The Planning Department in Community Development adds new streets on an ad hoc basis . The Emergency Services Department maintains the county ' s street centerline GIS layer. A general recommendation has been made to migrate all editing and maintenance of the street centerline layer to the recommended GIS Director (See Chapter 4 : Base Map Creation and Consideration ) . One of the primary goals of the County ' s GIS implementation is consolidation of all county data into one single repository database . It is recommended that the Supervisor of Elections Office work with the recommended GIS Director to ensure that the street centerline is centrally stored and maintained and that the street centerline is properly updated with the street index for the Supervisor of Elections . This workflow will allow Supervisor of Elections personnel to make sure that the street centerline is updated with the necessary streets and subsequently eliminate several hours of unnecessary field work to ensure street index and GIS integration . ` QX Case Study : Los Angeles County Registrar-Recorder/ County Clerk ( RR/CQ Los Angeles County is a geographically extensive area that covers approximately 4,080 square miles and includes a complex landscape of rivers , mountains , freeways , urban centers, suburban and rural areas, and a vast street network . The county is home to some 5 million registered voters , most of whom live in one of the county ' s 88 municipalities . To keep voter counts below state mandated limits per precinct, RR / CC divides the county into „ roughly 5 ,000 precincts . Nearly 500 ,000 street segments are needed to locate the voters on the Los Angeles County street network. Due to the sheer size and dynamic nature of the County, the volume of data edits required for routine precinct and district maintenance was significant . Moreover, since RR /CC ' s existing GIS system was not integrated with their existing Voter Information Management System ( VIMS) , these edits had to be entered into each system separately in order to keep the GIS and VIMS systems synchronized . To remedy this costly and time-consuming workflow, RR / CC contracted bd Spatial (formerly GIS/Trans , Ltd .) to develop a GIS system that would allow their Precincting Section to maintain the precinct and street segment data through a map-based interface without having to duplicate data entries a second time in VIMS . The resulting Single Point Data Entry „ (SPDE) system was built on a platform of ESRI and Microsoft software . The SPDE client application was developed with object-oriented techniques using ESRI ' s ArcGIS 8 desktop GIS software , ESRI ' s ArcObjects software component library, and Microsoft ' s Visual Basic 6 197 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment
