Geological Survey Ireland: Hyperspectral

Geological Survey Ireland has a core scanning suite consisting of a Short-Wave Infra-red (SWIR) camera and a Medium-Wave Infra-red (MWIR) camera.

We have over 400km of drill core in our core store and are in the process of scanning all of it. We currently have ~7Tb of data.

A sample dataset consisting of 1 box of core is available to download from the Geological Survey Ireland website

The entire dataset is freely available please contact gsi.corestore[AT]gsi.ie to discuss.

For questions, issues, suggestions for improvement or to discuss collaboration, please contact Russell Rogers, c/o duty.geologist[AT]decc.gov.ie.

This repository will host notebooks using the sample dataset explaining some of the methods we have used in python to pre-process and process our image data.

1. Opening and Starting with Geological Survey Ireland Hyperpectral Data

2. Denoising Geological Survey Ireland Hyperspectral Data

3. Removing the core box from the image

4. Removing the continuum

5. Clustering

      This notebook uses the Minisom module, because it is a very lightweight implementation with minimal dependencies, but there are many other SOM implementations available in python.
