Create Contours (Defense Mapping)

Niveau de licence :BasicStandardAdvanced

Récapitulatif

Esri Defense Mapping cartographic production tool that creates and smooths contours from an input raster.

This tool uses the following process to generate contours:

  1. Creates contours by executing the ArcGIS Spatial Analyst Contour tool.
  2. Smooths contours by applying a Cartographie militaire-specific algorithm.
  3. Calculates contour fields that pertain to Cartographie militaire data models.

Syntaxe

CreateContours_defense (Input_Raster, Map_Scale, Base_Contour, Contour_Interval, Index_Interval, Include_Zero_Contour, Out_Contour_Features, Contour_Subtype)
ParamètreExplicationType de données
Input_Raster
[Input_Raster,...]

A list of rasters from which contours will be created.

Raster Layer
Map_Scale

The scale at which the cartographic product is going to be printed. The tool optimizes cartographic display by setting a minimum feature length based on this scale.

  • 1:5000Contour printing is optimized for scale 1:5000.
  • 1:7500Contour printing is optimized for scale 1:7500.
  • 1:12500Contour printing is optimized for scale 1:12500.
  • 1:25000Contour printing is optimized for scale 1:25000.
  • 1:50000Contour printing is optimized for scale 1:50000. This is the default.
  • 1:100000Contour printing is optimized for scale 1:100000.
  • 1:250000Contour printing is optimized for scale 1:250000.
  • 1:500000Contour printing is optimized for scale 1:500000.
  • 1:1000000Contour printing is optimized for scale 1:1000000.
String
Base_Contour

Base contour value. Contours are generated above and below this value to cover the entire value range of the input raster. Setting this value to 5 and the contour interval to 10 will produce contour lines at 5, 15, 25, -5, -15, and so forth. The default is zero.

Double
Contour_Interval

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

Double
Index_Interval

Indicates the index contour interval.

Double
Include_Zero_Contour

Indicates if the tool will create a zero contour. A zero contour represents sea level. Zero contours, when generated along a coastline, may be created inside a water body. Specify ZERO_CONTOUR if you will generate contours on land areas that are at or below sea level.

  • NO_ZERO_CONTOURDo not include a zero contour. This is the default.
  • ZERO_CONTOURInclude a zero contour.
Boolean
Out_Contour_Features

An existing Cartographie militaire feature class. The tool appends contours to this feature class.

Feature Layer
Contour_Subtype

A subtype in Out_Contour_Features to which contours will be written.

String

Exemple de code

CreateContours example (Python window)

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

# set gp environment
arcpy.env.workspace="C:/data"

# variables for tool
rasters="elevation.tif"
mapScale="1:12500"
baseContour=0
contourInterval=10
indexInterval="ZERO_CONTOUR"

# output feature class must exist
outContours="mgcp.gdb/mgcp/contours"
contourSubtype="FCSubtype"

# execute the tool
arcpy.CreateContours_defense(rasters,mapScale,baseContour,contourInterval,indexInterval,outContours,contourSubtype)
