Re: pollutants distribution over traffic map

Dave,

I missed the space between "I-" and "75". Your script works.

Thanks,

cl

CL,

Please insert exactly one space between "I-" and "75". The string match function requires an exact character match, and those strings in the highway shape file are peculiar.

I get all three requested highways with my version "shapefiles_12b.ncl", which is attached:

Hi Adam,

I did something wrong in last email. I tried your revised shapefiles_12.ncl by changing highways to I-75,I-85
highways = (/"I-75","I- 85","I- 285"/). But the script only draws I-85 and I-285, and didn't draw I-75. I am attaching the plot. Please check it.

Thanks much,

cl

Hi CL,
My apologies, I missed your previous email saying you tried switching
the interstates to Georgia interstates...
