• Cloud-based 3D Web Client based on 3D City Database

    The 3D web client has been developed by Chair of Geoinformatics, Technische Universität München.
    The web client supports two 3D viewers: Cesium and Google Earth. For best viewing experience, please use Mozilla Firefox for Google Earth and Google Chrome for Cesium.
    The city model can be visualized without any credentials. However, to query or edit the attribute information of the buildings, please log in using a valid Google account.
    The Google account is only required for accessing the Google Spreadsheet used for building attributes; the application does not track, log or update any information of the account being used.
