Terrain Tiles on AWS from Mapzen

[PeterC]

"Terrain tiles provide open elevation data for the entire world in a raster tile format. By aggregating, standardizing, and tiling multiple source datasets into common web mapping and desktop GIS formats and dimensions, it’s much easier to process the data and build applications on top of it."

This may be a good way of enabling LIDAR type data to be used in our applications. It presumably ties in with Mapzen's Elevation service.
