I want to analyze viewshed from some point. For that, I installed the viewshed plugin, and run it.

elevation raster: dem
observation points: observer(only one point)

But it just shows the message "One object selected in the layer observer.", left bottom of QGIS window.

And there is no error message and no result file.

And the observer layer really was selected one point.

Example

  • As an alternative you can use GRASS gis r.viewshed. I see it to the right in your screenshot – BERA Mar 15 at 8:13
  • Please share with us your data. I just tried selecting one feature, changing crs and other things and it works always. Just brakes when you try the viewshed to a very long distance or with a very high resolution DEM. – César Arquero Mar 15 at 12:05
  • thank you. maybe high resolution DEM is problem maker...^^ – Jung TaeJun Mar 17 at 3:21
