Re: [ferret_users] GO LAND on curvilinear plot VAR, XLONG, XLAT

Hi Peter,

That region lies entirely within the continent, so there are no land outlines to draw.

To show the location, you could give /HLIMITS and /VLIMITS on the plot command to expand the region, for instance,

fill/hlim=-10:40/vlim=20:60 hgt, xlong, xlat

go land

Hi Ansley
Thank you for your answer.
Both horizontal and vertical axes in the plot have units and labels showing longitude and longitude.
The symbols are defined as follows

yes? fill hgt, xlong, xlat

yes? show symbol xaxis_min, xaxis_max

XAXIS_MIN = "5.5186548"
XAXIS_MAX = "11.05665"
yes? show symbol yaxis_min, yaxis_max
YAXIS_MIN = "45.707306"
YAXIS_MAX = "48.16023"

Here is some more info:
yes? show sym
FERRET_VERSION = "6.84"
FERRET_PLATFORM = "Linux 2.6.32-279.14.1.el6.x86_64 64-bit"
FERRET_PRECISION = "double"
NETCDF_VERSION = "4.2 of Apr 23 2012 15:22:43 $"
FERRET_MEMORY = "100"

go land works with the coads_climatology,

yes? use coads_climatology
yes? fill/l=1 sst
yes? go land

I enclose a pdf output.

Hi,
When you have drawn the plot ,

yes? fill hgt, xlong, xlat

do the horizontal and vertical axes have units and labels showing longitude and latitude? The coordinate variables xlong and xlat shuld have units attributes that indicate they are degrees of longitude and latitude. If they do, then "go land" should work.

The "go land" and "go land_detail" scripts use symbols that are defined when the underlying plot is drawn.  So after your fill plot,  see how these symbols are defined:

yes? show symbol xaxis_min, xaxis_max

Finally, I imagine you have done this, but check that "go land" works for other plots:

yes? use coads_climatology
yes? fill/l=1 sst
yes? go land

Hi
I am plotting WRF output variables, e.g.,

fill hgt, xlong, xlat; go land
or
fill/ i=1:138/ j=1:90 /l=1 psfc, xlong, xlat; go land

as seen in
http://www.pmel.noaa.gov/maillists/tmap/ferret_users/fu_2013/msg00110.html

The variables are plotted, but the 'go land' command does not overlay country borders, although there is no error message.

Can anyone help?
