Comment:
Without going into too many details, I'd expect you to be able to define
two [https://docs.djangoproject.com/en/2.0/ref/models/expressions
/#writing-your-own-query-expressions user functions] (something like
`LLToBox()` taking two arguments and `LLToEarthBox()` taking three) and
use the builtin `contains` comparison, or, if this doesn't work, define
your own [https://docs.djangoproject.com/en/2.0/ref/models/lookups/
comparison].
In general, please direct such questions to the available help channels. I
am closing this ticket as invalid, for more details see
TicketClosingReasons/UseSupportChannels.
