[Met_help] [rt.rap.ucar.edu #75347] History for Map of Germany

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Dear met_help,

I have used the plot_point_obs utility to plot some observations
over a WRF mesh  (produced by UPP 2.2). I used this command:

plot_point_obs gdas1.t06z.nc out/plot_point_obs/
gdas1.t06z.2016-01-04_WRFMesh.PS -data_file WRFPRS_d02.06


All looks fine, except that the map superimposed on the observation points
is a bit outdated. It is showing a map with East/West Germany (see
attached). Is there a way to change this? Maybe this is related to the data
I am using? The UPP data comes from a simulation done with WRF 3.7.

Thanks heaps in advance for your help.

Carlos

Carlos,

You raise a very good point!  And yes, there is a way to update the
background map data.  We included some updated map data back in 2012
but
kept the default pointing to the older map data.  I just created a
development ticket to make sure that we change the default to the
newer map
data in the next release of MET.

You need to know 2 things:
 (1) Which config file controls the plotting of map data?
 (2) Where is the map data that is plotted?

The answer to the first question is "ConfigMapData", and the answer to
the
second in "map/update_2012".

But this is a little confusing because you'll find these files in 2
places.  First, look in:
   met-5.1/data/config/ConfigMapData
   met-5.1/data/map/update_2012

However, when you run "make install" these files get copied over into
the
installation directory.  So look in here:
   {install_dir}/share/met/config/ConfigMapData
   {install_dir}/share/met/map/update_2012

And when you run the MET tools, they actually read data from that
installation directory.

Take a look in ConfigMapData and you'll see a list of map data file
names
in the "source" dictionary.  The MET tools which create images plot
these
map data files in the order listed.  So you just need to change these
filenames.  Try using the country_detail_data file, as follows:

   source = [
      { file_name = "MET_BASE/map/update_2012/country_detail_data"; }
   ];

In plot_point_obs, try turning up the verbosity level to 4 (-v 4) and
writing the output to a log file (-log run.log).  Inspect the log file
and
you'll see some log message like this:

DEBUG 1: Creating postscript file: germany.ps
DEBUG 4: draw_map() -> Plotting map data file:
/d1/johnhg/MET/MET_development/
svn-met-
dev.cgd.ucar.edu/trunk/met/share/met/map/update_2012/country_detaildata

Lastly, I've attached a plot showing the resulting image over Europe.
I do
actually see some problems here.  Looks like there's something odd
going on
in Switzerland and Italy.  We'll need to clean that up for the next
release.

Hope this helps.

Thanks,
John Halley Gotway

Dear John,

thank you very much for your fast and detailed answer.
The map looks fine now.
