Hi, I'm designing an application where I have to load lots of polylines (trails). I designed a php server that returns the geometry only on the current map extent. The data is simplified per zoom level.
From zoom level 0 to 7, no big deal (loading only 'international' trails). At level 8, I start loading 'regional' trails, which can gives 1500-2000 polylines. Theses must be destroyed when the map zoom level changes (since the geometry is simplified/zoom level). Currently, I remove/destroy each polyline one by one because I can't "clearAllOverlays" since I have other overlays I want to always keep. So, I'm seeking knowledge/tip/example about how to implement what I'm trying to do more quickly. Could I use a GLayer and put all the Polylines there and flush them from there ? Is there a way to "clearAllOverlays" on one kind only (polyline) ? Even more, are 1500-2000 polylines too much ?
