I'm trying to access the International Journal of Remote Sensing using Google Scholar
The link you gave http://www.tandfonline.com/doi/ref/10.1080/01431169308904419#tabModule is for the article with the title Characterizing tropical secondary forests using multi-temporal Landsat sensor imagery. It is from International Journal of Remote Sensing, Volume 14, Issue 16, 1993. We have access from 1997 to present only.
How do I know that? I have checked Stellenbosch's holdings on the library webpage under Search < E-journals. The steps on how to do this is in the box titled Use e-journals in the guide How do I find, access and use information effectively.
If we had access to the 1993 article you would have been able to open and download the full text article seemlessly via Google Scholar or via the Library's webpage. Only from offcampus you will be prompted to authenticate yourself with your SU network username and password.
For a 1993 article you need to use our Interlibrary Loans service.
I hope this information and hints is useful. Please contact us again if you have any further queries.
