We are developing a commercial app for iOS and Android. The app will display development plans(architectural drawings) in a real world 3D environment. The app will work by creating a Unity3D mesh, applies a google earth image as the texture then draws out 3d lines(architectural drawings) over the Unity Mesh.

Question: We are unsure if this is allowed under Google's terms and agreements? See quoted text below.

In the bold text below its a little vague whether what we are doing(explained above) is violating their terms and agreements. What do you think? Does anyone know how we contact google to ask them?

You may not mass download or use bulk feeds of any Content, including but not limited to extracting numerical latitude or longitude coordinates, geocoding, text-based directions, imagery, visible map data, or Places data (including business listings) for use in other applications. You also may not trace Google Maps or Earth as the basis for tracing your own maps or geographic materials. For full details, please read section 10.3.1 of the Maps/Earth API Terms of Service.

Does anyone have any advice/experience dealing with this stuff?
