Google is seeking the lifting of a temporary court order which has prevented it from updating its Street View service in Switzerland for more than a year.
Lawyers for the search giant will appear in court to challenge attempts by Switzerland's data protection commissioner to impose stricter privacy rules for the service.
Street View allows internet users to virtually tour locations on a map at ground level.
Google says the service is popular in Switzerland and comparable to similar offerings by rivals.
The data protection commissioner, Hanspeter Thuer, wants the Swiss Federal Administrative Court in Berne to require Google to guarantee that all faces and car registration plates are blurred.
He also wants sensitive locations and private gardens obscured.
