Colormaps used in LRO LOLA images

Recommended Posts

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,

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:

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.
