}

idgroup、iduser、Rod_Length、Soil_type 和 VWC_Mode 是硬编码值

时间为时间戳
VWC 是湿度_avg
EC 是 ec_avg Temp_Soil_F是soil_temp_f_avg
Temp_Soil 为 celcius(soil_temp_f_avg) - 将 salt_temp_f_avg 转换为 celcius

纬度为 (min_lat+ max_lat) / 2
经度为 (min_lng + max_lng) / 2

Answer 1

您可以直接复制硬编码的键值对，同时执行modify规范中的所有计算。请注意，在所有键名称前添加一个通用文字（在本例中为

new_attr_

）前缀，以便能够轻松地拉入下一个类型为 shift 的规范，例如：

[
  {
    "operation": "modify-overwrite-beta",
    "spec": {
      "new_attr_idgroup": "group(7750ceae-0528-44cb-9aeb-8865602d7f6f)",
      "new_attr_iduser": "user(84ca8fa3-199f-4a3e-9c86-699edce12846)",
      "conditions": {
        "new_attr_Time": "=(@(1,timestamp))",
        "new_attr_VMC": "=(@(1,moisture_avg))",
        "new_attr_EC": "=(@(1,ec_avg))",

        "nnew_attr_Latitude": "=doubleSum(@(1,img_extent.min_lat),@(1,img_extent.max_lat))",
        "new_attr_Latitude": "=divideAndRound(6,@(1,nnew_attr_Latitude),2)",
        "nnew_attr_Longitude": "=doubleSum(@(1,img_extent.min_lng),@(1,img_extent.max_lng))",
        "new_attr_Longitude": "=divideAndRound(6,@(1,nnew_attr_Longitude),2)"
      },
      "new_attr_Rod_Length": "S",
      "new_attr_Soil_type": "D",
      "new_attr_VWC_Mode": "V"
    }
  },
  {
    "operation": "shift",

      "new_attr_*": "&(0,1)",//extract the 1st replacement for he asterisk of the current(0th) level
