I downloaded the existing data, then loaded the CANVEC data, then uploaded the
result.  I now plan to fix it as soon as I find out the best way to go about it.

I don't have anything else that I'm planning to import at this time, but I'll
certainly try to do that the next time, if there is one.  Actually, I thought
that's what I did this time, but apparently not, somehow.

It occurs to me that I may have been doing this wrong, and if so now would be
the time to find out about it.

The Coop grocery store, for example, is laid out as a building on a large lot,
the unoccupied portion  of which is customer parking.  I outlined the store,
marked that as the Coop, then outlined the parking lot and marked that as
parking.   However, I'm wondering if I should have outlined the whole thing and
marked that as the Coop, then made two smaller outlines within that for the
building and the parking lot.  If so, should I also name the smaller outlines
as Coop, or is naming the large outline around everything sufficient?
