I was reading Extracting tree crown areas from remote sensing data (visual images and LiDAR) with interest and saw a comment made by @Aaron about links to documents breaking and how answers should be better than a 1 liner.

This got me thinking after I had followed the link to the paper. Just about any decent Journal utilises the DOI. So my suggestion and I have no idea how difficult it would be to implement in GIS StackExchange is to have another button or augment the current link button to allow a user to specifically enter the DOI number. In theory @Aarons arguments should go away as the DOI is unique and persists.


Just an idea?

  • That is a good idea. Although providing a full reference to the literature would also work.

    unfortunately it does not help when links break (as many websites get revamped way to too often).

    @Mapperz, so you have had a doi link fail on you?

    doi is ok but the link through is unavailable dx.doi.org/10.1007/springerreference_62186

  • Interesting I have always understood the doi was a solution to all these problems, clearly not!

  • @Mapperz According to the authorities, that's not a correct DOI. Where did it come from?

  • This would need to be implemented SE network-wide rather than locally at GIS SE so I have set it to status-deferred i.e. deferred to Meta Stack Exchange.

This was asked long ago but has not been answered.

To implement this would need to be a SE network-wide enhancement and much broader than the slight site customization that we can achieve internal to GIS SE.

Consequently, I recommend that you research it at Meta Stack Exchange instead of here. I just did and found the Q&A to Add explicit support for citing scientific literature that looks hopeful.
