使用shapefile库将Geojson转换为shapefile [英] Geojson to shapefile convertion using shapefile library

问题描述

我知道，如果shapefile仅包含多边形，则可以从geojson创建shapefile，但是如果出现MultiPolygon，则会出现以下错误:

I know I can create a shapefile from a geojson if the shapefile only contains Polygons, but in case there is a MultiPolygon I get the following error:

返回[min(x)，min(y)，max(x)，max(y)]

return [min(x), min(y), max(x), max(y)]

TypeError:'<' 'list'和'float'**实例之间不支持**

TypeError: '<' not supported between instances of 'list' and 'float'**

在shapefile.py**

任何有关如何克服此问题的想法都将受到赞赏.

Any ideas of how I can overcome this problem would be appreciated.

谢谢.

    import shapefile

    shape_file_writer = shapefile.Writer(SHAPE_FILE_TYPE)

    #example of field [field, "C", 200, 0]
    shape_file_writer.fields = self.__get_shape_file_fields() 
    for feature in geojson_data["features"]:
        if feature["geometry"]["type"] == "MultiPolygon":
            continue
        else:
            shape_file_writer.poly(parts=feature["geometry"]["coordinates"], shapeType=5)

        shape_file_writer.record(*feature["properties"].values())

推荐答案

经过一番搜索，我发现它是多多边形的

after some search I found that in a multi-polygon

[ 多边形_0， 多边形_1， . . ]

[ polygon_0, polygon_1, . . ]

只有 polygon_0 是实际的多边形，其余的多边形是孔. 就我而言，我根本不需要孔，所以我基本上将多面体转换为面体.

only polygon_0 is the actual polygon and the rest of polygons are holes. In my case I didn't need the holes at all so I converted multi-polygons into polygons basically.
