Expand Collapsed Contours (Maritime Tools)

汇总

Expands (pulls apart) contour lines that are snapped together. This preserves representative depth areas.

用法

注意：

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

  • Collapsed vertices (either within a contour or between contours) are pulled apart where possible by pulling them toward the line made between neighboring vertices. Where the angle is too shallow to allow an offset of the specified expansion distance, that vertex will be removed.

  • The tool modifies the features in the Target Contours parameter.

  • The tool deletes zero-length features.

  • The tool snaps points to 10 times the x,y resolution of the target contours when determining collapsed vertices.

  • Duplicate vertices on contours are removed.

  • The tool messages the feature object ID and collapsed vertices it expands.

  • When a collapsed vertex involves an endpoint of a floating contour, a warning message is generated in the output. Ensure that you review any instances identified.

  • The Expansion Distance parameter is optional. The default is five times S-57 precision (0.0000005).

参数

标注 说明 数据类型

Target Contours

The feature class containing the contours to be expanded.

Feature Layer

Expansion Distance

（可选）

The distance that contours will be expanded based on the coordinate system of the target contours. The default is 5e-7 decimal degrees based on the WGS84 geographic coordinate system.
