Преобразование строки в файл многоугольника или geojson в Geopandas ⇐ Python

[Anonymous]

У меня есть следующий файл САПР в формате dxf, который отображается в autocad следующим образом:

Я конвертирую его в файл формата geojson с именем test.geojson с помощью GDAL org2org, но все в тип: LineString

{
"type": "FeatureCollection",
"name": "entities",
"features": [
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 30.0, 0.0 ], [ 30.0, 9.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 16.0, 47.0 ], [ 16.0, 34.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 16.0, 13.0 ], [ 16.0, 0.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 0.0, 31.0 ], [ 9.0, 31.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 30.0, 31.0 ], [ 39.0, 31.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 0.0, 23.0 ], [ 9.0, 23.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 30.0, 23.0 ], [ 39.0, 23.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 0.0, 16.0 ], [ 9.0, 16.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 30.0, 16.0 ], [ 39.0, 16.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 0.0, 0.0 ], [ 39.0, 0.0 ], [ 39.0, 47.0 ], [ 0.0, 47.0 ], [ 0.0, 0.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 9.0, 38.0 ], [ 11.0, 38.0 ], [ 11.0, 34.0 ], [ 28.0, 34.0 ], [ 28.0, 38.0 ], [ 30.0, 38.0 ], [ 30.0, 9.0 ], [ 28.0, 9.0 ], [ 28.0, 13.0 ], [ 11.0, 13.0 ], [ 11.0, 9.0 ], [ 9.0, 9.0 ], [ 9.0, 38.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 11.0, 32.0 ], [ 17.0, 32.0 ], [ 17.0, 15.0 ], [ 11.0, 15.0 ], [ 11.0, 32.0 ] ] } },
{ "type": "Feature", "properties": { "Layer": "0" }, "geometry": { "type": "LineString", "coordinates": [ [ 20.0, 32.0 ], [ 28.0, 32.0 ], [ 28.0, 15.0 ], [ 20.0, 15.0 ], [ 20.0, 32.0 ] ] } }
]
}


Я хочу преобразовать его в тип: многоугольник с отображением, как показано на следующем изображении:


Как я могу сделать это в Geopandas? Спасибо.

Кстати, я прочитал файл test.geojson, он выглядит так:

import geopandas as gpd
df = gpd.read_file("test.geojson")
df.head(5)


Вывод:

Layer SubClasses EntityHandle geometry
