给定一个data.tsv文件:

id  code    name
1   AL  Alabama
2   AK  Alaska
4   AZ  Arizona
5   AR  Arkansas
6   CA  California
... ... ...

给定topojson.json文件:(结构正确,数值是随机的)

{ 
"type":"Topology",
"transform": 
    {
    "scale": [0.0015484881821515486,0.0010301030103010299],
    "translate":[-5.491666666666662,41.008333333333354]
    },
"objects": 
    {
    "states":
        {
        "type":"GeometryCollection",
        "geometries": 
            [
            {"type":"Polygon","arcs":[[0]],"properties":{"code_2":"AL"}},
            {"type":"Polygon","arcs":[[1]],"properties":{"code_2":"AK"}}
            ]
        }
    },
"arcs":
    [
        [[2466,9916],[-25,-5],[3,-13]],
        [[2357,9852],[1,-2],[1,-2]]
    ]
}

如何使用公共字段(1)将其他字段(2)的值注入json文件？

1]:data.txt#code和topojson.txt.objects.states.geometries.properties.code_2

2]: data.txt#name

最终结果应包含:

            {"type":"Polygon","arcs":[[0]],"properties":{"code_2":"AL", "name":"Alabama" }},
            {"type":"Polygon","arcs":[[1]],"properties":{"code_2":"AK", "name":"Alaska" }},

编辑:接受的答案:

topojson -o final.json -e data.tsv --id-property=code_2,code -p code_2,state=name -- topojson.json
