  1. Geography 469: GIS Workshop King County GIS Center – Wetland Delineation “The Wetlanders” Will Kappes, Latif Ba, Fernand Sanchez

  2. Project Goal/Purpose • Determine main components of Wetland Delineation • Define a concise methodology applicable to further research • Generate an Automated System to define areas of interest • Test Automated System to analyze ‘no significance’ wetlands

  3. Project Methods • NTKQ #1 - What elements define a “wetland”? • NTKQ #2 – What type of vegetation is common in wetland areas? • NTKQ #3 – What types of animal species are found in wetland areas? • NTKQ #4 – What class(es) of hydrology is/are found in wetland areas?

  4. Hydrology Metadata

  5. Vegetation Metadata

  6. Animal Species Metadata

  7. Model Builder Routine

  8. Project Results • Generated a concise methodology for implementing wetland delineation practices • Generated a way to create Automated System for Wetland Delineation

  9. Before Analysis

  10. After Analysis

  11. Python Script

  12. Conclusions • Developed methodology for identifying wetland areas • Constructed Model Builder Routine for wetland delineation • Allows client to generate automated system to identify areas of interest • Found that ‘no significant’ wetlands contain threatened plant/animal species

  13. Recommendations • Further research into plant/animal species to determine the size/rating schema for their analysis • Use of Raster data to determine wetland areas facing a higher level of threat (i.e. erosion zones) • Focus on smaller zone oppose to entire county
