Geo type in geo object 2.0

Background/Problem Description:
Publishers might not pass along lat/lng, and DSP wants to target at hyperlocal(true lat/lng) instead of reversed lookup by zip, or city.

Proposed Solution:
optional field "type" that specify what type of location geo object truly comes from

This makes sense. Whilst most SSP's will not pass along lat long if there is none available, it is possible that somebody out there will want to "help" a DSP and send back lat long reverse looked up from IP. So a type field would be perfect - "gps" or "lookup" or something like that.

I think values for a geo type field could be:

• gps: actual device lat/lng determined by a mobile device's GPS
• cell tower
• zip: zip code of the device location. We see this come through often on our network.
• city: city level location. we don't see this very often and maybe it is not necessary.
• dma
• IP
• area code: the centroid of the phone number area code. Obviously, this can be quite large.

the key thing here is geo type - i.e. how was it obtained

zip, city, etc is often also looked up from IP, so type is crucial, as if it is - it will often not be very accurate

That is correct, type is crucial. There are use cases where the type can be city or zip, i.e., the lat/lng values were derived from a zip code or city/state values. E.g., using a weather application I can specify my location by typing city/state or zip code values. Those values are then used to make an ad request.
