Issues identified in the previous posts AOP Lidar Data Quality Notification and AOP Lidar Data Quailty Notification - Update have been resolved.
All sites and data products identified as having misclassified noise have been reprocessed. We have implemented a solution so that new sites collected with the Galaxy Prime sensor no longer display abnormally high noise levels, as exhibited when we first started operating this sensor in 2021. The improved data quality was achieved by implementing new noise-filtering algorithms in Teledyne Optech's Lidar Mapping Suite, and by slightly modifying the flight plans.
We note that completely eliminating all misclassifications is not feasible through our automated classification routines. If users find additional misclassifications, please share the dates and sites with issues through the Contact Us form. NEON can also provide information on ways to manually remove remaining noise points.
