DESCRIPTION:GeoJSON is one of the most common geospatial data formats. In s
 imple terms\, it is an extension of JSON with geometry property. It is tex
 t-based and designed with human readability in mind. For the sake of being
  eye-convenient\, there is a performance trade-off when the browser render
 s it. GeoJSON consists of features containing redundant property keys\, ca
 using the size to be bloated as the feature size goes up. Commonly\, drawi
 ng GeoJSON with the size of tens megabytes would be slow. Showing a hundre
 d megabytes of GeoJSON data on the browser would most likely crash the bro
 wser.\n \nWhen we are in complete control of the system: back end\, front 
 end\, or anything in between\, we could probably change the source format 
 to something more efficient like Vector Tiles. But what if we can only twe
 ak the front end?\n \nWhen we can only tweak the front end\, geojson-vt co
 mes to the rescue. Initially designed for Mapbox\, we can pair it with Ope
 nLayers to render GeoJSON on the fly as Vector Tiles. We will compare the 
 performance between direct GeoJSON rendering versus geojson-vt for differe
 nt types of GeoJSON. The usage is straightforward\, making it a pretty eas
 y solution to improve our map’s performance. On top of that\, we could s
 till use Vector-specific Open Layers function like getFeatures when needed
 .
