Draw polygon on a scatter plot in SeaDAS
I install SeaDAS in MX Linux 19.3.
Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
From the scatterplot help entry:
Select Mask 'scatter_plot_area'
Allows the user to create a mask from the scatter plot. After selecting the menu entry, an elliptical selection frame can be created by clicking into the plot, dragging, and releasing. The mask will be created according to the values selected, and will immediately be selected.
If you want to annotate the scatterplot you should save an image and use image editing software, or export the data to a more suitable application.
Yes, I know that way. But, how to create free polygon from scatter plot?
Because, when I dragging, the result is ellipse. Not polygon.
The drawing tools only apply to the product image windows, so you will have to create your desired image with 3rd party tools. There are only a few SeaDAS developers, so it is best if they focus on the remote sensing capabilities (support for new sensors and algorithms) you can't get from widely used general-purpose software.
