  1. Agricultural Pesticide Use Web Mapping ServiceTIAG Meeting #2 (7/25/07) Craig Wolff, M.S. Eng IT/GIS Manager CA Environmental Health Tracking Program Environmental Health Investigations Branch CA Department of Public Health

  2. Tracking Network Goal • Provide visualization and dissemination of environmental health data/indicators • Web mapping service accomplishes this goal • Large amounts of data in graphical form • Can be displayed in browser, desktop, reports • Can be overlaid with other EH data • Can be displayed at any portal w/ min hassle

  3. Pesticide WMS • Derived from Dept of Pesticide Regulation (DPR) “Pesticide Use Reports” • Millions of different “chloropleth” maps • Follows Open Geospatial Consortium Web Mapping Service (WMS) interface standard • Demo is one possible glimpse of “back-end” WMS; not all functions are demonstrated

  4. Pesticide WMS • WMS is for visualization and dissemination only, not for linkage (“spatial analysis”) with other geographic data • Pesticide WMS has been used extensively for identifying communities near high use for biomonitoring project

  5. Questions to TIAG • Would you (agency, organization, etc.) or your constituents use this tool and data? If so, how? • With respect to visualization/dissemination, what should be added or changed? • Would it be useful to display this tool/data on other websites? • Would it be useful to do something similar with other EH data? Which data?

  6. Demonstration

  7. Other Possibilities • On the demo page (less work): • Maps of one or more counties • Pesticides and crops beyond Top 20 Lists • Additional color schemes • More detail about pest applications on marker popups • Zoom to address, zip, city • From the raw data in the maps (more work): • Greater temporal resolution than annual summary • Application method (air, ground) • User-specified categories, cut-points, color-schemes

  8. Questions to TIAG • Would you (agency, organization, etc.) or your constituents use this tool and data? If so, how? • With respect to visualization/dissemination (not linkage), what should be added or changed? • Would it be useful to display this tool/data on other websites? • Would it be useful to do something similar with other EH data? Which data?
