Abstract
Los Angeles: How a City Is Using Digital Orthophotography to Expand Its GIS DatabaseTrack: Database Design, Automation, and Management
Author(s): Joseph Bartorelli
Georeferenced orthophotos form the foundation of any city's GIS database. Large metropolitan city governments face special challenges to keep their mapping programs up-to-date, due to their sheer mass. The City of Los Angeles has contracted HJW Geospatial, Inc., an aerial photography and digital mapping firm, to provide digital orthophotographic imagery of the entire 550-square-mile city. The orthophotos will provide the base map for the massive City wide GIS database and will be available to numerous agencies within the City. This presentation will focus on the process of initiating, implementing, and successfully completing a large metropolitan citywide digital orthophoto project. The value of using Esri software for quality control throughout the project will be discussed. Lastly, specific applications and benefits of orthophotography for a multiagency organization will be illustrated.
