elasticsearch - 无法将GeoJSON与Elasticsearch 5和Kibana 5一起使用

Question

我无法在Elasticsearch中为GeoJSON数据建立索引并使用它们创建Tile Map。

->将GeoJSON发送到ES:

curl -XPUT "http://localhost:9200/datas/data/3617" -d 
'{
    "geometry": {
        "coordinates": [
            7.040691666666667,
            43.626736111111114
        ],
        "type": "Point"
    },
    "properties": {
        "createdAt": {
            "$date": "2016-04-06T15:40:42.402Z"
        },
        "device": "000-0002",
        "ind": 0,
        "timestamp": {
            "$date": "2016-04-06T16:40:41.000Z"
        }
    },
    "type": "Feature"
}'

检查映射

curl -XGET“ http://localhost:9200/datas/data/_mapping”

{
  "datas": {
    "mappings": {
      "data": {
        "properties": {
          "geometry": {
            "properties": {
              "coordinates": {
                "type": "float"
              },
              "type": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              }
            }
          },
          "properties": {
            "properties": {
              "createdAt": {
                "properties": {
                  "$date": {
                    "type": "date"
                  }
                }
              },
              "device": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              },
              "ind": {
                "type": "long"
              },
              "timestamp": {
                "properties": {
                  "$date": {
                    "type": "date"
                  }
                }
              }
            }
          },
          "type": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          }
        }
      }
    }
  }
}

但是在Kibana中创建图块 map 时，在Kibana中出现以下错误:

“没有兼容的字段:“数据”索引模式不包含以下任何字段类型:geo_point”

我应该如何更改映射，以便在Tile Map中使用GeoJSON？

curl -XPUT "http://localhost:9200/datas/_mapping/data" -d '{
    "data": {
       "properties": {
          "geometry": {
             "type": "geo_shape"
          }
       }
    }
  }'

$ curl -XGET "http://localhost:9200/datas/_mapping/data"

curl -XPUT "http://localhost:9200/datas/data/3617" -d

        "coordinates": [
            7.040691666666667,

        ],

}'

=> {“_index”:“数据”，“_ type”:“数据”，“_ id”:“3617”，“_ version”:1，“_ shards”:{“总计”:2，“成功”:1， “失败”:0}，“创建”:true}

但是当我尝试创建平铺 map 时，出现此错误信息



在映射中将geo_shape替换为geo_point时，插入示例数据时出现以下错误:

curl -XPUT "http://localhost:9200/datas/data/3617" -d

    "geometry": {
        "coordinates": [
            7.040691666666667,
            43.626736111111114
        ],
        "type": "Point"
    },
}'

{"error":{"root_cause":[{"type":"parse_exception","reason":"field must be either [lat], [lon] or [geohash]"}],"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"parse_exception","reason":"field must be either [lat], [lon] or [geohash]"}},"status":400}

Answer 1

ES不会直接摄取GeoJSON，而是需要将其转换为适当的 geo_shape ，在您的情况下，它将是point。

首先，您需要创建一个索引和一个映射以接受geo_shape字段，如下所示:

curl -XPUT "http://localhost:9200/datas" -d '{
  "mappings": {
    "data": {
       "properties": {
          "location": {
             "type": "geo_shape"
          }
       }
    }
  }
}'

然后，您可以像下面这样索引您的GeoJSON点:

curl -XPUT "http://localhost:9200/datas/data/3617" -d '{
    "location" : {
        "type" : "point",
        "coordinates" : [7.040691666666667, 43.626736111111114]
    }
}'

更新

如果只需要容纳地理点，则使用 geo_point 而不是 geo_shape会更容易。

curl -XPUT "http://localhost:9200/datas" -d '{
  "mappings": {
    "data": {
       "properties": {
          "location": {
             "type": "geo_point",
             "geohash_prefix": true
          }
       }
    }
  }
}'

curl -XPUT "http://localhost:9200/datas/data/3617" -d '{
    "location" : {
        "lat": 43.626736111111114,
        "lon": 7.040691666666667
    }
}'
