Tiger Roads Data

Автор:

TIGER/Line Roads Data This section is focused mainly on the use of the TIGER/Line 'edges' shapefile. The edges shapefile U.S. Wall-to-wall street/road coverage in the form of line shapefiles. Lines classified as roads are intersection-to-intersection road segments. Line segment fields include name, left- and right-side high and low addresses. The TIGER/Line data cover the entire United States. Road features come with various attributes, including address ranges, the geographic relationship to other features, road classification, geometry length, street name, and ZIP code. The TIGER/Line data are provided in shapefile format which has been developed by ESRI, Redlands (CA).


The USGS Transportation downloadable data from The National Map (TNM) is based on TIGER/Line data provided through U.S. Census Bureau and supplemented with HERE road data to create tile cache base maps. Some of the TIGER/Line data includes limited corrections done by USGS. Transportation data consists of roads, railroads, trails, airports, and other features associated with the transport of people or commerce. The data include the name or route designator, classification, and location. Transportation data support general mapping and geographic information system technology analysis for applications such as traffic safety, congestion mitigation, disaster planning, and emergency response. The National Map transportation data is commonly combined with other data themes, such as boundaries, elevation, hydrography, and structures, to produce general reference base maps. The National Map viewer allows free downloads of public domain transportation data in either Esri File Geodatabase or Shapefile formats.

Streets TIGER 2015 AbstractThe Streets TIGER 2015 data set represents street centerlines acquired from the US Census Bureau.The TIGER acronym stands for Topologically Integrated Geographic Encoding and Referencing. PurposeStreet centerlines are widely used as a reference layer. The Census Bureau also uses the streets layer for delineating census blocks,and geocoding. Time Period of Content2015 Update Frequencyannual Publish Date2/2015 OriginatorUS Census Bureau PublisherUS Census Bureau Theme Keywordsstreet, highway Place KeywordsFlorida Source ScaleVaries: 1:12,000 to 1:100,000 Horizontal AccuracyVaries: The Census Bureau does accuracy tests using high-precision GPS at street intersections and documentserrors per county.

Not all streets have been re-aligned. Estimated accuracy range for re-aligned streets is +/- 23 to +/- 40 feet.Streets that have not been re-aligned can be over 300 feet off. Rural areas are more likely to be less accurate than urban areas.

The Census Bureau currently releases annual data updatesthat includes all improvements made in the previous year.on the Census Bureau website.
