v.out.ascii: layer=2 column output wrong

[hamish]

Hi,

when trying to do v.out.ascii for layer=2 I get tons of

WARNING: Feature has more categories. Only first category (1) is exported.

One for every single point. It's rather annoying to see so many and I'm not really clear about what it actually means. Will only layer 1 be exported even when I specifically asked for layer 2?

example:

#spearfish
v.in.ascii out=surv_track format=standard -n << EOF
L 3 1
 608119 4915294
 606085 4919979
 599926 4920470
 1 1
EOF

# v.to.points creates 2 layers
v.to.points in=surv_track out=surv_pts dmax=100

v.out.ascii surv_pts layer=2
[noise]

(in my real case I've added a new column to layer 2 and use the new v.out.ascii columns= to export those values)

?

thanks, Hamish

Ah, I (think I) see what the warning means,

v.out.ascii tmp_point_9669 layer=2 column=width  2> /dev/null | head

it means that it is mixing up cats from layer=1 and layer=2.

layer=1 cat is always 1 in this map (orig cat of v.to.points input line) and so it retrieves the layer=2 cat=1 value (594.622) for all points :( instead of by layer 2 cats:

v.db.select tmp_point_9669 layer=2 | head
cat|lcat|along|width
1|1|0|594.622314
2|1|99.876312|550.689599
3|1|199.752625|460.65393

changing title of bug & increasing severity.

Hopefully fixed in r35918 (devbr6), r35936 (trunk) and r35937 (relbr64).

seems to work now, thanks.
