I have a series of letters, each with a recipient and sender address stored with Addressfield, with spatial data added Geocoder into lat/long and stored in a Geofield. I'm using IPGV&M, Views, and Leaflet to render these points - 1 letter to each row, with 2 points (sender / recipient). This is working fine.
I'd now like to add a linestring between those two points, but am at a loss for how to do that. Can Geofield store linestrings? Can I automatically generate a linestring and store that in a Geofield field based on the geo POINT values of the sender / recipient Geofields?
