Requires

• Leaflet 1.x
• ArcGIS Online account (subscription)

Overview of steps:

• Create ArcGIS map with town labels (hide boundaries from view)
• Publish as Tile Layer on ArcGIS Online service (Trinity College subscription) http://www.arcgis.com/home/item.html?id=31c6f4f4360f4ab7b330b129086216de
• Use esri-leaflet to display town labels tile layer
• See Leaflet custom map panes tutorial to display layers at different z-levels http://leafletjs.com/examples/map-panes.html

Questions for MAGIC

• Can your team create a better ArcGIS tile layer of town names? In my version, some towns display multiple labels (see Torrington and Winchester)
• If yes, can MAGIC host this label-only tile layer on your server? I’m thinking it would be a better long-term public solution than Trinity’s ArcGIS Online account.

Alternatives considered

• Also tried free CartoDB light labels only layer, but insufficient detail
• Also tried creating labels-only tile layer in Mapbox Studio Classic, and MapBox Studio, but appears to require a subscription beyond free level; this testing example comes from http://googlemapsmania.blogspot.com/2016/02/switching-map-labels-in-leaflet.html

To Do

• Rebuild geojson data file for pop density
• change from click to hover, and add legend to display colors and hover data
• other minor changes
