Warning

This section is outdated and currently being revised.

The spectral profile panel allows you to collect, visualize, label and export spectral profiles.

  • Use the pickrasterspectrum Select a spectrum from a map button to extract and visualize a pixels profile (by clicking on a pixel on the map).

  • You can add a selected spectrum to your spectral library by clicking on profile2speclib.

  • The gathered spectra are listed in the table on the right. For every spectrum additional metadata will be stored, e.g. the date, day of year and sensor.

  • When the profile2speclib_auto button is activated, the profile will be directly added to the library after clicking on a pixel.

  • Change the display style (color, shape, linetype) in the Spectral Library Properties, which can be accessed via the action button in the lower right.

Note

The spectral library table behaves quite similar to the attribute table you know from QGIS:

  • You can edit the content by entering the editing mode mActionToggleEditing

  • You can add further information by adding fields via the mActionNewAttribute button (e.g. different class labels). Remove them with mActionDeleteAttribute, accordingly.

  • Double-click into a desired field to change its content

  • Remove spectra by selecting the desired row(s) in the table and click mActionDeleteSelected
