I've a scenario that I need to display many lines on the map (for instance all road links of Manchester in UK). I am using Leaflet as map plugin. I use geoJSON as source of data, when I try to load more than 1000 features the map and browser become unresponsive.
What do you propose to improve performance when number of features to be drawn is larger than 1000 (even more..)?
I was thinking of a way to just display only roads which are in the shown map extent. But still if user zooms out number of features will be exceeded.
