seems that it's ok, v.out.ascii looks good. I think the GUI query
tool is just picking up the nearby cat 15 at -30626,4116558,
versus cat 46 and 47 at -31415|4116150.

see attached screenshot. the two coords you posted are the two
triangles. (d.mark addon)

as for if the wx query tool will show you attribute data for
both overlapping points (like QGIS does), I don't know.


the wx digitizer has a threshold option for snapping, there
doesn't seem to be a similar mouse-proximity adjustment for
the query tool. maybe that doesn't need an adjustment, just a
change from 10px to 5px (even better if it could deal with diff't
screen DPIs)

ps- background (etopo1) is a bit crude as r.in.onearth stopped
working again/JPL changed their tiled WMS again?
pps- er, the vector query tool defaults to edit mode?
