The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The All Roads Shapefile includes all features within the MTDB Super Class "Road/Path Features" distinguished where the MAF/TIGER Feature Classification Code (MTFCC) for the feature in MTDB that begins with "S". This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

The Babbitt Center for Land and Water Policy, a center of the Lincoln Institute of Land Policy, has released a comprehensive, peer-reviewed map of the Colorado River Basin that showcases the area’s geography and hydrography while addressing inconsistencies found among current maps of the region. The map also includes a narrative history of the basin, and it highlights crucial concerns facing the region. It will provide an updated resource to stakeholders in the Colorado River Basin as they chart a sustainable path forward for the Colorado River, which supports over 40 million people across the United States and Mexico and irrigates 4.5 million acres of agriculture.The Babbitt Center produced the printed map in partnership with the Lincoln Institute’s newly launched Center for Geospatial Solutions, which harnesses data to inform decision making related to land and water management. The full-color, double-sided map highlights specific regions and issues of note in one of the fastest-growing areas in the United States. Features include:A physical and political map of the entire Colorado River Basin, including the location of the 30 federally recognized tribal nations in the basin; structures such as dams, reservoirs, transbasin diversions, and canals; protected areas; and indications of whether streams are perennial or intermittent.Inset maps spotlighting wildfire risk, the Colorado River Delta in Mexico, the shrinking Salton Sea, and the relationship between urban development, irrigated agriculture, and water management in major cities.Stunning photographs of the Colorado River headwaters and Delta, Lake Powell, the Imperial Valley, and other significant landmarks of the region.Narrative explorations of key issues in the Colorado River Basin, including climate change, tribal water rights, wildfire, development, agriculture, and biodiversity.Historical information on the division of water among the U.S. states and Mexico and the drought contingency negotiations that have occurred during the first two decades of the 21st century as climate change threatens significant streamflow losses."Click here to learn more at the Lincoln Data Website"
