I'm using Kendu UI Map object; I'm finding that larger GeoJSON data sets (even simplified ones using mapshaper.org) take a bit of time to load each time I zoom, for each zoom level. I'm working with GeoJSON data, specifically the US Counties data. I've simplified it a bit in an attempt to shrink the filesize, but simplifying it any more distorts the county lines too much.
Is there any way to dynamically load only the counties in view? I'm basically loading the counties on one layer. There are a couple other layers, but I've turned them off. I've not separated the counties by state and tried turning on and off the states that are in view, nor do I know if determining the view port vs. map items to load is trivial or not. It would take a bit of time to extract all the states or convert them from the stl file to GeoJSON.
Any ideas? Am I going about this all wrong?
