Objectives

• Use GIS to help improve the delineation of the
  Turkey Creek Watershed.
• Use GIS to estimate landuse changes within the
  watershed over time with historic aerial
  photography.
• Use modeling to fill in gaps between historical
  data and current data.
• Incorporate newly aquired remote sensing data to
  enhance modeling capabilities (Joseph).
