TIN Slope (3D Analyst)
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.
Legacy:This is a deprecated tool. To learn more about how this tool works click here to view archived documentation. This functionality has been added to the Surface Slope tool.
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. An example is illustrated in the following link: Learn more about how TIN Slope (3D Analyst) works.
-
Units are only honored when using a class breaks table.
Syntax
| Parameter | Explanation | Data 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 |
Code Sample
The following Python Window script demonstrates how to use the TIN Slope function in immediate mode.
import arcgisscripting
gp = arcgisscripting.create()
gp.CheckOutExtension("3D")
gp.workspace = "C:/data"
gp.TinSlope_3d("tin", "slope.shp")
