wmcenter(wm2,centerLatitude,centerLongitude,zoomLevel)

  • Particular maps may not support every available zoom level. If your map displays as completely white, try another zoom level. The map you are displaying may not support the zoom level you have currently selected. You can also select another base layer, which might support the specified zoom level.
