我有一本真正的geojson字典:
points = {
'crs': {'properties': {'name': 'urn:ogc:def:crs:OGC:1.3:CRS84'}, 'type': 'name'},
'features': [
{'geometry': {
'coordinates':[[[-3.693162104185235, 40.40734504903418],
[-3.69320229317164, 40.40719570724241],
[-3.693227952841606, 40.40698546120488],
[-3.693677594635894, 40.40712700492216]]],
'type': 'Polygon'},
'properties': {
'name': 'place1',
'temp': 28},
'type': 'Feature'
},
{'geometry': {
'coordinates': [[[-3.703886381691941, 40.405197271972035],
[-3.702972834622821, 40.40506272989243],
[-3.702552994966045, 40.40506798079752],
[-3.700985024825222, 40.405500820623814]]],
'type': 'Polygon'},
'properties': {
'name': 'place2',
'temp': 27},
'type': 'Feature'
},
{'geometry': {
'coordinates': [[[-3.703886381691941, 40.405197271972035],
[-3.702972834622821, 40.40506272989243],
[-3.702552994966045, 40.40506798079752],
[-3.700985024825222, 40.405500820623814]]],
'type': 'Polygon'},
'properties': {
'name': 'place',
'temp': 25},
'type': 'Feature'
}
],
'type': u'FeatureCollection'
}
我想过滤它以仅停留在具有特定温度的地方,例如,超过25摄氏度。
我设法这样做了:
dict(crs = points["crs"],
features = [i for i in points["features"] if i["properties"]["temp"] > 25],
type = points["type"])
但我想知道是否有任何方法可以更直接地使用字典理解。
非常感谢。
