Surface Spot

Summary

Calculates surface values for each point of a point feature class by interpolating from a raster, TIN, or terrain dataset surface.

Calculated values are added to the input feature class attributes.

Legacy:

This is a deprecated tool that has been superseded by the Add Surface Information tool.

Usage

  • Ensure the input surface and the input feature class have overlapping extents.

  • Use the Z Factor parameter to convert the output field to the desired units.

Syntax

SurfaceSpot_3d (in_surface, in_feature_class, {out_spot_field}, {z_factor}, {method}, {pyramid_level_resolution})
ParameterExplanationData Type
in_surface

The input raster, TIN, or Terrain dataset surface to be used for interpolation.

Terrain Layer; TIN Layer; Raster Layer
in_feature_class

The input point feature class to which the interpolated values will be added.

Feature Layer
out_spot_field
(Optional)

The name of the attribute field to be added to the input feature class. By default, the field name will be Spot.

String
z_factor
(Optional)

The factor multiplied by the surface values to convert them to new values added to the input feature class. Used to convert z units to match x,y units.

Double
method
(Optional)

Algorithm used to calculate surface values.

String
pyramid_level_resolution
(Optional)

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

Double

Code sample

Surface Spot example 1 (Python window)

The following Python Window script demonstrates how to use the Surface Spotfunction in immediate mode.

import arcgisscripting
gp = arcgisscripting.create()

gp.workspace = "C:/data"
gp.SurfaceSpot_3d("elevation_tin", "points.shp", "SPOT", 3.28)
