由 不想你离开。 提交于 2019-12-12 00:24:40
问题 I´m new working on Maps API V3, but I can´t find a way to put multiple polylines inside one array, so I can make them show/hide with a button (all at once).

Create Elevation profile from polyline coordinate array

由 心已入冬 提交于 2019-12-11 01:41:34
问题 I have created a polyline using a coordinate array with code adapted from https://google-developers.appspot.com/maps/documentation/javascript/examples/polyline-simple Although the first (and probably worst) method to make the line was just a huge list of lat/lng points. Still learning the programming tricks, I apologize. Im a geographer not a programmer! I want to get the elevation from that line and create an elevation profile graph. Im new to JS and not sure how to debug whats not working.

Polyline not visible Android Maps Api v2

由 强颜欢笑 提交于 2019-12-08 09:33:34
问题 I am a little bit confused since everything seems to be alright with the code. The problem is that the polyline won't show up on the map. Here is the function that I call to place polyline everytime I receive a location (I added markers in a similar way and they work great) private void addPolylineLocationOnMap(LatLng newLoc) { PolylineOptions poly = new PolylineOptions() .add(newLoc) .color(Color.BLUE) .width(5) .visible(true) .zIndex(30); googleMap.addPolyline(poly); } 回答1: A Polyline needs

How to ensure that follow specific google map road while using Google Map API?

由 感情迁移 提交于 2019-12-08 05:39:29
I am trying to draw a path on roads and follow some given points.I am using Google Directions API to follow the roads.I put some markers on roads and link these points with polylines.I need to follow the red line but it follows and draws blue lines.How can I ensure this? Verify if it is a road at all by zooming in. Also Make sure that u can tread in that direction in the road.Sometimes roads are one way, So google automatically chalks out an alternative path. Hope this helps. 来源： https://stackoverflow.com/questions/26161459/how-to-ensure-that-follow-specific-google-map-road-while-using-google

Draw google polyline with line width set in meters

由 天大地大妈咪最大 提交于 2019-12-07 18:14:35
问题 I noticed that when you draw a polyline in google maps you set it's width in pixels (strokewidth). Is there a way I could set that in metres instead? 回答1: Unfortunately, I don't know any easy way to do this. The API does not appear to have documentation on this and I assume this feature is unsupported. One problem is that the pixels represent a different number of meters at different zoom levels within the API. So it would be a dynamic quantity if the zoom levels are changed. One option might
