将GeoJSON特性集合转换为GeoJSON列表
将GeoJSON特性集合转换为GeoJSON列表
提问于 2022-05-22 11:27:19
我已经使用geopandas库创建了一个观测功能集合。我想将这些特性传递到paquo库中，特别是传递给load_geojson函数。文档说这需要一个geojson列表。如何使用Python将我的特性集合转换为geojson列表？
我正在使用的geojson特性集合的一个小示例(或更小)。这是存储在一个名为detections.geojson的文件中的currenlty，所以我想加载它，将它转换成一个json列表，然后将它传递给pass函数。

paquo.hierarchy.QuPathPathObjectHierarchy.load_geojson函数需要一个字典列表，每个字典都必须有一个“几何学”键，其中对应的值可由shapely.geometry.shape解析。因此，以下几点应能奏效：
