Phoenix LiDAR’s SpatialExplorer’s LiDARSnap strip alignment tool was tested using a challenging mobile LiDAR dataset collected along a rural state road, Natchez Trace Parkway, near Mathiston, Mississippi. Approximately 17.5 km of the parkway was mapped using the RANGER Flex dual-head mobile LiDAR mapping system.
Of the total mapped area, nearly 85% was covered by a dense tree canopy, which posed a significant accuracy challenge due to the limited availability of GNSS signals. LiDARSnap was utilized not only to calibrate the relative accuracy of the two passes but also to georeference the scan in relation to leveled control.
This paper discusses the processing workflow, results, and capabilities of LiDARSnap in challenging, GNSS-denied environments.
