Community-led hydrography update projects have continued in the past years throughout the US. In parallel, a Dec 2014 call by USGS management for the development of integrated Elevation-Hydrography
data initiated a few pilot tasks to explore production issues in hydrography extraction from lidar. This talk explores the creation of a distribution facility for Best Practice resources, pointing to benefits in
efficiency and quality for any upcoming update project.
Consideration of the characteristics of such a facility in several areas are covered: Tool development and availability. Workflow protocol review, vetting and distribution. Data model constraints and capability domain. Community participation in Quality Control.
The talk takes as it’s foundation Best Practices Recommendations gathered by the practitioner community and presented at the AWRA 2014 Conference. These were part of the input that led to recent USGS

Presentation at 2018 AWRA Spring Specialty Conference: Geographic Information Systems (GIS) and Water Resources X, Orlando, Florida, April 23-25, http://awra.org/meetings/Orlando2018/
