[ncl-talk] Help in reading a shapefile non-spatial attribute with NCL

[Orestis Speyer]

Hi everyone,

 

I want to extract an attribute (as defined in the gis world) from a
shapefile to use it for subsequent calculations.

This attribute is non-spatial and it is named AREA_KM2.

When I use the standard NCL syntax for variables, i.e. 

 

surface = f->AREA_KM2

I get

variable (AREA_KM2) is not in file (f)

 

Is the shapefile non-spatial attribute treated differently?

I am looking at the NCL examples but I could use some help.

 

Cheers to all,

Orestis Speyer
