Surface Length (3D Analyst)

Niveau de licence :BasicStandardAdvanced

Récapitulatif

Calculates the surface length for each polyline or polygon feature 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.

Utilisation

Syntaxe

SurfaceLength_3d (in_surface, in_feature_class, {out_length_field}, {sample_distance}, {z_factor}, {method}, {pyramid_level_resolution})
ParamètreExplicationType de données
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
(Facultatif)

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

String
sample_distance
(Facultatif)

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
(Facultatif)

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
(Facultatif)

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

String
pyramid_level_resolution
(Facultatif)

Résolution de taille de fenêtre ou de tolérance z du niveau de pyramide de MNT qui sera utilisée par cet outil. La valeur par défaut est 0 (ou résolution maximale).

Double
