Simplify Contours

摘要

Defense Mapping production tool that simplifies contours for use in cartographic products. This tool preserves the essential shape of a contour by eliminating extraneous bends.

用法

  • This tool modifies the input contours. You cannot undo this operation.

  • Extraneous bends are composed of redundant vertices. This tool identifies redundant vertices as those that lie within a minimum allowable distance, or tolerance. Tolerance depends upon the Scale parameter.

  • The Scale parameter and tolerance values are designed for use with Defense Mapping cartographic products.

语法

SimplifyContours_defense (Input_Contours, Scale)
参数说明数据类型
Input_Contours

The input contours that are going to be simplified.

Feature Layer
Scale

Scale value used to determine a simplification tolerance. Tolerance specifies a minimum allowable distance between vertices. The tool removes vertices that lie within this tolerance.

  • 1:5000 —Simplification tolerance is 1 meter.
  • 1:7500 —Simplification tolerance is 1 meter.
  • 1:12500 —Simplification tolerance is 1 meter.
  • 1:25000 —Simplification tolerance is 1 meter.
  • 1:50000 —Simplification tolerance is 2 meters. This is the default.
  • 1:100000 —Simplification tolerance is 2 meters.
  • 1:250000 —Simplification tolerance is 3 meters.
  • 1:500000 —Simplification tolerance is 3 meters.
  • 1:1000000 —Simplification tolerance is 3 meters.

SimplifyContours example (Python window)

The following code sample demonstrates how to use the SimplifyContours tool.

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

# variables for tool
inputContours="mgcp.gdb/mgcp/contours"
mapScale="1:12500"

# execute the tool
arcpy.SimplifyContours_defense(inputContours,mapScale)
