    This module generate Mapbox vector tiles from Elasticsearch.

    Note. This is still under experimental.

    Install package

    npm install @watergis/elastic2mvt

    Usage

    const elastic2mvt = require('@watergis/elastic2mvt');
    
    const es2mvt = new elastic2mvt('localhost:9200');
    const z = 14
    const x = 9524
    const y = 8269
    const indices = [
      {
        // Please specify target Elasticsearch index name
        name : 'water_connection',
        // specify the size of searching result. Default is 10000.
        size: 10000,
        // if you don't specify, 'geom' will be used as default column name
        geometry: 'geom',
        //Please specify your query for Elasticsearch. 
        // if it is not defined, {"match_all": {}} will be used as default.
        query: { 
          "term": {
            "connection_type": "Water Kiosk"
          }
        }
      },
      {
        name : 'pipeline',
        geometry: 'geom'
      },
      {
        name : 'wss',
        geometry: 'geom'
      }
    ]
    const buffer = await es2mvt.generate(z,x,y,indices)
    console.log(buffer)

    Preparation

    Before using this module to convert from Elasticsearch to Mapbox binary vector tile, please insert your GIS data by using ogr2ogr. This module adopted flat structure of Elasticsearch documents. It maybe does not work for other mapping types of Elastic documents which were inserted by other tools except ogr2ogr.

    The following command is an example to insert from PostGIS.

    ogr2ogr -f "Elasticsearch" -lco NOT_ANALYZED_FIELDS={ALL} -lco INDEX_NAME=water_connection -lco OVERWRITE=YES http://localhost:9200 "PG:host='localhost' port=5432 user='postgres' dbname='rwss_assets' password='password'" water_connection -skipfailures
