简介
"When local governments decide to go digital and use a geographic information system (GIS) to store and access information, many tasks need to be done. ArcGIS and the Digital City: A Hands-on Approach for Local Government provides step-by-step exercises using real data with ArcGIS that take you through the process of building and using GIS data in a local government." "Containing the authentic nuts and bolts of daily GIS activities, this is a textbook for GIS classes in urban planning plus a workbook for local governments. Planners, analysts, and other local government staff can get hands-on experience using data sources from a real city to: build a geodatabase from CAD files and tabular data; define coordinate systems; construct table joins; create and workwith topologies; fix, update, and edit spatial data; perform attribute queries, field calculations, and much more. Working with ArcGIS 9 geoprocessing tools, you will perform spatial analysis to produce land-use reports, analyze residential density, and find possible drug housesnear playgrounds." "After doing the exercises in ArcGIS and the Digital City: A Hands-on Approach for Local Government, you will understand the power and the problemsassociated with working with real data in a GIS, and you will be able to use ArcGIS Desktop to address issues crucial to cities and counties."--BOOK JACKET.
