Advanced GIS course focusing on raster analysis with particular application to the issues associated with hydrologic analysis. Application and evaluation of algorithms for terrain analysis, watershed characterization, and hydrologic analysis and modeling as implemented in GIS. Digital elevation data sources and error assessment. Approaches to GIS/model integration and application

• Describe and demonstrate how georeferencing, resampling, and vector conversions are handled in a raster GIS data model
• Define, select, and implement raster analysis functions to solve spatial problems
• Define, select, and implement vector analysis operations to solve spatial problems
• Identify and describe characteristics of pertinent geospatial and hydrologic data sources
• Assess the quality of OEM data and evaluate alternatives for improving its utility in hydrologic analysis
• Implement and evaluate alternative approaches for deriving flow networks from elevation data
• Extract representative parameters of watershed hydrologic properties
• Create representative data surfaces by selection and implementation of
  correct interpolation techniques
• Define the TIN data model and its application to hydrologic modeling
• Integrate GIS data with existing hydrologic models (e.g. HEC-HMS)
• Implement and evaluate GIS-based screening/loading models
• Describe approaches to GIS/model integration with examples
• Evaluate sensitivity of models to variability and error in spatial data
