Hello!<br>
<br>
</div>
We have a linear feature of ~60km which is a future
path of a road having ~400m in size and being quite
curved.<br>
<br>
<br>
</div>
I'd like to create a mask for raster operations that
fits this shape.<br>
</div>
Hull creates a convex shape which is hice but still have
many "empty" space involved. This is sparse lidar data,
anyway.<br>
<br>
</div>
Is there a techique to create such a raster mask/map?<br>
</div>
<div><br>
</div>
Pure rasterization won't work since it has holes (see also
vectorized coverage at 10m resolution, zoomed into a "hole".<br>
<br>
</div>
<div>I'd need something like a <u><b>"concave hull"</b></u>
function :)<br>
</div>
</div>
</div>

Hope about the addon:<br>
