The tree height field values are estimated vegetation heights by vegetation class or code alternately a standard zone distance field value can be assigned to indicate a default zone width that the tool will use instead of calculating zone width from tree height Each feature should be assigned either a height or a standard distance value a value of 1 signifies which field value should be ignored A minimum zone width of 1 m should be applied for barren classes and open water should be assigned a zone width of 0 Adding height and distance fields can be accomplished by first creating a table of heights and or standard distances by tree species class or code then joining the table to the vegetation feature class A sample tree height table based on CALVEG classifications is provided in the RipZET download but the same approach can be applied for any classification system as long as a unique code exists for joining the vegetation features HyCon Module Data Requirements All datasets should be saved with a consistent spatial reference in a file geodatabase 1 Required format point feature class 2 This dataset should contain a single point representing the along stream midpoint of the reach Watershed Area s 1 Required format polygon feature class i Si Beal f I a a ms sail II INA LVVOUI IS 1 Required format line feature class 2 Stream segment data in the area of interest may need to be edited to align approximately with
