[GEMPAK #DFK-592579]: GEMPAK - Filter on NMAP2 and Gempak script !

Anh Dao,

In order for your plots in NMAP2 and SFMAP to be identicat, the FILTER
should be the same, but your GAREA & PROJ and DEVICE (sizex;sizey) should be 
the same.

The GAREA will affect station overlap. The DEVICE size (the text and symbol 
sizes used will
cause differing amounts of overlap if the output DEVICE has a different size).

If you are using the default display size of the XW of GF device (which is ~70% 
of your screen size),
that may be the largest difference when compared to the NMAP2 canvas area. The 
Canvan in Nmap2
is defined in $NAWIPS/resource/Nmap as:
Nmap*mainw_canvas.width:                1150
Nmap*mainw_canvas.height:               831

If you still have questions, please provide me with your output as well as full 
SFMAP 
settings.

> Inquiry: Hello all,
> 
> In our operational working, we must make some analysis maps for surface and 
> upperair data.
> 
> At first, we draw the isoline with surface and upperair data on the NMAP2 
> interface. In the $GEMTBL/config/prmlst.tbl file, we set (for surface data):
> 
> SFPARM = SKYK:.7:1:132;TMPC;SPAC;SMSL;SPAC;DWPC;SPAC;SPAC;SPAC;SPAC;SPAC
> FILTER = 0.9
> TEXT = 0.857/21/HW
> (The total of parameters is 11)
> 
> Then we have a script on GEMPAK using SFMAP, SNMAP ... to make a final maps. 
> In these script we set:
> 
> SFPARM = 
> SKYK:.7:1:132;TMPC;WSYM:.7:1;SMSL;PTND;DWPC;VSBK;CSYH:.7:1;CTYL;CSYM;CSYL:.7:1
> FILTER = 0.89
> TEXT = 0.857/21/HW
> 
> Because when we open the surface data from NMAP2 to draw on it, the FILTER on 
> EDIT SOURCE tool is automatically change to 0.89. I don't know why ??? But is 
> the reason that I choose FILTER = 0.89 on my SFMAP script.
> 
> The goal of this working is that I want the data that displays on NMAP2 and 
> the data on maps that I execute SFMAP script are totally identical.
> 
> But I don't know why though the parameter in these two case are the same but 
> the data that display on NMAP2 and on the maps (that are made by SFMAP 
> script) are quite different.
> 
> Please show me the solution to my troubles.
> 
> I hope that you will help me as soon as possible. I write to you this 
> afternoon (local time) and do hope that I will receive your answer tomorrow 
> morning.Thank you in advance.
