A shapefile is a geospatial data format for use in geographic information system (GIS) software. Shapefiles spatially describe vector data such as points, lines, and polygons, representing, for instance, landmarks, roads, and lakes. The Environmental Systems Research Institute (Esri) created the format for use in their software, but the shapefile format works in additional Geographic Information System (GIS) software as well. 1.2 What are TIGER/Line Shapefiles?

Consequently the eJlectiveness of the current system is being 14 negatively impacted and is losing its ability to eHiciently serve as an alternate 1 1 mode of transportation. This is evidenced by the fact that ridership has declined 2 30% in the past 4 years. 3 I Liheslaturan Guahan additionally finds that in a December 2008 study, 4 jointly commissioned by the Federal Highway Administration (FHWA) and the 5 Department of Public \Yorks (DP\V) and which formed the basis for the 2030 6 Guam Transportation MasterPlan, the following findings were made.

This guidebook is intended to provide tribal governments and their transportation planning personnel, assistance in understanding the ADOT planning and programming processes and associated funding sources. ADOT is committed to working cooperatively with all tribal governments in Arizona to assure that critical transportation system needs are met on tribal lands. This Guidebook is organized to first provide background on the State Highway System and its relation to tribal lands and the ADOT engineering management districts. Second, it explains ADOT’s vision, mission, goals, and responsibilities in relation to management of the state transportation system. Third, it provides tribal governments with an overview of the ADOT planning and programming process for major transportation improvement projects. Finally, it provides a summary discussion of ADOT’s funding sources for transportation improvement. ADOT also has additional resources for tribal transportation funding available upon request. This second edition of the ADOT Transportation Planning and Programming Guidebook for Tribal Governments is not all inclusive of every detailed process used by ADOT; it is intended to provide tribal governments with a basic understanding of the current planning and programming processes as they relate to tribes.
