Subdivide a linestring into segments of a specified length

Usage

subdivide_linestring(line, max_length, crs = 5070)

Arguments

line: A linestring or simple feature collection thereof
max_length: The maximum length of each segment. Segments longer than this value will be subdivided; those that are below this threshold will be returned as-is.
crs: The coordinate reference system to which the linestring should be transformed. Default is 5070.

Value

An sf object (simple feature collection) with geometry type LINESTRING. The returned object contains:

row_id: Integer. The row index from the original input linestring, allowing linkage back to the input data.
...: All original attributes from the input line object are preserved and joined back via row_id.
geometry: LINESTRING geometry. Each segment is at most max_length units long (in the CRS units). Segments shorter than max_length in the input are returned unchanged.

The CRS of the output is set to the value specified by the crs parameter (default: EPSG:5070).
