相信很多人都做过这样的操作,在Server 9.3.1 的时候发布了一个切片服务,然后升级到了Server10,升级后使用旧版本发布的切片服务,或者在另一台新机器上使用这些切片,我们完全不必重新将地图切一次,我们可以继续使用以前切好的地图切片,操作也很容易,只需要随便发布一个地图服务,定义切片的结构,也就是生成切片的缓存方案XML文件(当然要和以前的切片结构是一样的),然后用以前的切片直接覆盖到新的切片目录中对应的目录。

 

   升级到ArcGIS 10.1 for Server可不可以这样做呢,我们知道ArcGIS 10.1 在发布服务的时候其实是用的是msd文档,是用该文档在发布的时候进行很多验证措施,比如空间参考,标注等。

     我们发布地图不能像以前那样随便发布一个MXD文档,因为可能通不过验证。其次ArcGIS Server 10.1 目录结构是有变化的,在10.1 中切片是放在 /home/Soft/ArcGIS/server/arcgis/server/usr/directories/arcgiscache(我用的Linux系统,如果是windows系统,则切片路径在定义的缓存路径下,如D:\arcgisserver\directories\arcgiscache)中的,比如我发布的服务的名称是PointsofInterest,该服务的切片路径是PointsofInterest/home/Soft/ArcGIS/server/arcgis/server/usr/directories/arcgiscache/PointsofInterest/Layers,该目录下的文件如下图:

 

-alllayers目录中是存储切片的目录,而conf.xml文件是该切片服务的描述文件,里面包含切片级别,切片大小,空间参考等信息,conf.cdi文件是10.0增加的,该文件其实也是一个xml文件,里面包含了地图范围,空间参考,切片原点等信息,而Status.gdb是10.1增加的,是一个文件数据库,该数据库中存储了切片的状态信息,比如哪一个级别切片完了,哪一个级别正在切割,以及每一个级别的切片个数和大小,这个我们对我们了解整个切片是有很大的帮助意义的,下图是PointsofInterest的状态:

 

 

按照以前的做法,用已有的切片去覆盖现有的,我在ArcMap中将原来的图添加进来,看到的效果如下(上面的是替换后我新加的服务,下面的是原来的服务)

 

我们看到两个范围,大小都不能完全重合,这说明如果在10.1中直接覆盖或者替换切片是有问题的,原因在什么地方呢?

在10.1中,服务的切片有自己的存放位置,同时相应的服务也有自己的存储位置,服务的存储位置在配置的config-store下面,如我的服务的存储位置如下:/home/Soft/ArcGIS/server/arcgis/server/usr/config-store/services,而每一个服务在该目录下都有一个单独的文件夹,如PointsofInterest.MapServer,该文件夹中含有该服务的一些重要文件,如下图:

lock结尾的文件是锁文件我们不理会,json结尾的文件里面包含了该服务所使用的数据源,服务的地址等信息,具体信息如下所示:

 这个配置文件的信息指向了一个MSD文档 位置为Z:\\home\\Soft\\ArcGIS\\server\\arcgis\\server\\usr\\directories\\arcgissystem\\arcgisinput\\PointsofInterest.MapServer\\extracted\\v101\\PointsofInterest.msd,而这个文档使用的数据/home/Soft/ArcGIS/server/arcgis/server/usr/directories/arcgissystem/arcgisinput/PointsofInterest.MapServer/extracted/v101,这个目录下有一个gdb的数据库,所以这个msd的数据的范围就来自这里(到这里我们可以知道和一个切片服务相关的目录有这些: Services目录,arcgissystem\arcgisinput目录和Cache目录)。按照这个推理,我自己创建了一个要素类,画了几个多边形,发布服务,替换切片,结果又不能让人满意,因为地图服务可以重合但是范围小了,于是我打开这个/extracted/v101目录下的数据跟地图服务叠加,效果如下:

 

 

我们知道ArcGIS 10.1 for Server在发布数据的时候会copy原来数据库中的数据(如果注册了就不用了),Copy后自己重新计算了要素类的范围。

 

   现在原因算是找到了,如果将这个服务的范围修改为跟要替换的切片是一样的,应该就不会有问题。将原先的切片加载到ArcMap中,创建一个范围大小和这个一样的要素类(点,先,面)都可以,我这里用的是面数据,创建后的要素类如下:

 

然后将这个要素类发布服务,在发布的时候,选择定义好的的切片结构,然后选择手动切片,如下图:

这样发布之后然后替换切片目录即可。效果如下图:

 

 

 

通过上面的分析要在10.1中使用早先已经切好的切片,我们用与该切片数据源范围必须一致的数据做地图文档,发布,然后切片,然后替换这样就OK了,那我如何得到原来图的范围呢,10.0的时候我们可以将所有的切片作为一个栅格数据加进来,创建一个等范围的要素类,然后发布服务,然后替换,现在大家知道如何做了吧?
