Resetting 'Noise' classified points to unclassified

jddewitt

I noticed that in the Automatic Classification of Ground Points tool there is a checkbox to reset existing ground points to unclassified at start.  This is super helpful because it allows me to play with the parameter settings without having to create a bunch of new las files. However there doesn't seem to be a similar checkbox for the Automatic classification of Noise Points tool. Is it there and I'm just missing it? Or is this planned for a future version?  Thanks

Hello,

I have opened feature request #17684 so we can consider adding a check box to reset existing noise points to unclassified to the Automatic Classification of Noise Points tool.  We will post a message on this thread when the status of this feature request changes.

Cheers,

Bob

I have updated the Lidar noise classification dialog to have an option for resetting existing noise points prior to performing the operation. I have placed new builds with the latest changes at http://data.bluemarblegeo.com/downloads/global-mapper/dailybuilds/ for you to try.

This is of interest... The common topic as stated in the DEM Manual and Noaa's https://coast.noaa.gov/digitalcoast/_/pdf/Refinement_of_Topographic_Lidar_to_Create_a_Bare_Earth_Surface.pdf and https://coast.noaa.gov/digitalcoast/_/pdf/lidar101.pdf page Page 13/ 36.  The corn row found was likely due to radiometric noise or overlap between the different flight dates.  A quick analysis running slope or looking at the DEM / DSM showed the impacted areas.  I like above would like to see more details about the play button feature options.

Hello GeoND,

Was your last message meant for this thread? I'm not seeing any context for it in the rest of the thread.
