geojson-feature-transform

an easy way to convert objects into GeoJSON Feature objects

example

var featureTransform = require('geojson-feature-transform')
var request = require('request')
var JSONStream = require('JSONStream')
var limit = require('limit-stream')
var filter = require('stream-filter')
var through = require('through0')

request('http://bikechattanooga.com/stations/json/')
  .pipe(JSONStream.parse('stationBeanList.*'))
  .pipe(limit(1))
  .pipe(filter(function (x) { return !x.testStation }))
  .pipe(through(featureTransform({x: 'longitude', y: 'latitude'})))
  .on('data', function (x) { console.log(JSON.stringify(x, null, 2))})

usage

geojson-feature-transform is a function which returns a function. Ordinarily you will use this new function lots of times on a collection of many similar objects. After using this transform, you probably want to serialize it with JSON.stringify to get valid GeoJSON.

options

You can specify an options object to override property names:

• x - the property indicating the easting amount, e.g., longitude
• y - the property indicating the northing amount, e.g. latitude
• xy - a property with an array ordered [east, north] (e.g., [lon, lat])
• yx - a property with an array ordered [north, east] (e.g, [lat, lon])
• id - a property with a feature id (primary key)

installation

$ npm install geojson-feature-transform

running the tests

from the project directory
