Map Layers

Overview

These "open" map layers render information in near real-time from community curated Google Spreadsheets, or via syndicated data from the Greenville County, SC GIS.

You may request to contribute to layers by following the specific map page's "Contribute Link". When the spreadsheet opens tap the green "View Only" button, and then "Request edit access".

Each map has an example preview and, more importantly, a GeoJSON URL which allows for linking to these map layers within many mapping tool (Google Maps, Leaflet.js, etc) in real-time.
