• LiDAR 101 - Introduction to LiDAR technology, its accuracy, importance of tying to geodetic control, and QA/QC   (Parrish)
• Accuracy requirement in coastal applications - sea level rise and shoreline (Waters)
• Quality Control of LiDAR - elevation data used in floodplain mapping (Thompson)
• Control, Acquisition, and Post-processing of LiDAR Data for Corridor Work -utility and transportation (Sorrels)
• Green, Waveform LiDAR in Topo-Bathy Mapping (Nayegandhi)
• National Enhanced Elevation Assessment (NEEA) - Introduction to NEEA effort, discussion of LiDAR applications and economic benefits (Snyder/Maune)

The morning presentations for this workshop will be available as a webinar, but the afternoon session will not since it will consist mainly of break-out sessions.

The National Geodetic Survey’s National Height Modernization Program has been working with local agencies and academic institutions across the country to improve their capacity to use new technology to derive accurate heights referenced to the National Spatial Reference System. With improved geoid models, Global Navigation Satellite Systems (GNSS) like GPS can be used to measure heights to 2 cm accuracy.  Accuracy of digital geospatial data collected with new remote sensing technologies has also improved in recent years. Products and activities that need accurate digital elevation data, like national DEMs, floodplain maps, hydrologic modeling, and coastal inundation studies, are relying more on LiDAR surveys.  What are your accuracy requirements, and how can you be sure the LiDAR data you have was collected to meet those requirements?

For this 1-day workshop, experts in LiDAR data acquisition, standards, procedures, and applications will share their knowledge and insights to enable you to evaluate the LiDAR data you or your customers are using. At the end of the day you will:

1. Learn about the National Enhanced Elevation Assessment being performed to evaluate requirements of Federal and local agencies and private industry.
2. Understand why vertical accuracy and tying to vertical ground control matters in collection of LiDAR data.
3. Understand different standards that have been developed for LiDAR.
4. Learn about various applications using LiDAR data and their vertical accuracy requirements.

A detailed program is being developed with speakers from USGS, NOAA, and other agenices. The agenda will be posted soon.
