必应地图与Google地图->标记在不同的地方 [英] Bing Maps vs Google Maps -> markers are in different places
问题描述
我已经制作了2张地图，一张是Bing Maps，另一张是Google Maps. 他们俩都从同一个数据文件中拉出一堆图钉. 但是，必应地图上的图钉看起来像是向北偏移太远，因此不在正确的位置.
I've made 2 maps, one with Bing Maps and one with Google Maps. They both pull from the same data file to put a bunch of pins on the map. However the pins on the Bing map look like they are offset too far north and so not in the right place.

推荐答案
The problem is with the icon you're using - the PNG file at http://upstairsweb.com/examples/SmallRedMapPin.png itself is 16px x 18px is size, but the visible part of the pushpin is only drawn in the top left hand corner of the image. Bing Maps by default anchors a pushpin icon at the bottom centre of the map image, but because of the lop-sided transparent area that will make the icon appear to be too far up and to the left. I don't know how Google Maps anchors an icon when you haven't specified an explicit anchor point - perhaps it just hard codes an anchor that, by chance, happens to line up with your points.
无论哪种方式，我建议您首先修剪图像以摆脱外部多余的透明区域，和/或在PushpinOptions中显式设置锚点，相对于其描述的点放置图标: http://msdn.microsoft.com/en-us/library/gg427629. aspx
Either way, I'd suggest you first trim your image to get rid of the extraneous transparent area around the outside and/or explicitly set the anchor point in the PushpinOptions at which the icon should be placed relative to the point it describes: http://msdn.microsoft.com/en-us/library/gg427629.aspx
