Question

我试图读取Flickr发布的一组shapefile，它们位于here。我尝试使用geojson聚焦库和常规JSON库导入它，但是我得到了同样的错误：

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 16 column 4 (char 765)

我认为文件中的JSON有问题。这是我在pygeoj

中使用的命令

pygeoj.load(filepath='/flickr_shapefiles/flickr_shapes_localities.geojson')

这里是其中一个文件的前几行

Answer 1

上面的评论是正确的。我必须在文件中读取，删除最后的逗号并创建一个新的json文件，以便geojson正确读取它。

以下是我用于此的代码：

with open('flickr_shapefiles/flickr_shapes_regions.geojson', 'r') as file:
    data = ""
    for line in file.readlines():
        data += line.replace(" ", "").replace("\t", "").replace("\n", "")

new_data = data.replace(",}", "}")

this = json.loads(new_data)

with open('/flickr_shapefiles/flickr_shapes_regions_fix.geojson', 'w') as outfile:
    json.dump(this, outfile)

Flickr GeoJSON无法加载Python
