Cutting Culverts into Lidar DEM’s

Lidar has become an important tool for management of water resources and for designing mitigation efforts for localized flood events.  While regional issues have driven topographic mapping efforts for counties, watersheds, and floodplains, the high accuracy and high definition Lidar surface models are now being applied to micro-drainage solutions.  However, the lack of culvert information with these surface models can present an issue for proper …
