Identify Contours (Topographic Production)

ArcGIS Pro 3.4 | | 帮助归档

摘要

Identifies types of contours and applies hypsographic codes to input features.

使用情况

  • This tool processes each input contour and identifies the contour type. It uses the underlying raster and contour features to identify the type of contour. It then updates the contour code field with the appropriate domain code.

  • This tool identifies the following types of contours:

    • Index
    • Intermediate
    • Depression index
    • Depression intermediate

  • 警告:

    此工具会修改输入数据。 有关详细信息以及避免数据被意外更改的策略,请参阅修改或更新输入数据的工具

  • If more than one input raster is used, all input rasters must have the same cell size, band count, and pixel type. All input rasters should also use the same elevation units (meters or feet).

  • If the Number of Depression Contours to Identify parameter value is negative or zero, the tool will not run.

参数

标注说明数据类型
Input Contours

The input contours that will be updated with the specified contour codes.

Feature Layer
Input Rasters

The rasters that will be used to derive elevations of points inside contours to correctly identify the types of contours.

Raster Layer; Mosaic Layer
Contour Height Field

The field in the input contour feature class that contains elevation values. This field type must be numeric.

Field
Contour Code Field

The field in the input contour feature class that will be updated with the appropriate domain code.

Field
Contour Index Interval
(可选)

The interval, or distance, between index contour lines. The default is 100.

Long
Index Code
(可选)

The value that will be used to populate the Contour Code Field parameter value when index contours are identified. The default is 1.

String
Intermediate Code
(可选)

The value that will be used to populate the Contour Code Field parameter value when intermediate contours are identified. The default is 2.

String
Depression Code
(可选)

The value that will be used to populate the Contour Code Field parameter value when depression contours are identified. The default is 5.

String
Depression Intermediate Code
(可选)

The value that will be used to populate the Contour Code Field parameter value when depression intermediate contours are identified. The default is 6.

String
Number of Depression Contours to Identify
(可选)

The number of contours in a depression that will be coded as depressions. The value provided must be greater than zero. If no value is provided, all of the contours in the depression will be coded as depressions.

Long
Area of Interest
(可选)

The layer that defines the processing extent. The layer must have only one selected feature.

Feature Layer
Z Factor
(可选)

The conversion factor that will be used to convert the contour elevation value unit of measurement to match the raster's unit of measurement. The default is 1.

For example, if the elevation values in the input raster are in meters but the contours are in feet, set the z-factor to 3.28084 (1 meter = 3.28084 feet).

Double
Supplemental Contours
(可选)

Specifies the interval at which supplemental contours will be created. Supplemental contours are used when the terrain change is not large enough to be depicted with consistent contour intervals.

  • NoneNo supplemental contours will be created. This is the default.
  • Half AuxiliarySupplemental contours will be created at one-half the contour interval.
  • Quarter AuxiliarySupplemental contours will be created at one-quarter the contour interval.
String
Half Auxiliary Code
(可选)

The code value that will be stored in the Contour Code Field parameter value when a half auxiliary contour is identified. The default code will be 3 if the HQC field exists in the input contour feature class.

String
Quarter Auxiliary Code
(可选)

The code value that will be stored in the Contour Code Field parameter value when a quarter auxiliary contour is identified. The default code will be 14 if the HQC field exists in the input contour feature class.

String
Depression Auxiliary Code
(可选)

The code value that will be stored in the Contour Code Field parameter value when a depression auxiliary contour is identified. The default code will be 22 if the HQC field exists in the input contour feature class.

String
Contour Interval
(可选)

The interval, or distance, between contour lines. This can be any positive number. The default is 20.

Double
Base Contour
(可选)

The value that contours will be generated above and below to cover the entire value range of the input raster. The default is 0.

Double
