Nodes

  • Spectral Loader: load spectral file, output Spectral object and preview image
  • ENVI Loader: load imagery with associated ENVI header files and reading & writing spectral libraries with ENVI headers.

WIP

  • ~~plot node~~
  • ~~k-means node~~
  • ~~calculate nodes~~
  • pca node
  • save node
  • preprocess nodes
  • improve performance
