ToolBox implementation
(Go to TOP)

Calculates several characteristics (Slope, Aspect, Min & Max Elevation, Mean Elevation, Hillshade values) for each triangle of a TIN (polygonZ)

Command line syntax

ET_GPAnalyzeTIN <input_dataset> <out_feature_class> <Light_Azimuth><Light_Altitude>


Expression Explanation
<input_dataset> A  PolygonZ feature class or feature layer. 
<out_feature class> A String - the full name of the output feature class (A feature class with the same full name should not exist)
{Light_Azimuth} A Double representing the azimuth angle of the light source. The azimuth is expressed in positive degrees from 0 to 360, measured clockwise from the north. The default is 315 degrees.
{Light_Altitude} A Double representing the altitude angle of the light source above the horizon. The altitude is expressed in positive degrees, with 0 degrees at the horizon and 90 degrees directly overhead. The default is 45 degrees.

Scripting syntax

ET_GPAnalyzeTIN (input_dataset out_feature_class Light_Azimuth Light_Altitude)

<> - required parameter
{} - optional parameter
