osmtogeojson
|
||||
============
|
||||
|
||||
Converts [OSM](http://openstreetmap.org) [data](http://wiki.openstreetmap.org/wiki/OSM_XML) to [GeoJSON](http://www.geojson.org/). Try the [demo](http://tyrasd.github.io/osmtogeojson/)!
|
||||
|
||||
* stable
|
||||
* real OSM [polygon detection](https://wiki.openstreetmap.org/wiki/Overpass_turbo/Polygon_Features)
|
||||
* proper OSM multipolygon support
|
||||
* full support for extended Overpass API [geometry modes](http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Print_.28out.29)
|
||||
* well [tested](https://github.com/tyrasd/osmtogeojson/tree/gh-pages/test/) and proven
|
||||
* fast
|
||||
|
||||
This code is used in and maintained by the [overpass turbo](http://github.com/tyrasd/overpass-ide) project.

|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
### command line tool
|
||||
|
||||
Installation:
|
||||
|
||||
$ npm install -g osmtogeojson
|
||||
|
||||
Usage:
|
||||
|
||||
$ osmtogeojson file.osm > file.geojson
|
||||
|
||||
Supported command line options are shown with:
|
||||
|
||||
$ osmtogeojson --help
|
||||
|
||||
When working with extra large data files (≳ 100 MB) it is recommended to run the programm with a little extra memory to avoid *process out of memory* errors. The easiest way to do this is by running the command as `node <path-to-osmtogeojson>` and setting the `--max_old_space_size=…` parameter to the available memory size in MB (osmtogeojson typically needs about 4-5 times the input data size):
|
||||
|
||||
$ node --max_old_space_size=8192 `which osmtogeojson` large.osm > large.geojson
|
||||
|
||||
### nodejs library
|
||||
|
||||
Installation:
|
||||
|
||||
$ npm install osmtogeojson
|
||||
|
||||
Usage:
|
||||
|
||||
var osmtogeojson = require('osmtogeojson');
|
||||
osmtogeojson(osm_data);
|
||||
|
||||
### browser library
|
||||
|
||||
<script src='osmtogeojson.js'></script>
|
||||
|
||||
osmtogeojson(osm_data);
|
||||
|
||||
API
|
||||
---
|
||||
|
||||
### `osmtogeojson( data, options )`
|
||||
|
||||
Converts OSM data into GeoJSON.
|
||||
|
||||
* `data`: the OSM data. Either as a XML DOM or in [OSM JSON](http://overpass-api.de/output_formats.html#json).
|
||||
* `options`: optional. The following options can be used:
|
||||
* `flatProperties`: If true, the resulting GeoJSON feature's properties will be a simple key-value list instead of a structured json object (with separate tags and metadata). default: false
|
||||
* `uninterestingTags`: Either a [blacklist](https://github.com/tyrasd/osmtogeojson/blob/2.0.0/index.js#L14-L24) of tag keys or a callback function. Will be used to decide if a feature is *interesting* enough for its own GeoJSON feature.
|
||||
* `polygonFeatures`: Either a [json object](https://github.com/tyrasd/osmtogeojson/blob/2.0.0/polygon_features.json) or callback function that is used to determine if a closed way should be treated as a Polygon or LineString. [read more](https://wiki.openstreetmap.org/wiki/Overpass_turbo/Polygon_Features)
|
||||
|
||||
The result is a javascript object of GeoJSON data:
|
||||
|
||||
GeoJSON
|
||||
-------
|
||||
|
||||
The GeoJSON produced by this library will include exactly one GeoJSON-feature for each of the following OSM objects (that is everything that is also visible in overpass turbo's map view):
|
||||
|
||||
* all unconnected or [*interesting*](#api) tagged nodes (POIs)
|
||||
* all ways (except [*uninteresting*](#api) multipolygon outlines)
|
||||
* all multipolygons (simple multipolygons with exactly one closed outer way are present via their outer way)
|
||||
|
||||
All data is given as a FeatureCollection. Each Feature in the collection has an `id` property that is formed from the type and id of the original OSM object (e.g. `node/123`) and has the member `properties` containing the following data:
|
||||
|
||||
* `type`: the OSM data type
|
||||
* `id`: the OSM id
|
||||
* `tags`: a collection of all tags
|
||||
* `meta`: metainformaton about the feature (e.g. version, timestamp, user, etc.)
|
||||
* `relations`: an array of relations the feature is member of. Each relation is encoded as an object literal containing the following properties: `role` (membership role), `rel` (the relation's id) and `reltags` (contains all tags of the relation)
|
||||
* `tainted`: this flag is set when the feature's geometry is incomplete (e.g. missing nodes of a way or missing ways of a multipolygon)
|
||||
|
||||
If the [option](#api) `flatProperties` is set to true, the `properties` object will not contain any nested object literals, but directly provide a concise id, meta data and the tags of the respective OSM object.
