3DGeo Hydrologic Landforms and Hydrography Workgroup:  Member Bios

See the workgroup's webpage for more information about the group and member contact info.


  1. Ann Banitt is a licensed professional engineer in the State of Minnesota. She graduated in Civil Engineering from the University of Minnesota-Twin Cities. Ms. Banitt has worked for the U.S Army Corps of Engineers Saint Paul District since 1991 and specializes in hydrologic and hydraulic engineering. Ms. Banitt serves as a representative for the USACE’s National Committee on Hydrology, the Mississippi River Valley Division Regional Technical Specialist in Hydrologic Modeling, Statistics and Risk, and is a member of the Climate Preparedness and Resilience Working group. Her interests include hydrologic modeling of extreme events, reservoir modeling, statistical hydrology and climate change impacts on inland hydrology.
  2. Andrea Bergman is a GIS Hydrologist with MNIT@DNR working with the Ecological and Water Resources Division (EWR). Her educational background is in Geography, GIS, and Water Resources. She is currently a technical data steward for EWR hydrography data products including the Public Waters Inventory, National Wetlands Inventory, and Lakes Database. She also spent nine years as the data administrator for the DNR Water Monitoring and Surveys unit, responsible for the collection, development, analysis and publication of stream monitoring data.
  3. Jen Crea is with the Data Administration & GIS Unit at MNIT@PCA. She has supported hydrography work for Pollution Control since 2000. She uses the National Hydrography Dataset (NHD) to produce datasets to support water quality programs related to standards, assessments, monitoring, and impairments. She is the State Steward for NHD.
  4. Matt Drewitz is a hydrologist and serves as the Measures and Outcomes Coordinator for the Board of Water and Soil Resources. He graduated from Minnesota State University-Mankato with an M.S. in Environmental Science and from Gustavus Adolphus College with a B.A. in Biology. Matt has 20 years of experience working with local and State government agencies on water quality related issues. He is currently coordinating two LiDAR-dependent projects: the Tillage and Erosion Survey Project and the continued development of the PTMApp software program.
  5. Tom Hollenhorst is an ecologist with the U.S. EPA Office of Research and Development, Mid Continent Ecology Division, in Duluth. He has been applying GIS and remote sensing technologies to ecologic research since 1991. He’s particularly interested in utilizing high resolution elevation data for improved watershed delineations, better hydrologic models, and improved ecosystem assessments.
  6. Brandon Krumwiede serves as the Great Lakes geospatial coordinator and remote sensing specialist with the Baldwin Group at NOAA’s Office for Coastal Management (OCM) located in Chanhassen, MN. He received his M.S. in geography from the University of Montana, his B.S. in geography from Bemidji State University, and currently holds both a GISP and Certified Geospatial Intelligence Professional Remote Sensing and Imagery Analysis certification. He currently works with topo/bathy LiDAR, multibeam, multispectral, and hyperspectral datasets to address various coastal management issues.
  7. Rick Moore is a GIS Analyst - LiDAR Data Steward with Minnesota IT Services Partnering with the Department of Natural Resources. He graduated from MSU Mankato in 2004 with an M.S. degree in Geography specializing in Geographic Information Systems (GIS) and has a BS degree in Geography from the University of Minnesota in 1994. He focuses on hydro-modification of digital elevation models (DEM) and terrain analysis using DEMs derived from LiDAR. These hydro-modified DEMs are inputs for hydrologic modeling as well as in applications that target potential locations for agricultural conservation practices. Prior to coming to MNIT@DNR, he worked at the Water Resources Center at Minnesota State University Mankato from 2007 - 2015.
  8. Sarah Porter: Bio will be added
  9. Christiane Roy is a GIS Specialist with the USDA Natural Resources Conservation Services (NRCS). She graduated from North Dakota State University with a Masters in Wetland Ecology and later acquired her Professional GIS Degree. She worked for the Kansas Department of Wildlife and Parks as the State Furbearer Biologist for 8 years. In 2004 she moved to Minnesota to work for NRCS as a GIS Specialist. Following LiDAR acquisition in SE MN, Christiane focused on developing models that utilized LiDAR to improve site-specific watershed modeling and conservation planning. She also trains and supports NRCS and SWCD field staff on use and application of GIS. Today every planner in NRCS uses LiDAR for deriving conservation practice location. The development of the ACPF models was an important milestone for NRCS and its dependency on hydro-modeling makes it even more crucial to finalize a Hydro-DEM product statewide.
  10. Kiah Sagami is a GIS Analyst at Houston Engineering, Inc. (HEI) with more than 10 years of experience performing GIS analysis, mapping, and database design. Kiah also uses her GIS skills for cartographic mapping, floodplain mapping, parcel mapping, and geo-database editing. Her GIS efforts often center around water resources; whether it be creating hydro-conditioned digital elevation models or gathering land use data, Kiah’s mapping abilities are integral to a variety projects.
  11. Jamie Schulz is the GIS Coordinator with MNIT@DNR with the Section of Fisheries. She started with the DNR in 1999 working as a Resource Specialist for Parks while earning her Masters in GIS from Saint Mary’s University. She has worked for the Section of Fisheries since 2001 and concentrated on DNR’s watercourse GIS data layers for the last 17 years, including the Stream Routes with Kittle Numbers and Mile Measures layer and all derived data (Designated Trout, Strahler Stream Order, Major River). Attribution is an important part of these GIS data layers and continuous efforts to improve the accuracy of the attributes is a strong focus. Current efforts include looking to how technology can help improve the hydrography layers to represent how water flows and is stored across the landscape.
  12. Sean Vaughn is a GIS hydrologist with the Minnesota DNR, Division of Ecological and Water Resources. Sean has been with the Minnesota DNR since 1989. For the last twelve years, he has been the lead GIS specialist and project manager for the DNR Watershed Delineation Project. Sean has many years of experience working with raster data, developing statewide GIS datasets, and creating hydrologically conditioned Digital Elevation Models for Minnesota. He is particularly interested in the development of statewide LiDAR-derived products for utilization in watershed delineation, hydrography identification, and hydrologic analysis.
