New Win32 Release of GrADS v1.9.0-rc1 (shapefiles)

[Stephen R McMillan]

Hello Arlindo,

I was able to install this latest release with no problem. I'm glad to see 
it now includes shapefile functionality. However, contrary to the included 
documentation, using the 'set line...' option appears to have no effect on 
either line style or thickness--just color. Unlike the default map 
drawing, the shapefile boundaries (when using shp_lines) appear much too 
heavy for some uses, especially on screen and for large geographical 
areas. I did have "mpdraw" set to off, as instructed. I tried image output 
with both primtim and gxyat, with similar results (that is, no change in 
line style or thickness). Example of what I did after opening model.ctl:
'set mpdraw off'
'set line 4 1 1'
'shp_lines admin98'
[image displayed as expected, other than polygon line thickness]
'gxyat c:\wx\out\shptest1.png'
'set line 4 3 6'
'shp_lines admin98'
[image displayed same as previous image]
'gxyat c:\wx\out\shptest2.png'
[identical to shptest1.png]

It would be very useful to be able to control line style/thickness. 
Perhaps another user can confirm what I got.  Assuming it works for you, 
do you have any suggestions?

Also, could you point me to an example or two on how to use the shapefile 
"object" option. Do I have to create a separate shapefile object, or are 
there objects within the included admin98 shape files (for example). If 
so, how do I specify one or more objects?

Thanks--
Stephen McMillan

New Win32 Release of GrADS v1.9.0-rc1







All,


  I just uploaded to sf.net a new Win32 GrADS release:


     
http://sourceforge.net/project/showfiles.php?group_id=161773&package_id=270750

Notice that Win32 GrADS now has its own packaged called "grads-windows". 
See the ChangeLog for additional info.

   This version fixes some bugs with DOS-style text files, and includes 
Release 2 of the OpenGrADS extensions, with Grib-2 and Shapefile support 
(as well as an improved "fish"). To quickly checkout the new features:

Grib-2:

   ga-> g2_open ../data/model_25.gdf
   ga-> d g2(tmpprs)

or with the % shorthand

   ga-> % d tmpprs

Shapefile:

   ga-> open ../data/model.ctl
   ga-> d ts
   ga-> shp_polyf admin98

Fish:

   ga-> set lev 200
   ga-> d fish_psi(ua,va)
   ga-> clear
   ga-> d fish_chi(ua,va)

   For documentation,

          http://opengrads.org/doc/

   Let me know of any problems.

     Arlindo
