我想将此 geojson 导入到我在 Google 地球引擎上的代码编辑器中。查看文档（资产管理器），GEE 接受资产作为光栅图像、形状文件（.shp、shx、dbf、prj）。

另外，我发现通过融合表导入特征集合，但它仍然需要 shapefile。

我找到了一些 geojson 到 shapefile 转换器，但我需要一种方法将我的 geojson 直接导入 GEE 上的功能集合。那可能吗？

您还可以将 GeoJSON 几何对象直接导入 JavaScript 或 Python API，例如，使用 MultiPolygon 的以下格式：

feature_geometry = {
  "type": "MultiPolygon",
  'coordinates": [
    [
      [
        [-120, 35],
        [-120.001, 35],
        [-120.001, 35.001],
        [-120, 35.001],
        [-120, 35]
      ]
    ]
  ]
}

两个哈希映射（即字典）都与 GeoJSON 规范（来源）相同：

{
  "type": "MultiPolygon",
  "coordinates": [
    [
      [
        [-120, 35],
        [-120.001, 35],
        [-120.001, 35.001],
        [-120, 35.001],
        [-120, 35]
      ]
    ]
  ]
}

当然，您也可以从 GeoJSON 文件中读取此数据（显示 Python 示例）：

import json
data = json.loads(geojson_file)

对于一个简单的 Python 包装器，有这个pygeoj库，但是 JSON 数据在 Python 中本地处理得很好，当然在 JavaScript 中也是如此。

您可以轻松地使用 OGR 将数据转换为 shapefile（然后您可以通过代码编辑器上传）或 KML 并将其上传到 FusionTables。

ogr2ogr -f KML output.kml input.json

但是，您的 FeatureCollection 不是有效的 GeoJSON，您必须先修复它。序言应如下所示：

{
    "type": "FeatureCollection",
    "features": [
        {
            "geometry" : { ...
