# National Park Trail Data

This is a data extract of National Park Service Trails from their
official sources. They are organized alphabetically by the park name
rather than by state, since some cross state lines, which messes up
the data extracts.

These files have been machine edited by the the 
[trails.py](https://github.com/hotosm/osm-merge/blob/main/osm_merge/utilities/trails.py)
script, which is part of the [OSM
Merge](https://hotosm.github.io/osm-merge/) project. Documentation on
the conversion process is
[here](https://hotosm.github.io/osm-merge/trails/).

# File Types

For now all the files are in a single directory. Later I'll split all
these into tasks for the Tasking Manager.

* *.pbf
  * The OpenStreetMap data for this region
* *_NPS_Trails.geojson
  * Official National Park Service trail data
* *.geojson
  * The region boundary for ogr2ogr or osmium
* *.poly
  * The region boundary for osmconvert

# Bugs

It's entirely likely that when processing this much data, which
depends heavily on a naming convention for all files to be consistent,
obscure problems get lost in the huge output log files from the
automation software. This is all a work in progress, so this wil be
improved over time.
