everyone. Recently, we have faced one problem about the speed of loading google map components on different broswer. Regarding to the function , we have added 120 polygons, 360 sector ( also polygon ) and several attributes which attach to components on the map. The verson of JS tool is Google Map Javascript V3.
Now, this module is running fast and smoothly on Chrome and Foxfire broswer. HOWEVER, terreble problem would occur on IE8 or IE9. The process about loading informations into map becomes very slow, also during the period of dragging or zooming the map, which can not be accepted by users.
So, is there any solution about acceleration in this situation ?
Thank you very much for any reply !
In my experience it’s just IE being IE.
I would suggest scaling down the number of polygons you need to show at one time by using the map bounds as the criteria to filter by. You’ll still end up running into issues if you let the users zoom out to show the whole map so you may want to limit zoom levels as well.
If you take all the points that make up your polygon and push(extend) them to a LatLngBounds you can grab the bounding box and check to see if the center of that bounding box is in the map’s current bounds.
