在使用ArcGIS进行影像、地形等切片时，往往需要保持一致的切片方案才能够更好的加载地图服务。

本文介绍如何获取已经发布好的ArcGIS服务的切片方案xml文件。

当然切片xml文件还可以通过工具
Generate Tile Cache Tiling Scheme
生成，具体操作可参考相关文档，本文不做说明。

示例服务地址：http://localhost:6080/arcgis/rest/services/test/globaltdt5/MapServer

有两种方式获取切片方案xml文件：

1、如果能够直接登录到发布服务的ArcGIS服务器，可以通过服务器对应的文件夹找到conf.xml文件

文件路径（具体路径根据安装情况确定）:D:\arcgisserver\directories\arcgiscache\test_globaltdt5\Layers\Conf.xml

2、如果只是提供了一个服务访问地址，无法登录到指定机器，可通过url获取：

http://localhost:6080/arcgis/rest/directories/arcgiscache/test_globaltdt5/Layers/Conf.xml

说明：rest/directories/arcgiscache对应ArcGIS服务器上的arcgiscache目录：

test_globaltdt5为目录+服务名称：

Layers\Conf.xml为服务目录下的固定名称

注意：不建议使用多种不同切片方案，尤其做三维系统，不论是基于cesium还是基于ArcGIS，建议使用ogc标准的切片方案。

目前大多数都是使用以下切片方案，建议使用该方案（ogc_2000_start_0.xml）：
