Marker shifts position (relative to image) when switching from overhead to 45 degree view. Fix?
Fraggle
Google Javascript Maps API 3.5
Basic issue is that if you have a marker that is over a fixed landmark like a fire hydrant in the overhead view, then you switch to 45 degree view, the marker no longer shows on top of the hydrant. And vice versa (position the marker in 45 degree view then switch to overhead).
To reproduce:
-Create a basic Google Maps web page with a draggable marker. With initial marker/map position over an area with 45 degree imagery available: (try: 33.501472920248354, -82.01948559679795). I'm not certain it shows this problem for all areas so try that point to start.
-Make sure you are zoomed in near the max and in Satellite view
-Turn off 45 degree imagery
-Position marker over fixed point (corner of sidewalk, house chimney, etc)
-change to 45 degree view.
-Note that marker position is shifted
-Try rotating the 45 degree and see how marker shifts relative to original point on image.
-Switch back to overhead and marker is in original spot.
Why its a problem: Don't know what to trust. What view shows the accurate position for that marker? Can't create web pages that allow people to position markers in one view and see them in another. Major inconsistencies.

current API, but without handling z value, 45 images will likely have
distortion of the location, that's just the nature of the problem
until the API start to request elevation values for the marker and
process it accordingly.

Any thoughts on it, work around, etc?
