overlay a radar image

Chao_Jiang

Hi all,
I'm using matlab to overlay a radar image on my ice rigidity B field.
This is my code:
plotmodel(mds,'data',mds.results.StressbalanceSolution.MaterialsRheologyBbar,'layer',10,'overlay_image','moa125_2014_hp1_v01.tif','overlay_xlim',[min(mds.mesh.x), max(mds.mesh.x)],'overlay_ylim',[min(mds.mesh.y), max(mds.mesh.y)],'overlay_xposting',100,'overlay_yposting',100,'alpha',2.5)

However, it did not work and I got the following warnings:

WARNING: option alpha was not used
WARNING: option overlay_image was not used
WARNING: option overlay_xlim was not used
WARNING: option overlay_xposting was not used
WARNING: option overlay_ylim was not used
WARNING: option overlay_yposting was not used

I'd like to seek your help, and I have a few questions regarding the overlay option in plotmodel:

Are all four of these: the 'overlay_xlim', 'overlay_ylim', 'overlay_xposting' and 'overlay_yposting' indispensable if I'd like to use my own radar image?
What are the definitions of these two: 'overlay_xposting' and 'overlay_yposting' , and how should their values be determined? (I've checked plot_overlay and radarpower.m but still have no idea about that.)

Any response is appreciated!

Thanks,
Chao

Hello Chao

I think you forgot to add the option 'overlay',1 otherwise plotmodel does not know that you want to have a background image on your plot. Try it!

Thanks Mathieu! The overlay plot works after adding 'overlay',1.
