What's the best way to do resize for radar image

[qch2041]

I have a png image of radar data, size 1850x2048, I need to convert it to gif format of size 480x480 ( I have source code to read the data from gif image, then convert to another data format. ). I know there are many ways to do (resize, adaptive-resize, scale, sample, resample, ..., etc.) I am wondering what is the best way to the conversion in order to keep the accuracy of radar data as much as possible?

There is no one best answer. I would use either -resize or -distort resize with whatever filter works best for you.
