[gradsusr] Info about shape files

[Francesco Piani]

Thanks for the reply. 
But MeteoInfo seems to be a different tool than GrADS. I wonder if GrADS can use shape also for maskout or other statistical operations.

Hi Francesco, 

1. Shape files could be used as maskout layer in MeteoInfo which is free avaliable at http://www.esnips.com/web/MeteoInfo . You can even use one or more shapes in a shape file as maskout through output the shapes to a .wmp file. In this way, the plot will be masked exactly by the border lines of the shapes. 

2. With MeteoInfo, you can output the shapes of a shape file to a maskout grid data which could be used in maskout() function of GrADS. 

The detailed information could be found in the help document of MeteoInfo. Only polygon shape files are valid for above application. 

Best Regards!
