Someone yesterday commented that Google earth showed a 10’ variance in elevation from one point on the “court” to another.

See my post 766. The elevation data may be older than the photographic pixels.

It may also be that the wind has lifted the tarp.

not an expert on how google earth measures but my thought is unless the satellite is directly perpendicular over the two points your are measuring too the distances would vary slightly just based on geometry and the distance would be different based on the angle in the sky the satellite was off the perpendicular..
