'The Google Earth', that was before Google Earth

For those of you don't know, there is a Netflix Mini-series about Terravision (called The Billion Dollar Code), the first 3D mapping software developed in 1993 by the German company ART+COM in Berlin as a "networked virtual representation of the earth based on satellite images, aerial shots, altitude data and architectural data". The series talks about how Google stole their project and got famous with the stolen Terravision, named 'Google Earth'.
