neighborhood-outlines

Introduction

Takes GeoJSON data for neighborhood outlines, and formats it so that we can use them on our maps.

Each main city (Berlin, Leipzig, Potdam) has a folder containing folders for each of the main districts (Bezirke). Inside each of these folders is a single JSON file for each of the neighborhoods (Ortsteile). You can choose to pull in an entire city with all the districts, or import each one as needed. You can also pull in the entire city with all the nieghborhoods, or import each one as needed.

// importing a single Bezirk for a city
import { bezirkLichtenberg } from 'neighborhoods-outlines/berlin';

// importing ALL the Bezirke for a city
import { berlin, leipzig } from 'neighborhood-outlines';
or
import { allBezirks } from 'neighborhood-outlines/berlin;

// importing a selection of Ortsteile for a city
import { moabit, wedding, schoeneberg } from 'neighborhood-outlines/berlin';

// importing ALL the Ortsteile for a city
import { berlinNeighborhoods, leipzigNeighborhoods } from 'neighborhood-outlines';
or
import { allNeighborhoods } from 'neighborhood-outlines/berlin;

Example Usage

import { berlin } from 'neighborhood-outlines';

inside of GoogleMapReact onGoogleApiLoaded handler:

const gMap = map.map_;
const shapes = berlin.reduce((results, nextNeighborhood) => {
  if (Array.isArray(nextNeighborhood.coordinates[0])) {
    nextNeighborhood.coordinates.forEach((coords) => {
      const shape = new google.maps.Polygon({
        paths: coords,
        strokeColor: '#FF0000',
        strokeOpacity: 0.8,
        strokeWeight: 2,
        fillColor: '#FF0000',
        fillOpacity: 0.35,
        zIndex: 1000,
      });

      results.push(shape);
    });
  } else {
    const shape = new google.maps.Polygon({
      paths: nextNeighborhood.coordinates,
      strokeColor: '#FF0000',
      strokeOpacity: 0.8,
      strokeWeight: 2,
      fillColor: '#FF0000',
      fillOpacity: 0.35,
      zIndex: 1000,
    });

    results.push(shape);
  }
  return results;
}, []);

shapes.forEach(shape => shape.setMap(gMap));
