TIN Slope

Summary

Extracts slope information from an input TIN into an output feature class.

Produces a polygon feature class whose polygons are determined by the input TIN's triangle slope values.

Usage

  • Use {class_breaks_table} to constrain slope information into specific break intervals of the output feature class.

  • Use a comma-delimited TXT or DBF file for a class breaks table. The table requires one column for class break values and, optionally, a second column of class codes. Also, the table needs a header row so that the first row of true data is not skipped.

  • Units are only honored when using a class breaks table.

Syntax

TinSlope_3d (in_tin, out_feature_class, {units}, {class_breaks_table}, {slope_field}, {z_factor})
ParameterExplanationData Type
in_tin

The input TIN.

Tin Layer
out_feature_class

The output feature class.

Feature Class
units
(Optional)

The units of measure for the slope values. Units are honored when a class breaks table is used.

String
class_breaks_table
(Optional)

An input table containing the classification breaks that will be used to classify the output feature class.

Table
slope_field
(Optional)

The field containing slope values.

String
z_factor
(Optional)

The factor applied to the slope calculation to convert the TIN's z units to x and y units. By default, the z-factor is 1.

Double
