<div>How are you seeing that points convert to an area? An area
encompassing the points?? In which case you probably want
v.hull (<a

moz-do-not-send="true">https://grass.osgeo.org/grass76/manuals/v.hull.html</a>).</div>
<div><br>
</div>
<div>One further suggestion, consider changing your variable
names for, uh, readability??</div>

don't remember the workflow converting corner points into an

no saved example here.<br>

When I try the sequence:<br>
<br>
v.to.lines in=anal_corners out=anal_bnd<br>
v.build map=anal_bnd opt=build<br>
v.centroids in=anal_bnd out=anal_area<br>

grass tells me 'input vector map contains no boundaries'.<br>

What have I missed?<br>

<p>v.to. lines is *not* what you want. That module takes a polygon
and converts the boundaries to lines.</p>
<p><br>
</p>
<p>If you want to go straight from the point coordinates to a
polygon, you can use the GRASS standard ASCII format and pipe
directly to v.in.ascii:</p>
<pre>echo "VERTI:
B 1 5
-123.940000 45.150100
-123.940000 45.145400
-123.960000 45.145400
-123.960000 45.150100
-123.940000 45.150100
1 1
C 1 1
-123.950000 45.147500
1 1" | v.in.ascii input=- output=analysis_region format=standard
</pre>
Check the ASCII vector format page:
