LineCloser

Converts a linear feature to an area by connecting the end point to the start point.

Jump to Configuration

Typical Uses

  • Creating areas from unclosed linear features

How does it work?

The LineCloser receives linear features and connects their end points to their start points, creating closed polygons. An additional vertex is added at the position of the start point.

Z coordinates are supported. Where the first and last points of the input feature have the same x and y coordinates but differing z values, the Connect Z Mode parameter determines how the points are handled.

No checking is performed on the output geometry, and self-intersecting polygons can be created.

Non-linear features are passed through unchanged.

Examples

Usage Notes

  • The AreaBuilder can also close linear geometry into areas, but moves the end vertex rather than adding an additional vertex to close.

  • Use the GeometryValidator to check for self-intersecting geometry after using the LineCloser.

Creating and Modifying Linear Features

These transformers work with lines in a variety of ways.
