I have a geojson file around 250 mb showing polygons all across england, but it makes the application too slow loading this Native file in. I was wondering if there is any way to tile native geojson files? I have used tippecanoe to tile into an mbtile but unfortunately that was not compatible with cesium. If this is not possible is there any way to optimise large geojson files?
