Mapping of streams and rivers over very large areas has always been iterative and expensive. Now Digital Elevation Models (DEM), surfaces and topography derived from LiDAR are revolutionizing the way we represent and analyze surface waters. We will have truly 3-dimensional models and measurements, allowing new analyses of total flow accumulation, flow predictions, regional management decision support and more. This application sharing network can aid in thinking through the changes by sharing ideas and tools.
- Finer-Scale Hydrology Data
- Flow Accumulation
- Flow Predictions
- Enhanced Flowpath Modeling
- Soil Moisture

- Flood Inundation Mapping
- Drainage Areas
- Pennsylvania Water Data Initiative Information - Many practical aspects of modernizing Pennsylvania’s hydrography have already been studied and documented in a series of annual workshops supported by the PA Mapping and Geographic Information Consortium (PaMAGIC)
- Hydro-Modeling with LiDAR Bare-Earth DEM in ArcGIS Tutrorial - US Forest Service
- GIS Topographic Wetness Index (TWI) Exercise Steps - Susquehanna River Basin Commission
