Masking Operations:
(Scalar/Vector) POSMASK([Scalar Operation]){AND,OR,NOT}... - Calculate a Positive Mask to filter req.
Scalar/Vector op.
(Scalar/Vector) NEGMASK([Scalar Operation]){AND,OR,NOT}... - Calculate a Negative Mask to filter req.
Scalar/Vector op.
Masking operations are an exciting new addition to WINGRIDDS operations. They provide a way to create a plot of
Scalar or Vector which only shows data (POSMASK) where other complex parameters are satisfied or it can create
a plot of Scalar or Vector which blocks plotting data NEGMASK) where other complex parameters are satisfied.
The parameters are evaluated using logical operators AND, OR & NOT. Examples of both Positive and Negative
masking will be showed below.
Example command for POSMASK;
WIND POSMASK(TEMP GTLT 8 12) AND (RELH GRTN 50) OR (VVEL GRTN 01)
Example command for NEGMASK;
MIXR CTFC NEGMASK(TEMP GTLT 8 12) AND (RELH GRTN 50) NOT (DVRG LSTN 0)
How it works:
POSMASK creates a 'Positive' mask created from multiple SCALAR commands within parenthesis which are
separated by MASK BOOLEAN OPERATORS of 'AND', 'OR' & 'NOT'. The resulting mask will control where the
first SCALAR or VECTOR is plotted.
NEGMASK creates a 'Negative' mask created from multiple SCALAR commands within parenthesis which are
separated by MASK BOOLEAN OPERATORS of 'AND', 'OR' & 'NOT'. The resulting mask will control where the
first SCALAR or VECTOR is 'NOT' plotted.
Multiple SCALAR commands can be strung along with multiple BOOLEAN OPERATORS as needed to the 555
Character length limit. All GRIB or Diagnostic calculated scalar parameters can be used.
Hi-Rez Maps:
Hi-Rez maps can now be drawn with independent colors, widths and line patterns. Also, a collection of country
state/province maps for the whole world have been included for plotting. These, also, can be plotted with
independent colors, widths and line patterns. The state/province map files are in a separate directory
(WINGRIDDS\DATA\Country_Provinces). As a result of these changes, the MAPFILE.DAT file in the
WINGRIDDS\USER directory has been changed with documentation included in the file. As usual, the
MAPFILE.DAT can be modified by the user for their individual needs. A copy is presented here - notice the use of
exclamation points (!) for comments and to nullify a specific line from being used :
***********************************************************************************
!
! This file lists all Hi-Rez map files to be plotted in WINGRIDDS
! when the option is selected in the WINGRIDDS Properties. If an optional
! entry is not used, the default parameter from the WINGRIDDS
! Properties is used. Maps will be drawn in the order they are listed.
!
! The format is as follows:
!
! 1) (required) first is the file name from the DATA/ directory
!
! 2) (optional) color the map info will be plotted in.
!
There are 8 basic colors which can be used. The colors are:
!
!
black
!
red
!
yellow
!
green
!
cyan
!
blue
!
magenta
!
white
!
! 3) (optional) line width - in pixels
!
! 4) (optional) line pattern style the map info will be plotted.
!
There are 8 line styles which can be used but the
!
represented number is what is used inline. The styles are:
!
!
SolidLine
-0
!
Dotted
-1
!
Dashed
-2

DotDash
-3

-6
!

!
!
!
Individual Hi-Rez country province files are available as well & reside in
!
the DATA\Country_Provinces directory. These files may be plotted with the
!
same color & pattern options as listed above. To include these files in the
!
map plotting, you must include the directory in the file string as follows:
!
!
Country_Provinces\Guatemala_Prov.MAP green 1 2
!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!COUNTY.MAP cyan 1 1
!NOAM4-RIV.MAP blue 3
!NAIH.MAP red 1 2

Country_Provinces\Mexico_Prov.MAP red 1 2
Country_Provinces\Guatemala_Prov.MAP green 1 2

Country_Provinces\Panama_Prov.MAP red 1 2
Country_Provinces\Nicaragua_Prov.MAP cyan 1 2
****************************************************************************
Things are really coming together and I hope everyone finds these additions improve the usefulness of
WINGRIDDS. I am starting on the updates to the WINGRIDDS Users Guide documentation to look for a final
release of WINGRIDDS v5.0 this winter. Remember, if you find any errors, please be complete in your description
of the problem & what you did to cause it to happen.
Thanks in advance & enjoy!
