Bands From Features (Production Mapping)

许可等级:BasicStandardAdvanced

摘要

Converts point, multipoint, polyline, or polygon elevation features within an area of interest (AOI) into polygon band features. Output band size is determined by defining ranges from an input attribute, such as elevation, in the input feature class or layer. A polygon feature class or feature layer defines the AOI.

参数说明数据类型
in_elevation_features
[[Feature layer, Field, Linear Unit],...]

The point, multipoint, polyline, or polygon feature layers or feature classes, their attribute fields (value fields) that contain elevation or isoline data, and distance units of those value fields.

Value Table
in_bands_units

Output band distance units.

  • METERSOutput distance unit is meters. This is the default.
  • FEETOutput distance unit is feet.
String
out_bands_featureclass

The output feature class that contains the bands created by the tool.

Feature Class
in_ranges_as_percent

Specifies if the tool interprets range values as values or percentiles.

  • ABSOLUTE_VALUEInterpret range values as values. This is the default.
  • PERCENTILE_VALUEInterpret range values as percentiles.
Boolean
in_bands_ranges
[[from_value, to_value, range_name],...]

The from-to range values for the bands to be created. The list should contain space-delimited strings with a from value, to value, and a name for the range. A range from 100 to 200 feet could look like this: 100 200 low_elev.

Value Table
in_aoi_features
(可选)

Polygon feature layer or feature class defining the area of interest.

Feature Layer
in_aoi_field
(可选)

Field containing a unique identifier for each map sheet.

Field
in_aoi_buffer
(可选)

A buffer to apply to input area of interest features. The buffer expands the AOI Feature Class geometry to include features in the Contour Feature Class that lie beyond the boundary of an AOI. This can improve the accuracy of the banding calculation used to generate the elevation tint polygons.

Linear Unit
in_exclusion_features
[in_exclusion_features,...]
(可选)

Polygon feature layers or feature classes used to exclude areas from processing where exclusion and AOI features overlap.

Feature Layer
in_rounding_option
(可选)

Specifies whether input values round up, down, or interpolate within their range. Interpolate is the default option.

  • InterpolateEstimate values based on surrounding values. This is the default.
  • Round upRound elevation or isoline values up.
  • Round downRound elevation values down.
String
in_iterations_count
(可选)

Number of times, from 1 to 5, the tool will run on a feature to narrow down the interpolated value. The default is 2.

注注:

This option is only available if PERCENTILE_VALUE is set for in_ranges_as_percent and in_rounding_option is set to Interpolate.

String
in_tolerance
(可选)
注注:

This option is only available if PERCENTILE_VALUE is set for in_ranges_as_percent and in_rounding_option is set to Interpolate.

Otherwise, tolerance is computed from the high and low value in the value field.

Double
in_refine_elevation_model
(可选)

Specifies if the tool will run a triangulation algorithm that refines the tool's processing elevation model.

  • REFINE_ELEVATION_MODELRun refine triangulation processing. This is the default.
  • NO_REFINE_ELEVATION_MODELDo not run refine triangulation processing.
Boolean
out_triangulation_featureclass
(可选)

The triangulated feature class used to generate bands from features.

Feature Class
out_interpolated_isolines_featureclass
(可选)

Polyline feature class interpolated from Input Elevation Features.

Feature Class
out_topological_errors_featureclass
(可选)

Point feature class that contains topological error features produced during processing. Types of errors include:

  • Dangles: A line endpoint unconnected to any other feature.
  • Different elevations at a point: Multiple points with different elevations at the same location.
  • Intersections: Isoline intersection with equal elevation.
  • Intersection and Elevation: Both intersection and different elevation errors.

代码实例

BandsFromFeatures example (Python window)

The following Python window script demonstrates how to use the BandsFromFeatures tool.

import arcpy

# set gp environment
arcpy.env.workspace="c:/data/Austin.gdb"
arcpy.env.addOutputsToMap = True
arcpy.env.overwriteOutput = True

# path to the contours feature class
elevations = "TopographicMap/ContourL Elevation Meters"

# output bands feature class
bands = "ElevationBands"

# Range list used to define the bands
rangeList = "0 500 0-500;501 600 500-600;601 700 600-700;800 2000 800-2000"

# execute the tool
arcpy.BandsFromFeatures_production(elevations,"Meters",bands,"ABSOLUTE_VALUE",rangeList)
