Is it possible to make bend with google maps polyline?

Will Google Earth ever make use of the technology in Google Maps where guess at the elevation of trees and buildings?

• I'm talking about the feature in the openGL google maps that allows you to spin the oblique images and it triangulates the height of trees, buildings and valleys. This would be very helpful in google maps to see at least roughly where trees are.

• Answer:

  I'm not really sure what you mean.  I just turned on their WebGL option and selected a supported area with trees to see what you mean (I chose Albany, NY).  Nothing is 3D here, at least in this area.  They just flew a plane in four different directions and used what looks to be some simple version of image based rendering to interpolate between the images.  What am I missing?  What region are you looking at? As for your question, you don't have to do image based triangulation to obtain building and tree heights.  Geospatial surveying firms will sell you digital surface models that do or do not include things like foliage.  This might be done with lidar instead imaging.  It depends on your application.
