这是以毫秒为单位的UNIX时间戳/纪元。如果你想使用FeatureSet作为一个数据帧，最简单的方法是空间启用数据帧。从arcgis导入GIS。features import FeatureLayer, featurelset from datetime import datetime import json import geopandas as gpd gis = gis () url_2000 = 'https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/Historic_Geomac_Perimeters_All_Years_2000_2018/FeatureServer/0' layer_2000 = FeatureLayer(url_2000) fset_2000 = layer_2000.query() fset_2000。从UTC时间戳到datetime对象的转换是在底层完成的。如果您仍然希望使用来自geopandas模块的GeoDataFrame，则必须编写自己的转换实现。FeatureSet的to_geojson属性将把datetime对象重新转换回UTC时间戳。这看起来有点尴尬。下面的函数将UTC时间戳转换为ISO格式字符串，因为您的代码将GeoJSON重新加载为python对象。此外，to_geojson还将字符串编码为unicode转义字符('\uxxx') -我喜欢我们的德语变音。我建议不要使用to_geojson方法。 The following function directly converts the UTC timestamps into the ISO string format. def convert_timestamps(feature_set: FeatureSet, field_names, use_iso=True): """Converts timestamps (UNIX epoch in [ms]) into datetime objects by modifying the feature set directly.""" for feature in feature_set.features: for attribute_name in feature.attributes: if attribute_name in field_names: if use_iso: feature.attributes[attribute_name] = datetime.utcfromtimestamp(feature.attributes[attribute_name] * 1e-3).isoformat() else: feature.attributes[attribute_name] = datetime.utcfromtimestamp(feature.attributes[attribute_name] * 1e-3) So that, you just need to call it by using: convert_timestamps(fset_2000, ['perimeterdatetime']) gjson_string_2000 = fset_2000.to_geojson gjson_dict_2000 = json.loads(gjson_string_2000) gdf_2000 = gpd.GeoDataFrame.from_features(gjson_dict_2000['features']) The geopandas dataframe contains the correct ISO string. You have to reconvert it into a datetime object, again. This is only needed because of the to_geojson property behavior. Hope it helps. ．.．查看更多
