Question

type sols3json.json | jq-win64.exe  "[.[] | { "type": "FeatureCollection","features":[{  type: "Feature", "geometry":  {"type": "LineString","coordinates":  [  [.OpStartLongitude, .OpStartLatitude| tonumber],  [ .OpEndLongitude, .OpEndLatitude | tonumber] ]  },  properties: {name: .SolName}}]}"  > sols3.geojson

我得到jq：错误：语法错误，意外的$ end（Windows cmd shell引用问题？）我究竟做错了什么？输出应如下所示：

{
"type": "FeatureCollection",
"features": 
    [
    {
    "properties": {
    "ccaa": "CATALUNYA",
    "prov": "LLEIDA",
    "dir": "N-IIA/SOSES/TORRES DE SEGRE/ALCARRàS",
    "roadnumber": "A-2",
    "tmc": "E17+02413"
    },
    "geometry": {
    "coordinates": [
    [
    0.4714937,
    41.5420936
    ],
    [
    0.4891472,
    41.5497014
    ]
    ],
    "type": "LineString"
    },
    "type": "Feature"
    }
    ]
}

您的问题尚不清楚，但是我理解正确，这很可能是您想要的。

提供的输入文件是：

[
  {
    "TMC": "E17+02412",
    "ROADNUMBER": "A-2",
    "DIR": "E-90/AP-2/BARCELONA-ZARAGOZA (SOSES)",
    "PROV": "LLEIDA",
    "CCAA": "CATALUNYA",
    "StartLatitude": "41.5368273",
    "StartLongitude": "0.4387071",
    "EndLatitude": "41.5388396",
    "EndLongitude": "0.4638462"
  }
]

您可以使用以下jq过滤器过滤内容：

jq 'map({ type: "Feature", "geometry": {"type": "LineString","coordinates": [ [.StartLongitude, .StartLatitude| tonumber], [ .EndLongitude, .EndLatitude | tonumber] ] }, properties: {tmc: .TMC, roadnumber: .ROADNUMBER, dir: .DIR, prov: .PROV, ccaa: .CCAA}})' file

产生新的JSON数据：

[
  {
    "type": "Feature",
    "geometry": {
      "type": "LineString",
      "coordinates": [
        [
          0.4387071,
          41.5368273
        ],
        [
          0.4638462,
          41.5388396
        ]
      ]
    },
    "properties": {
      "tmc": "E17+02412",
      "roadnumber": "A-2",
      "dir": "E-90/AP-2/BARCELONA-ZARAGOZA (SOSES)",
      "prov": "LLEIDA",
      "ccaa": "CATALUNYA"
    }
  }
]
