Install

``
npm install obj2osm
`

Example

` js
var toxml = require('../')
var from2Array = require('from2-array')

var input = require('../test/fixture.json')

var bounds = {
minlat: 38.89958342598271,
maxlat: 38.90385833966776,
minlon: -77.02514648437499,
maxlon: -77.01965332031249
}

from2Array.obj(input)
.pipe(toxml({bounds: bounds}))
.pipe(process.stdout)
`

output:

`
$ node osm.js

`

API

` js
var toxml = require('obj2osm')
`

$3

Where:

* opts.root - Root XML element (default: osm, set to null to output XML with no root)
* opts.generator - Generator attribute for the root element (default: obj2osm)
* opts.bounds - Optional bounds to include at start of XML, either {minlat: , maxlat: , minlon: , maxlon: } or [[minLat, maxLat], [minLon, maxLon]]

Returns a transform object stream that expects a stream of objects matching OSM JSON format as input and produces [osm xml][1] output or [osmChange XML][2] output if input objects have an action property set to one of: create|modify|delete.

Node object format:

* node.type - 'node'
* node.id - id string
* node.version - version string
* node.lat - latitude in degrees
* node.lon - longitude in degrees
* node.tags - Object of tag key-value pairs: {tagKey: 'tagValue', amenity: 'cafe'}

Way object format:

* way.type - 'way'
* way.id - id string
* way.version - version string
* way.nodes - array of node IDs
* way.tags - Object of tag key-value pairs

Relation object format:

* relation.type - relation.type
* relation.id - id string
* relation.version - version string
* relation.members - array of member objects: {type: 'node|way|relation', ref: 'id', role: 'role'}
* relation.tags` - Object of tag key-value pairs
