Map multiple data sets on the same map

[stuross]

I have 2 datasets:

Dataset 1 has a latitude and longitude value for every piece of equipment my company has working in remote locations.

Latitude

Longitude

EquipmentID

Dataset 2 has a latitiude and longitude value for every possible remote location that my company could be working, but does not currently have equipment.  These locations would identify potential customers.

Latitude

Longitude

LocationID

CompanyName

On the same map I want to plot the locations where I am currently working, and also plot the locations where potential customers could be so I can see them together.

How could I accomplish this?
