Google Maps API sets the CSS Z-Index for each overlay according to the latitude. According to the doco "it computes a z index such that overlays further south are on top of overlays further north, thus creating the 3D appearance of marker overlays." Testing in FireFox 3, it appears like some of the map tiles have a higher z-index than the polylines, so they hide the polylines. This is more likely to happen in the north because polylines in the north have lower z-indices. Sometimes you can see the end of a very long vertical polyline, with the rest of it covered by a maptile. Not sure what you can try, perhaps loading the polylines in order with highest latitude first? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
