[HOT] Mapping task for seismic risk assessment

In reviewing the existing building data, you are correct it is shifted.
However, the data does not seem to be very accurate.

In this situation, I'm wondering it makes more sense to double-check,
correct, and update that existing data, rather than try to bulk shift it
(which I've never done). But I'm open to suggestions on the best way

>From the imagery perspective, the Bing Imagery analyzer indicates the
imagery is from May 2013. The DigitalGlobe archive shows a lot of
collection in that area in May 2013, but one scene in particular (Catalog
ID: 1030010022C8C400) is quite good. If this is the scene in Bing, then I'm
inclined to think the imagery is spatially correct and serves as a good
base to map from.
