Calculates the aspect (compass direction
of the slope) for each TIN Triangle. Groups the triangles based on their
Aspect category and creates a polygon dataset with 9 Aspect categories.
Inputs:
- A ESRI TIN or PolygonZ TIN
Outputs:
- A polygon feature class
- A new field ET_ACode will be added to the
polygon attribute table. The values in this field will indicate the aspect
groups.
- N - North ( 0 to 22.5 and 337.5 to 360)
- NE - North East (22,5 to 67.5)
- E - East (67.5 to 112.5)
- SE - South East (112.5 to 157.5)
- S - South (67.5 to 112.5)
- SW - South West (202.5 to 247.5)
- W - West (247.5 to 292.5)
- NW - North West (292.5 to 337.5)
- U - Undefined - Slope = 0
