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.

Examples of Combining Multiple Map Layer

• VueJS + Leaflet Multi-layer Demo - via @oliviasculley's fork of @SpaceCowboy326's All Layers Demo Map
• Multiple Swamp Rabbit Trail layers in a single map via Andrew Bieber.

More technical details can be found in the Maps Documentation or by joining the HackGreenville Labs team in the #hg-labs channel of the HackGreenville Slack.

The map "Previews" seen under each layer listed below are rendered using Leaflet.js and custom code.
