CorStruth - Automated Analysis of HyLogger Data from the NVCL

 
New in December 2017
82 New NT Holes - New Format for Google Maps Display - Links to Images of Core

Progress continues on improving jCLST.  These changes are guided by making detailed comparisons with results from expert interpreters. Of course it is not perfect and more work remains to be done. The main challenge for the future is (still!) to improve performance when the SWIR data is aspectral or almost aspectral because errors in the SWIR interpretation are compounded when propagated into the TIR interpretation. 

The current CorStruth products are:
Interpretations (like the one opposite) suitable for A4 presentation with variable bin sizes.
Browser-based scrollable images with a standard bin size of 0.25 m. (e.g. here)
Downloadable CSV files of TSA+ and jCLST interpretations binned at 1 m intervals.
Mineral Occurrence Maps (MOMA's) of various minerals identified with the NVCL data

There are three ways to access the interpretation images. (See here for more details)

CorStruth's purpose is to provide automatic interpretations of the HyLogging data from every HyLogger-3 datset acquired as part of the AuScope National Virtual Core Library (NVCL) program. The results are free for you to copy but remember that they have been produced by automatic algorithms which will make mistakes. In this regard make sure you read the notes under Cautions.

The NVCL program is a team effort and thanks are due to everyone involved  - both individuals and organizations. And here most of them are at the 2017 NVCL Workshop in Sydney.
