Google Maps API 在距起点特定距离处沿路线显示图标 [英] Google Maps API Display icon along route at a specific distance from start

问题描述

I want to display virtual progress on a Google map. I want to display a map with a route and on that route I want to display an icon at some distance (that will be computed based on data) from the start. That distance could change from moment to moment or day to day depending on the data related to the progress along the virtual route. For instance on a route from LA to NY, one day I may want to display an icon at 772 miles from the start. The distance along the route can be in units or as a percentage. I have seen the google.maps.IconSequence object, but can't see how to use that with DirectionsService.

解决方案

A couple of "mile marker/kilometer marker" examples and an animated marker:

• every 2 km
• 2 markers at specific distances along a route
• An animated marker along a route
