Long story short- I imported Aerial Imagery of Philadelphia. I’m designing some things around traffic lanes, so I checked the measurement of the lanes. They are 10’, which is correct and matches on-the-ground measurements. However, when I measure from intersection to intersection, (i.e. from one street to another), the measurements are off pretty significantly (measured in Google maps as 370 feet, but measuring out in Sketchup at 240 feet).
I’m not sure how this could be and while I’m hesitant to rescale the model in just one direction, it seems like the correct move. But I don’t really understand why I should need to if the native Digital Globe is supposedly accurate.
Any thoughts on what to do to rectify this issue would be so appreciated!
