Merging multiple encoded polylines into one encoded polyline

Question

I\'m trying to merge a new encoded polyline with an existing polyline without decoding and reencoding the whole polyline. The new encoded polyline will be uploaded to a (lin

Answer 1

Decoding is performed by the browser. You can send individual line segments for the browser to decode & concatenate. Polylines accept a single "path" property. Polygons accept multiple "path" properties in an array of paths. The only difference between a polyline & a polygon is the absence or presence of a "fill" color & "fill" opacity. If you declare your polyline to be a polygon without "fill" properties, you will have built a multi-segment line from individual pieces.

P.S. - the "stackoverflow" editor really sucks.
