I am getting strange vertical lines on my hillshade, anyone experienced anything similar?

I am very new to ArcGIS.

  • Can you say more about the provenance of your hillshade to aid troubleshooting? – metasequoia Aug 1 '16 at 0:24
  • Hi! I used DroneDeploy and a Phantom 3 drone to collect the elevation data, which I then imported to ArcMap and used spatial analyst to create the hillshade. – user6117907 Aug 4 '16 at 9:16

It is possible that these artifacts are a result of Nearest Neighbor sampling, which does well for categorical data, but is not ideal for continuous data. Selecting a resampling method other than Nearest Neighbor, such as Bilinear or Cubic convolution many provide a smoother looking Hillshade.

Long time coming, but I solved this problem by applying the Focal Statistics tool to the DEM before hillshading :-)

Thanks everyone for the help! Al
