例如,我有geojson文件,其功能如下所示。
{“type”:“FeatureCollection”,“working_width”:20,“features”:[{“type”:“Feature”,“geometry”:{“type”:“Point”,“coordinates”:[28.4766,12.5645456 ]}}]
如何将属性添加到此上述文件,如下所示。
{“type”:“FeatureCollection”,“working_width”:20,“features”:[{“type”:“Feature”,“geometry”:{“type”:“Point”,“coordinates”:[28.4766,12.5645456 ]},“properties”:{“fieldID”:“2115145”,“segmentId”:“255c2s4c”,“speed”:21.4586954,“elevation”:52.4586642,“time”:“2018-05”}}]}
数据结构只是一个常规的python字典,因此您可以正常更新它:
>>> geojson
{'type': 'FeatureCollection',
'working_width': 20,
'features': [{'type': 'Feature',
'geometry': {'type': 'Point',
'coordinates': [28.4766, 12.5645456]}}]}
>>> geojson['properties'] = {'fieldID': '2115145',
'segmentId': '255c2s4c',
'speed': 21.4586954,
'elevation': 52.4586642,
'time': '2018-05'}
>>> geojson

'working_width': 20,
'features': [{'type': 'Feature',

'properties': {'fieldID': '2115145',
