Los Angeles County Automated GIS Election Mapping System
The County of Los Angeles, with a population of over 8.9 million, comprises an area of 4,083 square miles and has approximately 3,800,000 registered voters. The County also has approximately 6,300 established precincts and 11,000 subprecincts. The average number of voting precincts and polling places for its major elections is 5,600 and approximately 29,000 precinct officers. The Registrar-Recorder/County Clerk is responsible for maintaining the 600 districts of fifty different types including seventeen U.S. Congressional districts, fourteen State Senate and twenty-five State Assembly districts, five Supervisorial districts, eighty-eight incorporated cities, and about 100 school districts. Realizing that GIS was the best suited technology to maintain this information, the County is shifting its future processing to a GIS environment. This paper will discuss the development of the Map Creation System Interface (MCSI), an application to automate the conversion/production of the 1,600+ precinct maps. The
map elements include street centerline, precinct and district boundaries with special symbology and annotation, a customized legend enumerating major districts, and other features. A user-friendly interface was developed using ArcTools and AML, so that a nontechnical staff can create maps automatically without GIS training. Innovative use of dynamic segmentation for text, marker and route shield placement is included in the MCSI. The paper will describe the MCSI development and functionality and discuss potential future applications. Software: The ArcInfo-based application was developed using ArcTools and ARCMicro Language (AML) and runs on an IBM RISC/6000.
