Elevation Derived Hydrology: How it is made and what you can do with it.

DESCRIPTION

Pennsylvania will soon have statewide, 3DEP-compliant QL2 lidar. These QL2 data offer a chance to create, standardize, and update high resolution hydrology. The Hydrology Dataset (PAHD) by the Bureau of Geological Survey(BGS)) to develop Elevation Derived Hydrology (EDH) has been developing for a number of years, and is beginning to produce hydrography that is directly derived from lidar. PAHD and lidar derived EDH not only ensure that mapped rivers stay in their valleys, but also shows smaller headwaters that will be important for watershed protection, flood predictions, and water quality.

This presentation will discuss what the new EDH datasets will look like and how they are created. It will explore why they are different from previous hydrography datasets that are currently being used across Pennsylvania and how they can be applied to answer real world questions for a few use cases in Western PA, including peak flow calculation, 3D visualization and integrated watershed planning.

PRESENTER(S)

As a Senior Program Director for NV5 Geospatial, Dr. Andrew Brenner brings together company-wide skills to produce reliable solutions in geospatial analysis. Andrew is a specialist in natural resource management, with experience in forestry and agriculture in tropical and temperate environments and he has been involved in user needs assessment work for multiple forestry organizations, including the Forest Service and Michigan Department of Natural Resources. He has led projects on forest inventory, watershed modeling, wildlife species habitat assessment, wildfire risk assessments, and forest health. In addition, Andrew has led the development of feature extraction work in forest stand mapping, crop identification, ecological alliances, and vegetation health assessments for federal mapping programs such as the National Land Cover Dataset (NLCD) for USGS, and the Coastal Change Analysis Program (C-CAP) for NOAA Coastal Services Center.


Matt Mercurio is the co-founder and Geospatial Technology Officer at CivicMapper, a Pittsburgh based mapping technology company. Matt specializes in implementing innovative approaches for solving tough problems using location information and geospatial technology, and has “seen it all” during his 25 years in the industry. Most recently Matt has been working on creating wayfinding application for pedestrians, integrating municipal storm and sewer infrastructure datasets for 3 Rivers Wet Weather, and establishing GIS as a shared service at Quaker Valley COG. Matt enjoys pushing the edge of consumer grade technology, like phones and drones, to accurately recreate 3D models of surface objects for stormwater studies. Matt is actively engaged in the PA GIS community acting as the current VP of PAMAGIC, serving as the co-lead on the statewide PA Elevation Working Group Hydrology Application Network, and is a certified GIS Professional (GISP).


Drew Meren has been in the Geospatial space for more than 20 years. A graduate from Towson University, with a Geography degree, he started his geospatial career working for municipalities, Baltimore County, MD and Prince William County, VA near Washington DC. Drew began working in the private sector reselling geospatial data like contours, Mobile and aerial orthophotos and LiDAR. He primarily focused on customers in the Northeast part of the US and New England due to his upbringing in NYC and Western Mass. Drew joined NV5 Geospatial powered by Quantum Spatial (NV5G) in 2016 as an Account Manager focusing on the East coast, from Virginia to Maine. With several statewide contacts in aerial and LiDAR data collections, Drew is looking to showcasing NV5G's LiDAR derivatives to municipalities. Be sure to come to NV5G virtual booth to talk further with Drew about data collection and emerging technologies.
