should encoded polylines be usable as-is with Google static maps?

[Dylan Kuhn]

Since Google's encoding algorithm is used for polylines, I thought I might be able to transform a JSON response like

"map": {
    "id": "a32193479",
    "polyline": "kiteFpCBCD]",
    "summary_polyline": "{cteFjcaBkCx@gEz@R",
    "resource_state": 3
  }

into a Google static maps URL like this:

http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&path=weight:3%7Ccolor:red%7Cenc:{cteFjcaBkCx@gEz@R

Obviously it doesn't quite work. Before I delve into figuring out why, should it?

I guess the sample isn't a valid encoding. I shorted it so the docs would look good :)

http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&path=weight:3%7Ccolor:red%7Cenc:ka{eFnsdiV{l@g~@kHEdIlGxApEjIxD|DzFaB`DnVr\tD?

works fine from another activity.

You should check the polyline. I also use the static maps url from google to get an image and it works great:

My code:

public async void LoadMap()
        {
            String url = String.Format("http://maps.googleapis.com/maps/api/staticmap?sensor=false&maptype={0}&size=150x150&path=weight:3|color:red|enc:{1}",
                "terrain",
                ActivityEntry.Activity.Map.SummaryPolyline);

            Image image = await ImageLoader.LoadImage(new Uri(url));
            pictureMap.Image = image;
        }

I'm having a similar issue...   The g-maps api is returning a generic image.  This just started happening, was working fine before.  This is an example URL (using polyline from strava api):

http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&path=weight:3%7Ccolor:red%7Cenc:{ecxElqawNkNk@e@_D_FxDVyUtCiNXwn@qMyAcf@eh@qGiS{H_C{JiIUkb@cQm@}DwZ{RpD}AgNmZsBViQqA[ku@cE[v\q@ZgmAaNcPs[gE_Bp@wEoBqKgB|DRtDcHzK~B}[fAuDvGsDsD{G^iNtAoBcFuA@qI|B{@jNlFsGQhDtF{BhItAhBfGe@@yAgDp@^gC`Uw@vAwH~EsC{GsAeGmQvJzLtd@`DzLvNfBzEnNrDnGY|B~JdHr@~E{ArBdPlOvGhP{E|@zAq@|JbArDfElChGBrD`StFnMzDzZ|BxC|C~U`Nn@T~RbKbIlIrC~C`OdJfKsBfCnClDs@zBpCg@rVjVc@|AjAhAhFj@e@|N`EnCrBrP{CvP_@fVjF{Dp@~CjND

I copy pasted that link into my browser window got a nice map, see attached. Maybe you've been ratelimited?
