ABSTRACT

The Stone has developed a Web Mapping Tool that uses California Pesticide Use Reporting database data maintained by the California Department of Pesticide regulation. This rich database application contains 11 years of pesticide use (2000-2010) data on 1,278 chemicals on 280 crop uses for every section (640 acres) where a chemical is used. The data is collected by counties and then aggregated by the state. To help automate and facilitate its use, Stone created a FLEX-based ArcGIS Server application to present and visualize the data. We will demonstrate the application’s functionality during this session. Key elements of the application visual animation of pesticide use over time using year slider; using the dynamic legend, click on section for bar chart of 11 year history; optimized responsiveness; options for filter (chemical, units, sites, and year). The tool allows the user to get a good understanding of the historic use and amount and their locations. This tool allows easy understanding of where there may be environmental issues related to chemical use.
