folium，plugins.TimestampedGeoJson，“时间不可用”

Question

我想使用plugins.TimestampedGeoJson绘制带有时间戳的GeoJSON。

但是我在大叶草地图中的时间栏显示“时间不可用”，并且不起作用。

我找不到我的变量的哪一部分是错误的。

我使用的变量如下。

如何使我的时间栏正常工作？

我试图绘制叶片图。

但是我在地图左下方的时间不起作用。

m = folium.Map([37.5650172,126.8494648], zoom_start = 10)


plugins.TimestampedGeoJson( { 'type': 'FeatureCollection', 'features': features },
                           period='P1D',
                           add_last_point=True,
                           auto_play=False,
                           loop=False,
                           max_speed=1,
                           loop_button=True,
                           date_options='YYYY-MM-DD',

                           duration='P1D' ).add_to(m)

m

Answer 1

我有相同的问题，在我的情况下，以下问题已解决。

这可能是因为您的子字典关键字"time"在每个"coordinates"中没有包含与所用"feature"相同长度的列表。

引用自此discussion：

[...]插件要求每个feature都具有属性"times"，该属性应该是包含以毫秒为单位或ISO的UNIX纪元时间戳的列表格式化时间戳。看到https://python-visualization.github.io/folium/plugins.html#folium.plugins.TimestampedGeoJson
