Problems with wrapTo180, creates lines on map
显示 更早的评论
Hello,
I have a longitude vector that I want to convert from 0-360 to -180 - 180 The data shows perfectly find on a global map when in its original 360 form, but once I use wrapTo180, there seems to be lines all across my global map.
Has anyone else had this problem?
If so, how do I fix it?
Thank you,
Melissa

Can you upload an image with lines? Can you repeat the problem using dummy data such as Z=peaks(180)? If so, upload some code that we can use to replicate the problem.

Melissa, I'm having the same issue as you are here. Did you ever get resolution to this?

Instead of wrapping your longitudes, try using the maptriml function with latlim = [-90 90] and lonlim = [-180 180]. Because these limits span the globe, this won't really trim away any data. What it will do is cut your data on the 180-degree meridian. This cut should eliminate the spurious lines that you're seeing across your global map.
