E-grāmata: Designing Geodatabases for Transportation

Designed for GIS professionals and those who manage transportation, this guide to scalable geodatabase design provides detailed instructions on how apply existing data to spatial data themes, use data modeling to adapt to changing requirements, and to keep historical data to analyze and compare data sets. Butler is a licensed contractor, certified planner and GIS professional, and he offers step-by-step instructions on how to design a geospatial information system that will effectively manage and process information on a wide variety of complex transportation systems through the use of data modeling and geometric networks. Different models of the UNETRANS network are also explained. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)

Designing Geodatabases for Transportation addresses the development of a GIS to manage data relating to the transportation facilities and service commonly organized around various modes of travel for accurate and reliable data exchange. Transportation involves several modes of travel, and although the details of each mode can be quite different, this book demonstrates how all follow a basic conceptual structure. That structure consists of an origin, a destination, a path between the two, and a conveyance that provides the ability to move along the path to establish a common data structure.
