You can create a map of these points contining the elevation as
attribute. Once you output this map you could sort points using
the elevation values.<br>
<br>
you can do this for instance using v.to.rast to convert the points
to raster, them combine this map with elevation using r.mapcalc
(assigning elevation to the points), and them output the map using
r.out.xyz.<br>
To sort the points you can use any sort program or a spreadsheet.<br>
<br>

<div>I have a collection of points that represent the centerline
of a river. I need to output them in upstream to downstream
order (or the reverse). A simple v.out.ascii does not do this
because of the channel meanders. It's critical to get the x,y
locations of these points in the correct order.</div>
