Identification_Information: Citation: Citation_Information: Originator: Tele Atlas(R) Publication_Date: 200710 Title: DTrans_ssxxxxst: Streets Edition: 9.3 Geospatial_Data_Presentation_Form: Vector digital data Publication_Information: Publication_Place: Lebanon, NH Publisher: Tele Atlas(R) Other_Citation_Details: Data file format ssxxxxst: ss=State abbreviation; xxxx=County abbreviation (if tiled by county); st=Street layer abbreviation. Note: Some Dynamap(R)/Transportation GIS formats may have other file naming conventions for this layer. Description: Abstract: The Dynamap(R)/Transportation Street layer contains all streets in the Tele Atlas(R) database with a Feature Class Code (FCC) of A1*, A2*, A3*, A4*, A5*, A6* and A7*. Driveways (FCC = A74) and parking areas (FCC = A75) are excluded from the dataset. The Street layer in all GIS output formats contains address, name, FCC and ZIP Code attribution. The Dynamap(R)/Transportation Street layer contains over 20 million named and addressed street segments in the U.S. and Puerto Rico. Purpose: 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.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Street data is crosschecked and verified using numerous independent mapping sources. More than 500 algorithmic QC checks are applied against the database to ensure that changes to geography and attribution conform to the Tele Atlas(R) internal Database Feature Modeling Specifications. Logical_Consistency_Report: 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. Completeness_Report: 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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. Lineage: Process_Step: Process_Description: Tele Atlas(R) extracts the dataset quarterly from the Tele Atlas(R) database using proprietary software. Data then is converted into multiple GIS formats. ISO quality standards are enforced throughout the production process.

Note that certain GIS formats may have additional attribution. Refer to the Entity and Attribute Detail Citation in this document to access more detailed information on street and highway attribution. * 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. * Name: The concatenated full name of the street segment. * Type: The type of street. Some examples are ST, AVE, PKWY, etc. * Pretype (ArcView and Database-Loadable formats only): This field supports new GIS geocoding technology, which allows for additional parsing of international names and highway names. * 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.
