hyperspectral scanning to support geological mapping in underground mines, we acquired hyperspectral data from three adjacent outcrops of Sn-W-Li greisen rocks in the visitor&rsquo;s mine of Zinnwald, Germany. The hyperspectral scans were pre-processed and then back-projected onto photogrammetric, three-dimensional digital outcrop models resulting in so-called &quot;hyperclouds&quot;. The here presented hyperclouds from the three outcrops (Z1, Z2, and Z3) contain the following attributes:</p> <p>ZX_Absorbance.ply<br> RGB colours: Mica/clay-zinnwaldite-topaz abundance based on absorbance (1 &ndash; hull-corrected reflectance) at 2200 nm (red), 2250 nm (green), and 2085 nm (blue)<br> Scalars: Absorbance at 2086.88 nm, 2160.69 nm, 2197.53 nm, 2209.8 nm, 2252.7 nm, and 2338.31 nm</p> <p>ZX_Iron.ply<br> RGB colours: Composite (Fe3+ Fe2+ FeOH) iron index (red: 600/570 nm, green:(920 nm + 1650 nm)/ (1035 nm 1230 nm), blue: (2230 nm 2290 nm)/(2245 nm + 2260 nm)<br> Scalars: Fe3+ = 600/570 nm, Fe2+ = (920 nm + 1650 nm)/ (1035 nm + 1230 nm), FeOH = (2230 nm + 2290 nm)/(2245 nm + 2260 nm)</p> <p>ZX_MNF.ply<br> RGB colours: Minimum noise fraction false colour (red: band 4, green: band 7, blue: band 5)<br> Scalars: Minimum noise fraction bands 4, 7, 5)</p> <p>ZX_RGB_mineralogy_Li.ply<br> RGB colours: True colour RGB from photogrammetric outcrop model<br> Scalars: Mineral abundances derived by combining sample mineralogy from quantitative XRD measurements and hyperspectral unmixing approaches: Quartz/Feldspar, Zinnwaldite, Muscovite/Illite, Kaolinite, Topaz, Lithium (by multiplying the zinnwaldite abundance by its average lithium content of 1.7%)</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dcat:distribution> <dcat:Distribution> <dct:rights> <dct:RightsStatement rdf:about="https://creativecommons.org/licenses/by/4.0/legalcode"> <rdfs:label>Creative Commons Attribution 4.0 International</rdfs:label> </dct:RightsStatement> </dct:rights> <dcat:accessURL rdf:resource="https://doi.org/10.14278/rodare.2078"/> </dcat:Distribution> </dcat:distribution> </rdf:Description> </rdf:RDF>
