GIS and Solid Waste

1
GIS and Solid Waste

• Site assessment of illegal dump sites using GIS!

2
Site Assessment Form

• The State asks for the following information
• (among other)

• Waste area(s) dimensions
• Soil Type
• Mean annual precipitation
• Is waste area within a flood plain? (Y/N)   
• Slope pitch
• Show detailed site map(s)

3
Waste Area Dimensions

• GPS the outline of the dump.
• The GIS software calculates the surface area,
  perimeter etc.
• Estimate the depth of the dump and calculate the
  rough volume of trash to be removed.
