We are displaying the highest resolution imagery available from DG. 25cm resolution means that a single pixel in the imagery, covers approximately a 25cm x 25cm area.
The distortion is unfortunately a side effect of images take from satellites because a single image covers such a wide area. The priority from a provider like DG is typically focused on getting cloud-free views at a time of day that minimizes the length of shadows. Its not easy to cover the entire globe with those restrictions.
The other thing I’d like to mention is the core use case for Add location is - to approximately locate a building on a site. Trimble is not intending for the imagery to be used for geo-modeling or survey purposes. Users who require a high level of accuracy from their imagery should be sourcing their imagery from a reliable provider. I will see if I can get some recommendations and add those to the help center article.
One last thing, It appears that the deepest zoom level is broken. We’ll get that fixed asap.
