Hyperspectral Imaging dataset for use in Heritage Science

The following data sets were collected to support the potential uses of opensource data in the context of digital humanities and heritage sciences.  

This proposed experiment is conducted by the UCL Institute for Sustainable Heritage in collaboration with the Centre for Digital Humanities. Imaging methods including Photography, Multispectral Imaging, Hyperspectral Imaging and Xray Fluorescence Mapping have been collected along with the complete readout metadata of the instrumentation.  

We hope that you find the data helpful, and we welcome you to use the data in any way you wish, for all and any analysis development purposes. For us to build upon this research, we ask that in return you would be willing to share in some regard your experiences in using open-source data, using our data, successes and issues.  

If you would be willing to engage with us in this endeavor, please feel free to contact us so that we may be able to follow up with you.

This folder contains:

Hyperspectral Image data collected using a ClydeHSI VNIR-HR+ Hyperspectral Imaging System.

Images captured : 477x484 pixel, 304 spectral band images, 4*4 pixel binning

• *.hdr - Header file read out from the ClydeHSI systems instructions for reading the subsequent .raw spectral database. 
• *.raw - Hyperspectral image data cube information. Combination with hdr file creates a ENVI file format, this can be read into a variety of image analysis software packages. 
• postcardhsi.ini - Metadata collected and read out from ClydeHSI system.
• Dark/White.corr - Correction files taken from camera for processing and minimalising system noise and illumination variences.
• *_refl.* - Pre - Corrected hyperspectral image data, using provided ClydeHSI software.
• Truecolour RGB reference image 

Each raw and header file set makes-up a single data set in ENVI file format. 

ENVI reading support exists in Python, R, Matlab, and other common image analysis packages.
