Abstract
The Curse of LiDAR—Lessons Learned since 2003
Track: Water Resources
Author(s): Al Karlin, Steve Dicks, Ekaterina Fitos
To date, the Southwest Florida Water Management District has acquired over 2 TB of LiDAR data, over 11,000 individual tiles, from four of the largest US LiDAR vendors. The District has seen �the Good, the Bad, and the Ugly� in terms of vertical accuracy (fundamental and supplemental vertical accuracy), tie-edge matching, data filtering and classification (over- and under filtering), and bore-sighting.
This discussion highlights the current specification, details several of the modifications as they evolved, and discusses the future enhancements. Examples of the data deliverables encountered are compliled into the �lessons learned� over the past 6 years. These lessons include, (1) improved methodologies for quality assurance and project management, (2) enhanced specification of breaklines and planimetric data , and (3) the need for synchronic orthophotography to assist in LiDAR interpretation.
