Convert GTFS data into GeoJSON.
npm install --save gtfs2geojson
gtfs2geojson [--shapes-assume-ordered] [--output output_path] [source_path]
The shapes.txt
and stops.txt
files need to be in the source_path
directory you
specify, or if none is specified the current directory is assumed. If --output
is not
specified the shapes.geojson
and stops.geojson
will be created in the source_path
directory.
If --shapes-assume-ordered
is provided the shapes.txt
is assumed to be ordered by
shape_id
and shape_pt_sequence
as this reduces memory usage and processing time.
However since the GTFS spec doesn't mandate this ordering, the default is to not assume
any ordering.
You may want to set the heap size by invoking with something like node --max_old_space_size=4096 ./gtfs2geojson
(which is 4GB) to prevent errors like FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory
.
lines(gtfs, callback, assumeOrdered)
Parse GTFS shapes.txt
data given as a string or readable stream and invokes callback with
a GeoJSON FeatureCollection of features with LineString geometries. If assumeOrdered
is
true, the GTFS shapes.txt
is assumed to be ordered by shape_id
and shape_pt_sequence
.
However since the GTFS spec doesn't mandate this ordering, the default is false.
stops(gtfs, callback)
Parse GTFS stops.txt
data given as a string or readable stream and invokes callback with
a GeoJSON FeatureCollection of features with Point geometries.
