Highlights some new or newly identified known issues.

• General:
  • Time Series Tool
    • This tool is currently unavailable as of SeaDAS 10.0.0. This is due to the merge with SNAP 12.0, where this tool has compatibility issues. We do hope to restore this tool in a future SeaDAS release.
• Science Processors:
  • Specific to Mac OS: As of science processor OCSSW tag V2025.2 and later, SeaDAS must be launched from the command line in order to use the GUI for running the science processors. Launching SeaDAS via mouse-click on the application icon will likely cause the processor code to fail. This bug would apply to any SeaDAS version which tries to run V2025.2 or later.

Highlights some known issues and offers helpful hints for users encountering stumbling blocks:

• General
  • Open File/Product:
    • Seems to not open a file if the directory has 400+ files with some of the files not being netCDF files.
  • Layer Editor:
    • Can get out of sync with selected layer in Layer Manager (user workaround: the layer editor still works, but it is one-layer click event behind, and the user can activate the desired layer by clicking another layer in Layer Manager)
  • Band Selection:
    • Clicking a view window tab selects the view window as the active view, but does not auto-select the corresponding band as the active band. This can lead to confusion when run band-based tools. (user workaround: click the band in the File Manager will auto-select both the band and its view window and will avoid this issue).
  • System performance:
    • This is a concern with large files and the user should adjust the settings in the "Performance" preferences page which defaults VM to 8Gig. But 8Gig virtual memory may not ideally be enough for some files, so if the user has a computer with sufficient RAM then this VM can be increased if needed.
• GPT
  • gpt (graph processing tool) command line entries require full file path.
  • Coastline, Land and Water mask tool operator not available at gpt command line.
  • Bathymetry tool operator not available in gpt.

Known Issues

General

• Layer Editor can get out of sync with selected layer in Layer Manager (user workaround: the layer editor still works, but it is one-layer click event behind, and the user can activate the desired layer by clicking another layer in Layer Manager)
• Clicking a view window tab selects the view window as the active view, but does not auto-select the corresponding band as the active band. This can lead to confusion when run band-based tools. (user workaround: click the band in the File Manager will auto-select both the band and its view window and will avoid this issue).
• System performance is a concern with large files and the user should adjust the settings in the "Performance" preferences page which defaults VM to 8Gig. But 8Gig virtual memory may not ideally be enough for some files, so if the user has a computer with sufficient RAM then this VM can be increased if needed.

GPT

• gpt (graph processing tool) command line entries require full file path.
• Coastline, Land and Water mask tool operator not available at gpt command line.
• Bathymetry tool operator not available in gpt.

SeaDAS General Overview

SeaDAS 9.0.0 is an open-source comprehensive software package for the processing, display, analysis, and quality control of remote-sensing Earth data. SeaDAS serves as the official distribution point of the NASA OBPG Science Software. The science processing component of SeaDAS applies the OBPG algorithms to satellite data in order to characterize and calibrate the data and generate science quality OBPG products.

The SeaDAS 9 platform (an extension of the ESA SNAP platform) serves as an application platform to the NASA SeaDAS Toolbox and the ESA Optical Toolbox. The core elements of NASA SeaDAS science processing (both command line and GUI-based) are contained within the SeaDAS ToolBox. The NASA satellite mission data file readers and the ESA processors for the Sentinel-3 missions are contained within the Optical Toolbox.

SeaDAS Legacy Software Overview

• SeaDAS 8 series began an integration with the ESA SNAP software.
• SeaDAS 7 series contained the NASA OBPG processors and the GUI is a variant of the BEAM software. This series culminated in version 7.5.3 and will no longer be revised. It won't use the latest NASA processors.
• SeaDAS 6 series was based on IDL and is no longer supported.

SeaDAS Platform 8.4.0

General

• Supports Mac OS Ventura and the Mac M1/M2 chip.

Tools

• Angular View Tool (new tool):
  • This enables a plot of the band value across angular data of the band. The supported angular data is view angle, sensor zenith angle, sensor azimuth angle and scattering angle.
• Annotation Metadata Layer Tool (new tool):
  • This tool enables adding metadata and custom annotations to the scene image. This includes header, footer and margin annotations.
• Soft Button Tool (new tool):
  • This tool enables multiple layer tools to be assigned to a single button. For instance: with a single click the user can enable the Map Gridlines Layer, Color Bar Legend Layer, Annotation Metadata Layer, and turn on a list of their favorite masks. This tool also enables setting the scene image zoom.
• Color Bar Legend Tool (modification):
  • Colorbar legend can be configured by band-dependent configuration schemes.
  • Colorbar legend title supports file/band metadata replacement variables.
  • Colorbar legend title and units support text formatting such as superscript and subscript.
  • Colorbar legend units can display caret-notated text as actual superscripts
  • Colorbar legend placement on scene image can adapt to scene shape (vertical vs horizontal) based on a default scene image aspect ratio.
  • Colorbar legend placement default is now outside scene image.
  • Colorbar legend margins and spacing are now fully adjustable.
  • Fixed bug where an already added and customized colorbar legend sometimes would get reset to defaults
• Color Manipulation Tool (modification):
  • Color palette selector has been reorganized and grouped to make color palettes easier to find within the selector.
• Image Zoom (modification):
  • The default zoom when opening a band image will be slightly zoomed out to account for gridlines and color bar legend potentially being added. This default can be altered in the Preferences for Image View.
  • Zooming behavior regarding the mouse wheel interaction has been reversed from earlier SeaDAS versions. Now moving the mouse wheel forward results in zooming in. This default can be altered in the Preferences for Image View.
• Map Gridlines (Graticules) Tool (modification):
  • Changed label orientation default to be in line with the axis to better allow room for the color bar legend default of its being placed outside the scene image. This default can be set in the Preference for Map Gridlines.
• Layer Editor (modification):
  • Arrangement and alignment of data entry fields has been modified to improve usability.
• Vector Layer Visibility (modification):
  • When a user adds a Pin, Geometry, or Ground Control Point, the respective layer is automatically made visible so the user can see what they just added.
• No-Data Layer (modification):
  • Fixed issue where No-Data layer would sometimes change unexpectedly.
