Как сделать отверстия в многоугольниках, чтобы отображать каждый из них чистыми цветами на карте Google? - PullRequest

У меня есть 4 наложенных многоугольника, и мне нужно иметь несколько чистых цветов, чтобы различать их, например:

Цвета чистые и хорошоотделены!

Мой код:

<!DOCTYPE html>
<html>
  <head>
    <style>

      #map {
        height: 100%;
      }
      /* Optional: Makes the sample page fill the window. */
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }
    </style>
  </head>
  <body>

  <div id="map"></div>

  <script>

     var map;
     var GeoJson;

     function initMap() {

        map = new google.maps.Map(document.getElementById('map'), {
          zoom: 13,
          center: new google.maps.LatLng(-8.044474,-34.884578),
        });
        map.data.addGeoJson(mygeojson);
        map.data.setStyle(function(feature) {
            var pvalue = feature.getProperty('value');

            if (pvalue == 120) {
                color = 'Blue';
            }
            if (pvalue == 240) {
                color = '#ff5050';
            }
            if (pvalue == 480) {
                color = '#ff9933';
            }
            if (pvalue == 600) {
                color = 'yellow';
            }
    return {
      fillColor: color,
      strokeWeight: 1
    }
  });

}

Результат: цвета совмещены, и результат выглядит ужасно:

Любое решение, чтобы просто заполнить видимую часть каждого многоугольника чистыми цветами?

Вам нужно сделать отверстия в полигонах.Есть два варианта:

  1. отредактировать ваш GeoJSON, чтобы добавить следующий наименьший многоугольник в виде отверстия в каждом многоугольнике
  2. написать код для создания многоугольников с отверстиями в них из вашего ввода GeoJSON

отредактировано GeoJSON:
