导出地图服务器缓存 (服务器)

摘要

将切片从地图缓存导出至磁盘上的文件夹中。切片可导入至其他缓存，也可独立于其父服务作为栅格数据集从 ArcGIS Desktop 中访问。

用法

• 运行此工具前，在磁盘上创建文件夹，以保存导出的切片。

语法

ExportMapServerCache_Server (server_name, object_name, data_frame, target_cache, {export_extent}, {levels}, thread_count, storage_format_type, {export_feature_class})

参数	说明	数据类型
server_name	对缓存切片将被导出的服务进行托管的 ArcGIS Server 计算机。	String
object_name	切片将被导出的地图服务。	String
data_frame	地图服务的源数据框。	String
target_cache	缓存将被导出到的目标文件夹。此文件夹不必 是已注册的服务器缓存目录。	Folder
export_extent （可选）	定义要导出的切片的矩形范围。默认情况下，此范围被设置为服务的源地图的全图范围。请注意此工具的可选参数，它用于选择性地将切片导出限制为要素类边界。	Extent
levels [levels,...] （可选）	导出切片时使用的比例级别列表。	Double
thread_count	导出缓存时使用的地图服务实例的数量。默认情况下，使用实例的最大允许数量（对于 ArcGIS Server 服务，其默认值是 2）。如果服务器功能更强大，则可以在服务属性 中增加实例的最大允许数量，然后在运行此工具时增大此参数。	Long
storage_format_type	导出的缓存的存储格式。 紧密 —切片被分组到包文件中以节省磁盘空间及允许以较快的速度复制缓存。 松散 —每个文件都作为单个文件存储（在 ArcGIS Server 10 之前的版本中，以这种方式总是存储缓存）。	String
export_feature_class （可选）	定义从缓存导出切片的位置的面要素类。它用于导出形状不规则的区域。	Feature Class

代码示例

该示例使用 ExportMapServerCache 导出用于四种比例的整个地图缓存。

# Name: ExportMapServerCache.py
# Description: The following stand-alone script demonstrates how to export cache

# Requirements: os, sys, time and traceback modules

# Any line that begins with a pound sign is a comment and will not be executed
# Empty quotes take the default value.
# To accept arguments from the command line replace values of variables to

该示例根据要素类的边界，使用 ExportMapServerCache 导出地图缓存。
