[gradsusr] Google maps KML

[Mike Manning]

No worries,

 

I just had a brainstorm and got it sorted - I changed my ccols and clevs to
the following:

 

'set clevs -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 50'

'set ccols 50  51 52 53 54 70 55 56 57 58 59 -1 -1'

 

 

So anything above 1 will be set to a value of -1 which is transparent.
Working a treat now! I just gotta work out transparency then will be good to
go.

 

Cheers, Mike

GrADS is picking up the grid size of your input data set.  I suppose you
could use "lterp" with a fake grid that is really high res, make a new
variable interpolated to that higher res, then display that.

Hi Jim,

 

Thanks for the feedback - Yeah I tried maskout originally however it
produced quite ugly results with jagged edges - Is there a way to smooth the
edges of maskout?

 

Cheers, Mike

Hi Mike,

I think the -poly option will produce transparency at missing values, so you
will need to set values that are currently displayed as grey to "missing".
You can do this using the grads function "maskout".

Hi all,

 

I'm using a grads script to generate a KML file that I am using on Google
Maps using the 'set kml -poly' option.  I've set clevs and ccols using
custom colours:

 

'set clevs -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0'

'set ccols 50  51 52 53 54 70 55 56 57 58 59'

 

This is for lifted index, so I only want to display from -10 to 0 on the
chart which it does but the problem is that ugly grey background that I
can't get rid of.  Does anyone know a way around this or is it a glitch in
Grads with KML that I just have to put up with when using -poly?

 

Cheers, Mike
