参考 ： https://www.gdal.org/drv_elasticsearch.html
- 下载GDAL
- 下载Elasticsearch
版本的差异可能会导致失败，这次下载的是gdal 2.3.2 ,es5.3
两个文件的win64 二进制包 链接：https://pan.baidu.com/s/149AYKckrdc5mKnCK3wmYGg 密码：a8vm - 将gdal的bin目录添加到path环境变量，将GDAL\bin\gdal\apps也添加到path变量。主要是利用ogr2ogr.
- es的配置需要java环境，具体参考官网 https://www.elastic.co/guide/en/elasticsearch/reference/current/setup.html
- 运行es,在cmd用ogrinfo验证
D:\es5.3>ogrinfo ES:http://localhost:9200
INFO: Open of `ES:http://localhost:9200'
using driver `ElasticSearch' successful.
- 在cmd生成mapping 文件
> ogr2ogr -progress --config ES_WRITEMAP <map的文件路径>\map.txt -f "ElasticSearch" http://localhost:9200 <shapefile的文件路径>\Address_SpatialJoin2new.shp
map文件如下，中间部分字段没贴。如果需要分词或拼音，可在这个文件修改,再重新更新es。

- 在cmd导入shapefile数据
>ogr2ogr -progress -lco BULK_SIZE=5000000 -f "ElasticSearch" http://localhost:9200 <路径>\Address_SpatialJoin2new.shp - 根据空间查询，使用postman发post请求
url :
http://localhost:9200/address_spatialjoin2new/_search
body:
{
"query": {
"bool" : {
"must" : {
"match_all" : {}
},
"filter" : {
"geo_distance" : {
"distance" : "100m",
"geometry.coordinates": [
119.976261537,
30.528380685
]
}
}
}
}
}
这个query的geometry.coordinates的写法需要注意一下，包括坐标的形式，可以参考search直接返回的结果。
