Spectral 1.1.0 Working Release Notes

Developers should put working release notes here. Anything that needs to be communicated to users or developers concerning 1.1.0 should be listed here. This will eventually be turned into end-user release notes.

Spectral Processing Extension 1.1.0 has been released on August 11th, 2010.

This version of the Spectral Processing Extension only supports Opticks 4.4.X. If you want a version of Spectral Processing extension for use with Opticks 4.3.X, you must download an earlier version of this extension.

New Features

• All the plug-ins in the Spectral extension now copy the classification markings to new data sets. (EXTRAS-64)
• New features and user configuration settings for the Signature Window: (EXTRAS-73, EXTRAS-74)
  • New Spectral toolbar buttons:
    • Tool button that displays just the AOI average signature.
    • Tool button to toggle the new pin signature plotting to single plot mode.
  • New user options in the "Windows\Signature" section of the "Tools\Options..." dialog:
    • Set to use a fixed color or the AOI's display color for plotting AOI average signatures.
    • Set to use a fixed color or the AOI's display color for plotting AOI signatures.
    • Set the fixed color for plotting pixel signatures.
    • Set whether or not the plot will be rescaled when a signature is added.
    • Set whether or not all signatures will be displayed in a single plot.
  • New features:
    • Pin signature plotting - new mode that allows you to display signatures from multiple windows in the same plot. When this mode is active, all signature plotting will be restricted to the currently active plot in the "Custom Plots" plotset. The only restrictions are that signatures must contain wavelength information, and have the same type of units, e.g., Reflectance, Digital Number, etc. The default mode can be set in the "Tools\Options..." dialog - this sets the initial mode when Opticks starts. The mode can be changed by toggling the "Pin/Unpin the Signature Window" tool button in the Spectral toolbar.
    • Display the AOI average signature - click on the new "Display AOI Average Signature" tool button in the Spectral toolbar to add the average signature for the active AOI in the active window to the current plot for the active data set, i.e., the AOI average signature can be added to either the pixel signature plot or an AOI plot for a data set. If the pin signature window mode is active, the AOI average signature will be added to the currently active plot in the "Custom Plots" plotset.
    • Auto rescaling after adding a signature can be turned off. Use the new option to set the default behavior. Use the new context menu item "Rescale on addition" to change the current setting for a plot.
• Spectral now has an NDVI tool which calculates the NDVI of a dataset. The dataset must have associated wavelengths. Bands for the NDVI are chosen based on these wavelengths. The median band which falls in the appropriate red and NIR ranges is selected. The ranges are 630nm-690nm for red and 760nm-1000nm for NIR. (EXTRAS-63)
• The Wavelength Editor dialog and all Wavelength importers and exporters have been moved to the Opticks application and have been removed from the Spectral Processing extension. (EXTRAS-80)
• The Wavelengths class in SpectralUtilities has moved to the Opticks application and has been removed from the Spectral Processing extension. (EXTRAS-80)

Bug Fixes

• The Signature Importer now imports zero values and negative values as valid input. It no longer skips zero values as a bad band marker nor sets negative values to zero. This will affect very old signatures that use a zero value to indicate a bad band. The band will now be imported into the signature with a value of zero. (EXTRAS-59)

Supported Opticks Versions

• This extension is supported in any version of Opticks 4.4.X that is Opticks 4.4.0 or later.
