Split linestrings into equal segments

Divides each linestring into segment_count segments of equal length, returning a multilinestring. Returns NA if segmentation fails. ga_line_segmentize_haversine() uses the Haversine formula for geographic coordinates; ga_line_segmentize() uses planar Euclidean distance.

Usage

ga_line_segmentize(geometry, segment_count)

ga_line_segmentize_haversine(geometry, segment_count)

Arguments

geometry

a GeoArrow linestring array

segment_count

the number of segments to split each linestring into; must be greater than 0

Value

a GeoArrow multilinestring array
