Topical Session Title: New and Emerging LiDAR Technologies: High Density and TopoBathymetric LiDAR Sensors (organized by Dr. Al Karlin, SWFWMD)
Abstract:
As part of a topical session devoted to new and emerging Light Detection and Ranging (LiDAR) technologies, this presentation focuses on the challenges present when wetlands are a major component of the landscape, particularly in Florida. Examples: A “standard” driver for determining acquisition timing has been “leaf off” conditions, which may not be relevant in our sunny clime especially in wetlands. A far more relevant driver is hydrology. Wetlands are not always “wet”; simple models based on historical stage records are being used in the Upper St Johns River Basin (USJRB) to “fly when it’s dry” – a better driver for LiDAR acquisition. The problem of dense vegetation obscuring true ground has been successfully addressed with high point densities and 55% flight overlap, among other sensor specifications. Lastly, successful results involving reprocessing and recalibrating older (2012) LiDAR data, also in USJRB wetlands (at a significant cost savings compared to re-flying the project area) will be presented.
