LabVIEW does not provide native support/APIs for using offline/online maps. Most of the map support in LabVIEW is through independent Third Party Add-Ons such as Google Maps API
and INSol Offline Maps API
. These Add-Ons are not supported or maintained by NI & you need to reach out to these Third Party Add-On providers for your specific requirement or query. In some cases, they might do custom development as well based on your requirements.
You can reach out to the above providers to enquire about your specific use case at below contacts -
