[GRASS-dev] dead links in references for GRASS LiDAR processing

The first two of the links for references on the GRASS LiDAR tools are dead links. Can the relevant documents be found and put onto the GRASS server where they can be archived and maintained? The third link is still live, but slow. Perhaps it would be good to also archive that PDF where it is more easily accessible.

It depends - if they have the proper license.

so nothing to do.

I have update the one link and also the titles in the Wiki page.

Hopefully the original authors can respond to this.

Again, the original authors need to respond here

Good. But how stable is the link? I worry about references that are not at stable locales. If the license permits, it seems better to put it on our own site so it doesn’t disappear, don’t you think?

Thanks. I guess we need to hear back from the authors.
