Building on the success of the AHRC-funded AI for DIGILAB project, the ISAAC Research Centre is excited to announce the launch of a new facility: the ISAAC DigiLab. This is a standalone facility, offered free of charge to non-profit organisations engaged in heritage science research.
The ISAAC DigiLab will provide spectral imaging data processing such as clustering for large data sets, using an automated methodology which was developed during our large scale survey of wall paintings at the Mogoa Caves UNESCO site and other Cultural Heritage projects. Our user-friendly GUISI visualisation tool will be provided to the user for viewing the results.
The ISAAC DigiLab can be used in conjunction with the ISAAC mobile lab facilities for data capture, or for analysis of data which are captured "in-house" by institutions which have their own analysis equipment.

Types of spectral imaging data for processing
“Spectral Imaging” is usually interpreted as reflectance imaging at continuous spectral bands in the UV, visible and near IR wavelength range. Here, we are taking a broader definition of spectral imaging to mean any dataset that has 2D spatial axes, plus a third spectral dimension (e.g. energy for XRF image cubes, wavenumbers for FTIR image cubes and wavelength for VIS/NIR reflectance spectral imaging). At present, therefore, we can provide data processing for the following techniques:
Reflectance Spectral Imaging
Reflectance Spectral Imaging allows a meaningful reflectance spectrum to be extracted per pixel
Multispectral/ Multiband Imaging
Multiband imaging is distinct from Reflectance Spectral Imaging in that it is a loose combination of broadband images that can be discontinuous or even from different imaging modality (eg. UV fluorescence, Red, Green, Blue, NIR)
XRF (macro scanning & micro scanning)
X-ray Fluorescence scanning gives an XRF spectrum per pixel
How to Apply
If you would like to use the ISAAC DigiLab for data processing, please apply directly to the ISAAC team by filling in the DigiLab proposal form. Please also download and read the Terms & Conditions of using the ISAAC DigiLab, and keep a copy for your records. Once your project has been approved, an email will be sent detailing the next steps. We look forward to working with you!
