simplify_shapes

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

Convert general transit feed specification (GTFS) data to global positioning system (GPS) records in 'data.table' format. It also has some functions to subset GTFS data in time and space and to convert both representations to simple feature format.

simplify_shapes function

<dl><dt>gtfs_data</dt>
<dd>A list of data.tables read using gtfs2gps::read_gtfs().</dd>
<dt>tol</dt>
<dd>Numerical tolerance value to be used by the Douglas-Peucker algorithm.
