Hello,

 

I would like to compare the data displayed in the LRO LOLA images (e.g. LDEM_80S_20M) to some other data

and therefore I would like to use the same color scale.

 

Can I download the color scale used in the LRO LOLA images anywhere on this site?

Maybe in a format I'll be able to use in MATLAB?

 

 

Regards,

EBonacker

No, the color scale is not in the archive. I'll ask the LOLA team to provide something.

EBonacker,

Here's the LOLA color map as a cpt file, from the LOLA team.

For using cpt files with Matlab, I found the following on the Matlab Central web site:

http://www.mathworks.com/matlabcentral/fileexchange/28943-color-palette-tables-cpt-for-matlab

Hope this helps you.

Hello,

 

thank you very much for the cpt file.

The color scale still doesn't look exactly the same as in the LOLA-images as there's

a part of black/gray at the bottom which isn't in the scale in the LOLA images,

but we'll try to fix that.

 

Thank you, again.
