Surface Length (3D 分析)

摘要

This tool calculates the surface length for each polyline or polygon in a feature class based on a raster, triangulated irregular network (TIN), or terrain dataset surface.

The surface length information is stored as an attribute of the input feature class.

用法

语法

SurfaceLength_3d (in_surface, in_feature_class, {out_length_field}, {sample_distance}, {z_factor}, {method}, {pyramid_level_resolution})
参数说明数据类型
in_surface

The input raster, TIN, or terrain dataset whose values will be used for interpolation.

TIN layer; raster layer; terrain lLayer
in_feature_class

The input polygon or polyline feature class.

Feature layer
out_length_field
(可选)

The name of the attribute field to contain the surface length.

String
sample_distance
(可选)

The surface spacing at which the length is calculated. By default, the sampling distance is the natural densification of a TIN or the cell size of a raster.

Double
z_factor
(可选)

The factor multiplied by input surface values to store new values in the length field. The Z factor is used to convert z-units to match x,y units.

Double
method
(可选)

The interpolation method. For raster surfaces, the only option is BILINEAR. Select LINEAR or NATURAL_NEIGHBORS.

String
pyramid_level_resolution
(可选)

The resolution of the terrain dataset pyramid level to use for geoprocessing. The default is 0, full resolution.

Double

代码示例

Surface Length Example 1 (Python window)

The following Python Window script demonstrates how to use the Near 3D function in immediate mode.

import arcgisscripting
gp = arcgisscripting.create()

gp.CheckOutExtension("3D")
gp.workspace = "C:/data"
gp.SurfaceLength_3d("elevation_tin", "lines.shp", "Length3D")
