simplify_shapes {gtfs2gps}

Simplify shapes of a GTFS file

Description

Remove points from the shapes of a GTFS file in order to reduce its size. It uses Douglas-Peucker algorithm internally.

Usage

simplify_shapes(gtfs_data, tol = 0)

Arguments

gtfs_data

A list of data.tables read using gtfs2gps::read_gtfs().

tol

Numerical tolerance value to be used by the Douglas-Peucker algorithm. The default value is 0, which means that no data will be lost.

Value

A GTFS data whose shapes is a subset of the input data.
