Currently it is only possible to add a nadir logo by using iSTAR Pulsar+, downloading the data to an external drive and processing it offline - our Immersive Studio software has an option to select and apply a custom logo to the nadir of each image while processing.
Data processed online within our cloud-based VR.World platform automatically has the default NCTech logo applied to the nadir presently, however the functionality to select and apply a custom logo when using this method is planned.
