A projection would be an application of the data, not a modification of this data. And the EPSG data aren't the holy grail either, there is more precise data available (non-free). Consider you being a company or some entity that wants to refine the data for a certain part of the world, you wouldn't have the right to do so. I can think of tons of applications that would require changing/refining the data. Even for changing the format and base coordination system to adapt to computations for a given problem, which semantically would not modify the data, but technically it does and could be violating the license again (I haven't read the license, just infering from what this thread is discussing). > But than, e.g if i invent one wich i think fit perfect for some land i will look > forward anyway for someone's help to certificate at all it, since i will not be able > to claim it is functional and better and more precise than i dont know wich one > particulary. And if its about certificate it probably i go EPSG to help me out. Or maybe a competing entity that will have emerged.
