Installing
npm install query-fis-broker-wfs
Usage
const getFeatures = require('query-fis-broker-wfs/get-features')
const endpoint = 'https://fbinter.stadt-berlin.de/fb/wfs/geometry/senstadt/re_postleit'
const layer = 'fis:re_postleit'
const bbox = [387000, 5812000, 386000, 5813000]
getFeatures(endpoint, layer, {bbox})
.on('data', console.log)
.on('error', console.error)
It will return data in the xml-reader
shape:
{
type: 'element',
name: 'fis:re_postleit',
parent: {
type: 'element',
name: 'wfs:member',
attributes: {}
},
attributes: {
'gml:id': 're_postleit.12165'
},
children: [
{
type: 'element',

attributes: {},
children: [ {
type: 'element',
name: 'gml:Polygon',
attributes: {
'gml:id': 'P1'
},
children: [ /* GML data */ ]
} ],
},
// …
