Name: Transit_GRTA Source: Georgia Regional Transportation Authority (GRTA)Date: 2005Extent: 10+ CountiesFeature: LineScale: 1:24,000Description: This Layer was compiled by GRTA to support the annual submission of transit route information to the Federal Transit Administration (FTA) for inclusion in the National Transit Database (NTD). This Layer was created using ARC's streetbase, ARstreets as a base map where GRTA's "Xpress" service bus routes were "trace" digitized on-screen over ARstreets road segments or photo-interpreted from 2003 digital orthophotography (Aerials Express, Inc.). This Layer currently reflects "Xpress" routes in service as of December 31, 2005 and is generally updated annually during the first quarter of each calendar year. For more information, go to http://www.xpressga.com. Please note, there are a total of 5 (bus) transit Layers on this CD including CCT, Ctran, GCT, GRTA and MARTA. The geographic extent of this Transit_GRTA Layer is the 13-county Atlanta region with the exception of Paulding and Fayette counties.Attributes: RTE_ID Bus route numberRTE_DESC Bus route description
