Converts an ESRI TIN to a
PolygonZ TIN feature class. Calculates several 3D characteristics for each
triangle and stores them in the attribute table
Inputs:
- An ESRI TIN
- Options for calculating Z characteristics of
the triangles
Outputs:
- New polygon Z feature class.
- The PolygonZ TIN will be analysed and several
characteristics will be added in the attribute table for each triangle.
- ET_ElMin - minimum elevation values for
each triangle
- ET_ElMax - maximum elevation values for
each triangle
- ET_ElMean - mean elevation values for each
triangle
- ET_Slope_D - the slope (maximum rate of
elevation change) of each triangle in Degrees (from 0 to 90)
- ET_Sope_P - the slope (maximum rate of
elevation change) of each triangle in percents (from 0 to 100%)
- ET_Aspect - the aspect - compass direction
of the slope (horizontal direction in which a slope faces) - 0 is North, 90 degrees - East, 180 degrees - South, 270 -
West of each triangle
- ET_ACode - aspect categories
- 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
- ET_AreaZ - the 3D area of each triangle
- ET_Hill - the brightness of each triangle
based on a light source location
