v19 v20 18 18 After running the ALSPP check the % of first returns column in the main window. This should be high (probably >95%). If not then it may be an indicator to problems with the data (such as a large % of cloud coverage) 19 19 20 === Data QC and further processing===20 === Data QC === 21 21 22 22 [wiki:Processing/Lidarqcprocedure Full QC procedure]. 23 23 24 The final stages of the processing are to quality check the data and filter out noisy points. T o do this we use the Terrasolid package within the Microstation CAD environment, andcan be very time consuming. See [wiki:Processing/TerrascanTips tips] on using Terrascan and also [wiki:Sensors/LeicaLIDAR/MashUp#QC here] for further notes from leica.24 The final stages of the processing are to quality check the data and filter out noisy points.
