Just wanna get some advice on the issue of copyright for maps...
I need a map for directing visitors to a venue, and I know that all maps are protected by copyrights. So obviously being unable to use any existing maps, I created a map from scratch using Photoshop, based on an existing map that is published.
The entire Photoshop file was created from scratch, and I merely used the existing map to trace the lines, block numbers, street names etc. What I hope to find out are...
1) Is this a violation of copyright?
2) If there's a chance of them arguing that this is a copy of their map, how far should I modify it that they cannot sue for infringement?
I understand that most of you guys are not lawyers, but I'm hoping someone knows the law pertaining to this aspect. Thanks in advance!
