Hello list,
I'm needing help writing expressions to classify forest stands by age. My shapefile includes a data item named "AGE2000" which is a numeric item representing the age fo the stand. How do I need to set up classes if I want to represent the data in 10-year age classes. Values of "AGE2000" range from 0 to 74. Right now I have:
LAYER
NAME standage
TYPE polygon
STATUS off
DATA stand110
CLASSITEM "AGE2000"
CLASS
NAME "0 - 9"
EXPRESSION "???"
SYMBOL 0
OUTLINECOLOR 0
COLOR 50 255 50
END
CLASS
NAME "10 - 19"
EXPRESSION "???"
