Is there any tool for color bar in seadas 8.0 beta version like in earlier versions of seadas 7.5.2. I want to label few values between minimum to maximum in color palette not all. Selecting one by one and removing many values in new color palette slider is very time consuming if I want to do it for multiple images.

We are currently developing the color bar tool for SeaDAS 8.x. It will be similar to the color bar tool in SeaDAS 7.x, but a bit better. In the meantime, you may wish to use SeaDAS 7.5.3 for exporting your color bar.

When making many similar images with color bars, coastline overlays, grids, annotations, etc., 3rd party command-line batch-oriented tools are often more appropriate than SeaDAS, such as:

• [GMT](https://www.generic-mapping-tools.org/)

• IDL or [GNU Data Language](https://en.wikipedia.org/wiki/GNU_Data_Language)

• [NCAR Command Language](http://dx.doi.org/10.5065/D6WD3XH5)
  [main site](http://www.ncl.ucar.edu)

• Python (e.g., using basemap and matplotlib)

• GIS Software (QGIS, ArcGIS, etc)

I have the basic knowledge of these tools. Will try to explore these tools more for ocean color applications, if possible

It doesn't make sense for SeaDAS developers to put a lot of effort into duplicating capabilities already present in general purpose tools, and those tools have much larger user bases so more avenues to get support if there is an issue.

There are examples using many of the mentioned tools in the [HDF Group Zoo](https://hdfeos.org/zoo/index_openOBPG_Examples.php)

I often use one tool to make a base map overly with coastlines, grids, etc. as a vector format file (e.g., PDF) and a different tool to make the false color images. Some care is needed to ensure the mapping is consistent between the different apps, but once you have the details worked out you can process 100's of images with batch scripts, and with small changes produce browse or web quality imagery as well as publication quality. For publications you can overly a vector base map on a series images using LaTeX or other publishing apps.
