Multispectral Spectral 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.

The postcard is an item of ephemera donated to the UCLDH Digitisation Suite by Prof Melissa Terras, for teaching and training purposes in 2015.

This folder contains:

• Images captured using a PhaseOne XF Multispectral Camera System. 
  • Image filenames are arranged as postacards_postcardmsi-Postcard- (Wavelength No.)(Filter)_*sequence order number*_R.tif where wavelength number is the nominal central illumination wavelength in nm (365, 385, 410, 420, 450, 480, 510, 550, 600, 630, 640, 660, 740, 850, 940), Filter is the colour of the long-pass filter (N - no filter, I - Infrared filter, G - Green filter, R - Red filter) and sequence order number is a count from 0001 denoting the order in which the image was acquired)
  • Complementary flats for each of the object images, used typically to process even illumination distribution, captured of white, flat, smooth, non-chemically processed imaging standard flat paper with the same naming convention as above. 
• postcard_postcardmsi-Postcard.json - Metadata read out collected from MS camera system
• Truecolour RGB reference image
