Well that's not too difficult. Where did these people live traces, who did they trade with,... Take Saba (as that's the one I know best) we know with who they traded and where they went. We know that south arabians have been in Egypt (the ma'in left a lot of traces there and even a temple), we also even have an inscription at Delos. We can be quite sure they know about India due to their intense seatrade, we aso know they'd must at least have a general idea of Arabia (except for the driest desert places parts) due to the incense routes. A minaean inscription speak Sidon. The minaeans being the close neighbours and not the exclusive south arabian traders, and the sabaean information on it's own we could say they knew egypt, the levant, ethiopia and arabia very well. They'd have a decent amount of knowledge of the Indian coast and would at least know the bigger trading settlements from greece and turkey.
