Hi Alan,

The aerials are currently for jurisdictional use only. There does seem to be
a push for making data public - maybe someday they will be available. I
don't know.

We are using the aerials to determine the accuracy of OSM and RLIS, so we
just use it as a background layer. In some cases, OSM is more accurate than
RLIS. The aerials help us send feedback to RLIS and determine where a change
in OSM is justified.
