Re: [Flightgear-devel] gpl scenery

Hi,

First of all: I am not a lawyer, but nevertheless I did counsel a patent lawyer in the past about GPL and its implications.

As Yves already wrote: The WMS data seems not to be a problem.

IMHO we may have a problem with the Navcanada data, since it contains the Notice "All rights reserved" (Emphasis by me on _All_).  Since we are using a derivative work, this is subject to a license conflict. Clause 7 of the GPL than applies: we are not allowed to distribute these data.

Greetings
Olaf Flebbe
