modifier to a street name occurring before the street name and usually indicating direction. Ex: 'E' Center St. |
|
PRETYPE |
This field supports new GIS geocoding technology, which allows for additional parsing of international names and highway names. |
|
NAME |
The concatenated full name of the street segment. |
|
TYPE |
The type of street. Some examples are ST, AVE, PKWY, etc. |
|
SUFFIX |
A 2-character field that is used to indicate a modifier to a street name occurring after the street name and usually indicating direction. Ex: Prospect Bay Dr 'W.' |
|
FCC |
The feature class code that the street segment is associated with. Tele Atlas(R) FCCs are similar to the Census Bureau's CFCCs used in their TIGER(R) files. |
|
POSTAL_L |
The enclosing 5-digit ZIP Code area on the left side of the street segment. |
|
POSTAL_R |
The enclosing 5-digit ZIP Code area on the right side of the street segment. |
|
ACC |
The set of Arterial Classification Codes (ACCs) is the Tele Atlas(R) system for categorizing roads according to the level of travel mobility that they provide in the road network. Mobility refers to the volume of traffic that a stretch of road carries and the length of trip that it serves. Valid entries are '1' for roads with highest mobility, through '5' for roads with least mobility. |
|
NAME_TYPE |
A 1-character field to indicate whether the street name can be used for geocoding or routing. Valid contents are: 'R'= primary routing name; 'G'= primary geocoding name; 'blank'= other. |
|
SHIELD |
The first character of the shield field indicates what shield should be used to represent each name based on its Primary Name. 'I' = Interstate, 'U' = US Hwy, 'S' = State Hwy, blank = other. The second character of the shield field indicates subclassifications of the shield type. A shield subtype should not exist if there is not a primary shield type in the first character of the field. Valid entries are 'B' for business route; 'L' for loop; 'T' for truck; 'C' for connector; 'S' for spur; 'Y' for bypass; 'A' for alternate; 'X' for extended; 'N' for scenic. |
|
HWY_NUM |
The Hwy_Num field indicates the number that appears in the shield for the highway. This will be present only for Interstates, U.S. Highways and State Highways. The HWY_NUM field will be populated only on FCC segments of A1*, A2* and A3*. |
|
SEG_LEN |
The highway segment length in miles. The distance is calculated using the arc distance with correction for the earth's curvature. |
|
SPEED |
The segment speed field contains the average speeds categorized by FCC and defined in a Tele Atlas(R) FCC-to-Speed table document. The units are in miles per hour. |
|
ONE_WAY |
The One_Way field is filled with either 'FT,' 'TF' or is blank. 'FT' indicates that the segment is one way, from the digitized From end to the digitized To end. 'TF' indicates the opposite direction of travel. A blank field indicates that travel is permitted in both directions. |
|
F_ZLEV |
This field indicates the Z-axis relative elevation of a segment in the digitized 'From-to' direction. '0' indicates ground level; '1' indicates structures elevated one level above ground; '-1' indicates structures one level below ground level, etc. |
|
T_ZLEV |
This field indicates the Z-axis relative elevation of a segment in the digitized 'To-from' direction. '0' indicates ground level; '1' indicates structures elevated one level above ground; '-1' indicates structures one level below ground level, etc. |
|
FT_COST |
The cost to travel on a segment in the digitized From-To direction. The value of the cost is based on the length of the segment and its speed value. The units of cost are minutes. In some GIS formats, a '-1' value is a code that indicates that the street contains an alternate name. |
|
TF_COST |
The cost to travel on a segment in the digitized To-From direction. The value of the cost is based on the length of the segment and its speed value. The units of cost are minutes. In some GIS formats, a '-1' value is a code that indicates that the street contains an alternate name. |
|
FT_DIR |
The FT_Dir field conveys information about the described direction of travel along highways in the digitized From-to direction. This directional is not part of the recognized postal name. Permissible values for this field are N, S, E, W, NE, SE, NW, SW. |
|
TF_DIR |
The TF_Dir field conveys information about the described direction of travel along highways in the digitized To-from direction. This directional is not part of the recognized postal name. Permissible values for this field are N, S, E, W, NE, SE, NW, SW. |
|
NAME_FLAG |
For the Street layer in this product, this field is a coded indicator of whether a street name is most appropriate for statewide or cross-country routing (field content = '1'); whether a street name is most appropriate for geocoding (field content = '2'); and whether the routing name is also appropriate for geocoding purposes (field content = '3'). |
|
STATUS |
A one-character field relating to a street's category. |
|
DESCRIPT |
Description field based on PREFIX, NAME, TYPE, & SUFFIX |
|
FGDLAQDATE |
FGDL added field based on date downloaded from source |
|
SHAPE |
Feature geometry. |
|
AUTOID |
Unique ID added by GeoPlan |
|
SHAPE.LEN |
Length in meters |
Tests are performed for invalid names, Feature Class Codes and characters. Tests are constantly running on the Tele Atlas(R) database to ensure segment topology meets Tele Atlas(R) specifications. The Streets layer is not generalized. |
All street segments in the Tele Atlas(R) database with an FCC = A* are considered. A74 (driveways) and A75 (parking areas) are not selected. After processing, the dataset is checked for drawing display, correct number of records, record schema consistency with specifications, correct file naming, file sizes and a comparison check with the contents of the Tele Atlas(R) database at the time of creation. |
GeoPlan relied on the integrity of the attribute information within the original data. |
To find out more about Dynamap(R)/Transportation and other available products, visit http://www.teleatlas.com. |
The primary purpose of the Dynamap(R)/Transportation Street layer is for mapping and geocoding street addresses. When used in conjunction with other Dynamap(R)/Transportation layers, the street layer can be used for site selection, territory management, risk management/assessment, emergency response and other business and government needs. |
Tele Atlas(R) street segments allow for six implied decimal places of precision. While minimum accuracy is consistent with 1990 TIGER/Line(R) files, accuracy is dependent on geographic area and sources used to update those areas. Nationwide, over 20 million street segments are horizontally accurate to 12 meters or better. |

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
