从HEREAPI接收到利雅得交通的地理数据作为形状点，如何将其加载到地理标准中

Question

我是地理空间数据的新手，我使用HERE API通过使用以下请求url:收集了利雅得的一些交通流量数据

requests.get(f"https://data.traffic.hereapi.com/v7/flow?locationReferencing=shape&in=bbox:46.278534,24.377121,47.040710,25.084355&advancedFeatures=deepCoverage&apiKey={HERE['apikey']}")

他们有三种描述地点的方式，请点击此处：https://developer.here.com/documentation/traffic-api/dev_guide/topics/concepts/location-referencing.html，并且唯一在响应中显示坐标的是Shape Points。我需要带坐标的响应，以便使用地质标准操作和可视化数据，并向每个字符串添加更多数据。然而，反应是这样的：

如果我错了，请纠正我，这是一个混乱的数据，需要手动进行后处理，以便得到地理标准-fiona驱动程序-的支持，这些驱动程序是：

｛'ARCGEN'：'r'，'DXF'：'rw'，'CSV'：'raw'，'OpenFileGDB'：'r'，"ESRIJSON"："r"，"ESRI Shapefile"："raw"，"FlatGeobuf"："rw"，"GeoJSON"："原始"，"GeoJSONSeq"："rw"，"GPKG"："raw"，"GML"："rw"，"OGR_GMT"："rw"，"GPX"："rw"，"GPSTrackMaker"："rw"，"Idrisi"："r"，"MapInfo File"："raw"，"DGN"："raw"，"PCIDSK"："原始"，"OGR_PDS"："r"、"S57"："r"，"SQLite"："raw"，"TopoJSON"："r'"｝

如果你能告诉我一种方法，我可以以任何支持的格式，或者最好是geojson格式获得数据，我真的会很高兴。

还有一个问题，他们的位置是静态的吗？我的意思是，每次我请求交通数据时，我得到的是相同的路段，但交通数据不同，还是路段会根据交通情况而变化？

谢谢！

Answer 1

HERE api以JSON格式返回数据。数据应该根据用例在应用程序级别进行处理。

第二个查询的答案与分段和流量有关。分段不会更改，只会更新交通数据。
