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

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

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

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?

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
