ArcMap地理编码服务的发布与使用


教程目录

一、引言


        地理编码是按照主要是地理位置描述与地理坐标的相互转换,主要包括地理编码与反地理编码。

        地理编码指的是根据地名获取位置信息;

        反地理编码指的是根据位置信息获取地名;

        这个的使用我们要根据需求来做,其实这个功能类似mapservice中的空间查询与属性查询,自我感觉两者可以代替,猜测出这个服务的目的:数据量大的时候可能效率高,比较常用。



二、地理编码服务发布



1、创建locator


  • toolbox中找到创建locator工具



  • 按照提示添加参数,第一个locator样式,第二个shp数据,第三个查询字段,最后别忘了往下拉一下选择输出位置



  • 下图是创建的locator




2、发布地理编码服务


  • 右击locator,选择share as——geocode service


  • 然后就跟普通map service发布类似了,直接掠过


  • 最后参数设定,直接分析发布ok



  • 发布之后的geocode service





三、地理编码服务在arcgis js中的使用

2、反地理编码


这个反地理编码自己写的有点问题,老是说无效的参数直接找了网上一个,调用的在线的地图与服务,大家可以参考下
