Title: Tele Atlas Dynamap /2000

Originator: Tele Atlas

Abstract:

The Service Center Agencies have purchased licensed use of the Tele Atlas Dynamap /2000 database by headquarters, state, and county employees. The database contains several attributed geospatial datasets for supporting USDA program business needs.

The licensing agreement with Tele Atlas allows the Service Center Agencies to use the database for any purpose including address geocoding. The Data can be used freely by the licensed agencies, but cannot be distributed to external organizations or the general public. Hard copy maps created using the data can be distributed freely, but must indicate that Tele Atlas Dynamap data were used in the map.

The database is a vector based, digital, nationwide geographic database. The database contains addressed and un-addressed street segments as well as highways, railroads, airports, point features (ex. churches, schools, public buildings, hospitals), and water features. It also contains Census and Postal ZIP layers, parks, county and state boundaries, cities, area landmarks, places and major retail locations.

The majority of data in the product is taken from the TANA/GDT core internal database, which contains nearly every street in the nation. TANA/GDT continuously builds and updates this core streets database that contains addresses, through a constant blending of geographic data from many verified sources.

Many of the data feeds are from official government sources such as; the U.S. Census Bureau, the U.S. Postal Service, and the U.S. Geological Survey. TANA/GDT has also established working relationships with counties across the U.S. as well as most cities, towns, and chambers of commerce. TANA/GDT maintains relationships with state departments of transportation, state and regional GIS departments, and many other state, regional, and local governmental agencies. TANA/GDT relies on relationships with more than 33,000 resource providers, strategic development partnerships, and data enhancement feedback loops for baseline data sources.

The Service Center Agencies' Geospatial Data Management Team selected 21 layers for delivery through the Geospatial Data Gateway SCA standard file naming conventions.
