在ubuntu 14.04上将lat和lon转换为ELK 6.3版本中的geo point数据类型

我们正在尝试使用ELK版本6.3中的.conf文件和.json（模板文件）将数据推送到elasticsearch . 最初，我们使用模板文件成功地将数据推送到ELK 4.x版本，并能够在 Map 上渲染点 . 但是在新版本中，使用/不使用模板文件，lat和lon只被视为Kibana中的数字 .

我们如何推动lat，lon使其具有地缘点类型？我们正在尝试使用logstash配置文件来推送数据 .

这是我们的.conf文件：

[input
{
    file
        {
        path => "/home/ubuntu/file.csv"
        start_position => "beginning"
        }
}
filter {
    csv {
        separator => ","
        columns => \[
          "CASCADE",
          "Accessibility",
          "Sustainability",

          "lat",
          "lon"


        \]
    }

    mutate { convert => {"lat" => "float"} }
    mutate { convert => {"lon" => "float"} }
    mutate { rename => {"lat" => "\[location\]\[lat\]"} }
    mutate { rename => {"lon" => "\[location\]\[lon\]"} }

}

请告诉我们如何转换为Geo-point
