Feature Chula Vista's GIS team built a Web site based on ArcGIS Server using ArcGIS JavaScript Extension to the Google API and the ArcGIS API for JavaScript. Each property is mapped with a Google "balloon" and color coded based on the inspection status. to the Google API and the ArcGIS API for JavaScript, the GIS team created the Web site and embedded the digital map into the HTML document. "With a basic understanding of HTML and JavaScript, we were able to use some of the sample scripts available on the Esri site and get the initial site up and running in a few days," said Blackwelder. With its debut in November 2008, the new mapping site is used in the field on a daily basis by code enforcement staff. Previously, staff had no way of identifying clusters of foreclosure properties. Now, each property is mapped with a standard Google "balloon" and color coded based on the inspection status. Users can click on the balloon to retrieve the case number, status, and program date for the selected property. Code enforcement officers can open the mapping site prior to field visits, see clusters of properties to inspect, and plan their day accordingly. Using a pull-down list, they can display all RAP data or view just single-family www.esri.com or condominium locations. Another pulldown list allows users to map all properties or just properties assigned to a specific code enforcement officer. As officers in the field collect data about a foreclosed property, the data is fed directly to the Permits-Plus server. This allows office staff and field inspectors with wireless capabilities to immediately view updates to inspection status on the Web page. Since the initial development of the mapping program, management in the Code Enforcement Division has noticed a significant increase in productivity. Many code enforcement officers report that the productivity increase is a result of having more time to process cases rather than spending time determining property locations or printing driving directions between locations. Additional tools have also been added based on end-user comments and feedback. One link, added to each property, provides driving directions from city offices to the site. Another link brings up Google street-level images for the selected property. Users can use the mapping site to zoom to an area and export all data within the map extent as a Microsoft Excel file. With the success of the RAP viewer, Chula Vista is considering other ways to take advantage of ArcGIS Server to create more online maps that would link business data and map services in a simple Web site. The Public Works Department would like to map city assets along with related information from the city's GBA Master Series software [a work management system]. Using ArcGIS Server, they could build a project-specific mapping site and allow staff to view recent fieldwork related to these assets.

To learn about creating these types of applications, two instructorled courses, Introduction to ArcGIS Server and Building Web Maps Using the ArcGIS API for JavaScript, and a free Web training seminar, Building Mashups Using the ArcGIS API for JavaScript, are offered by Esri.
