Simplify Contours (Defense Mapping)

摘要

国防制图 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 国防制图 cartographic products.

• This tool is used by Create and Simplify Contours.

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.

代码实例

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)
