Can you create a GEOIP database of your own companies RFC1918 IP’s?

I am wondering is there a way to generate your own GeoIP database for your companies own RFC1918 IP's? What I am trying to do is take our office locations city, Office IP subent/s, and Lat/Lon and make my own database so that I can see the interconnectivity of my own companies commuications.

This way I can go to the Endpoints Map and see the relation quicker.

Thank you in advance.
