Sub-pixel Analysis of Invasive Species in Coastal Wetlands

To support this complex surface water assessment, modelling, and analysis project, Allison developed AML, Perl, and Python scripts to synthesize current and future land-use, zoning, parcel, and hydrologic data for hydrologic modelling throughout multiple sub-basins in Snohomish County. Data output from GIS spatial analysis were provided to modellers in an ASCII format that were seamlessly input into an HSPF model. She also developed scripts for managing and processing field-collected survey data, which included quality control methods to provide feedback to surveyors. Allison also supported spatial data development for hydraulic models (HEC-RAS).
