Team Members

  • Project Manager

  • Kyle Beesley

  • Assistant Project Manager

  • Jeremy Soules

  • Analysts

  • Sean Brugo, Nick Pantuso, Katie Snipes, and Matt Noble



Introduction

  • Our study has identified areas that are ideal for:

      • Landscaping improvement
      • The creation of a campus wide arboretum
      • Increase of native trees
      • Planned areas with pre-placed sitting areas and vegetation




Data

  • Data collection included the acquisition of datasets from secondary sources and the creation of new map layers through primary data collection and digitization.

  • Data processing consisted of the standardization of all layer projections.



DEM

  • DEM

  • -slope

  • -aspect

  • Reclassification











Calculation

  • All three raster layers evaluated

  • Output represents all cells with ratings of two or above

  • New layer was intersected with existing green space layer









Soils

  • Graded on:

  • Drainage

  • Plant sustainability

  • Permeability

  • Water capacity

  • Soil Reaction

  • Organic content







Tree Population Density

  • Density was derived from:









Statisitics

  • Statistical analyses for:

    • Total tree population
    • Individual areas
  • Frequencies included:

    • Species
    • Nativity


Results



Trees

  • Over 3500 trees cataloged

  • Over 63 species

  • 78.6 % of the trees on campus are of native origin

  • 21.4 % are introduced



Planned Areas

  • Based on our analyses we were able to chose the best of these sites.

  • New tree locations

  • Picnic tables

  • New paths

Discussion

  • GIS applications make this kind of planning more efficient and accurate.

  • This project is complimentary to the Campus Master Plan.



Discussion

  • Future research might include:

    • Analysis of underground water, sewage, communications and cooling systems
    • 3-D visualization
    • Higher levels of accuracy
