如何在 python 中使用 folium 将标记添加到热图？

Question

我正在尝试根据坐标和坐标权重列表制作热图。我现在想将权重值添加到热图集群中，以便我可以看到给定集群区域中有多少人。

我能够使用下面的代码创建热图，但是当我尝试添加plugin.MarkerCluster 部分时，我陷入了困境。如果我将列表 lats_longs 添加到标记集群，它只会给我错误：

    import folium
    from folium.plugins import HeatMap
    from folium import plugins
    map_obj = folium.Map(location=[39.057880, -77.459930], zoom_start=10)
    lats_longs = [
        [38.91072, -77.01666, 1],

    # plugins.MarkerCluster(lats_longs).add_to(map_obj)
    HeatMap(lats_longs).add_to(map_obj)
    map_obj.save("heatmap.html")

Answer 1

你的目的有点不明确。我知道您想要在自己的图层中表示热图和标记簇。我只需要标记簇的纬度和经度以及弹出信息的人数。请参阅此处了解基本标记簇描述。

# plugins.MarkerCluster(lats_longs).add_to(map_obj)
marker_cluster = plugins.MarkerCluster(
    name='heatmap',
    overlay=True,
    control=False,
    icon_create_function=None
)

for k in lats_longs:
    location = k[0], k[1]
    marker = folium.Marker(location=location)
    popup = '{} Persons'.format(k[2])
    folium.Popup(popup, parse_html=True, max_width=100).add_to(marker)
    marker_cluster.add_child(marker)

marker_cluster.add_to(map_obj)
HeatMap(lats_longs).add_to(map_obj)
folium.LayerControl().add_to(map_obj);

#map_obj.save("heatmap.html")
map_obj
