Dear ESRI team,
for teaching purposes, I'd like to learn more about the following and would much appreciate if you could provide me with your wisdom:
AGOL allows to upload .csv, zipped .shp, GeoJSON, KML and convert these into feature layer (hosted).
1) What is behind a feature layer (hosted)? Still the original file format? Or in every case converted into geojson or into any other interchangable format?
2) How are feature layer rendered in the browser? Through canvas? or WebGL? or...?
Kind regards
Stefan
