Software -------------------------- Count GeoCue LAS Updater 4 -------------------------------------------------- System ID: Output of what is populated in the header information for system ID. Often accounts for what sensor has collected the data; however, this field may also account for files that were the result of extraction, merging, or modification. Lists information populated in the system ID header and a count of each occurrence. System ID ------- Count ALS70 4 -------------------------------------------------- Point Data Records Referenced in Public Header Block Matches a Count of Point Data Records: A true/false output and file count for occurrences of matching information between the data and its header block. Matches ----- Count True 4 -------------------------------------------------- XYZ Attributes of Header Match XYZ Attributes of LAS file: True/false output with a count of each occurrence of matching information between the data and it’s header block. True: 4 False: 0 -------------------------------------------------- Return count in the file agrees/disagrees with returns in the header information: File count indicating if return counts agrees/disagrees. Ret count agrees: 4 Ret count disagrees: 0 -------------------------------------------------- Scan Angle Rank Min/Max: Minimum and maximum scan angle rank found throughout the dataset are given below: Min Scan Angle Rank: -25 Max Scan Angle Rank: 23 -------------------------------------------------- Intensity Min/Max: An integer representation of the pulse return magnitude given in the minimum and maximum values found across the dataset. Min Intensity: 0 Max Intensity: 65535 -------------------------------------------------- GPS Time Min/Max: The overall minimum and maximum GPS tile values found across dataset and represented in a readable format. Min GPS Time: Sun Feb 26 13:54:40 2017 Max GPS Time: Sun Jan 7 19:03:37 2018 -------------------------------------------------- All Legacy Fields Are Set to Zero in 1.4 Files: A boolean representation if point records are set to zero in all 1.4 LAS files with a count of legacy points. True: 0 -------------------------------------------------- Classification values used: A list of all classifications used across the dataset.
