In July 2018 Google Inc. changed their licensing policy for the Google Maps platform. In the attached document DataKustik explain what this means for CadnaA users and how to obtain a Google Maps API key from Google to allow you to download bitmap tiles. Download user document here.
Google Earth 7 does not work with CadnaA, as Google do not offer an API for this version to link to external software. Version 6 of Google Earth (which did work) is being removed by Google as of 31st October 2018. All users will need to use Google maps in the future.
CadnaA 2018: use Google Maps and API key as described
CadnaA 2019: use WMS or Google Maps and API key if there are no tiles left
CadnaA 2017 or earlier: unfortunately no satellite images available anymore via Google. To do so you would need to upgrade your CadnaA version.
If you have maintenance agreement we recommend you update your software now to version 2019. The attached will show you how to link to google maps.
As an alternative to using Google Earth we have put together a tutorial on how to use openstreetmaps which can be seen here.
