[GRASSLIST:4952] Areas in dig_att

[Alexandra Zamparas]

Hello!
Just wanted to start by thanking the people who have been answering
my questions every time, all suggestions have been very helpful. Now,
I'm looking at the dig_att file of my subbasins map and I can see the
coordinates (of the area centroid?), if it is an arc or line and the
cat.number.

Issue 1: How do I get the areas of the subbasins into the
attribute table?

Issue 2: Why do the categories appear as even numbers? Isn't the
category number supposed to be the unique-id?

Issue 3: Is it right that some category numbers appear more than
once?

For the purpose of testing your patience :), I'm copying the file
below.

Thanks in advance!

Warm regards,
Alexandra
