SHARE 2012 SpecTIR imagery
Direct directory of ENVI .hdr + .img reflectance cubes. Individual images range from about 951 MiB to 13 GiB.
Local scientific raster viewer
Open ENVI hyperspectral, GSF AFM, and FITS data in the browser.
PureJsImage keeps numeric samples separate from the RGB pixels used for display. Range selection, palettes, display transfers, and relief are explicit operations.
Local files stay localGSF, ENVI, and FITS files stay in this browser tab. Large ENVI and FITS files use bounded Blob reads.

Quantitative source values remain unchanged. Palette, stretch, scale, and relief affect only the streamed display pixels shown above.
The PNG is the current display rendering, not a converted scientific dataset.
Real public data
Download compatible scientific raster files
These university and U.S. government collections publish ENVI header + binary pairs and FITS image arrays. Large files should be downloaded before opening them above.
Official FITS sample files
The FITS Support Office publishes image, table, and conformance samples for testing FITS readers.

Open a FITS download: choose FITS image arrays, then select the downloaded file under FITS file. Open an ENVI download: unpack the archive, choose its .hdr file under ENVI header, choose the matching .img, .bin, or .dat file under Associated binary, then click Open paired files. A browser may save a header as .hdr.txt; the explorer accepts that filename too. GSF is commonly exported from AFM/SPM software rather than distributed by institutional archives.
Scientific raster formats
Numeric data and display pixels use separate steps
GSF, ENVI, and FITS remain scientific datasets rather than photographic codecs. Their numeric samples use the same dataset API as OME-TIFF planes.
