Fetch Elevation Point Cloud to Generate 3d Surface #1

Open blairdgeo opened 9 years ago

blairdgeo commented 9 years ago

I want to be able to make a web service call to a commercial service: ESRI Image Surface, Mapbox Surface API and get back a point cloud JSON response based on my map envelope. With a point cloud response a 3.js surface can be generated on the fly.

NOTE: These type of requests can be expensive both from a payload and transaction cost.

Possible Esri Service to investigate: http://www.arcgis.com/home/item.html?id=58a541efc59545e6b7137f961d7de883 Keep in mind we need response as JSON points with elevation (XYZ).

@ajzeigert threw down a good option....http://ned.usgs.gov/epqs/ Maybe we could create a tile size and fetch a point across each centroid.
