描述
将切片从磁盘上的文件夹中导入到地图或影像服务缓存。
源文件夹可以是已注册的服务器缓存目录的子文件夹、之前已向其导出缓存的文件夹或切片包 (.tpk)。目标服务必须与源缓存使用相同的切片方案和存储格式。
使用方法
使用此工具将全部或部分缓存从一个文件夹导入到另一个文件夹。
覆盖切片参数允许导入的切片完全覆盖现有的切片，而不是混合影像。仍可将导入的切片限制在感兴趣区域。
在 10.1 Service Pack 1 中，向该工具中添加了此参数。
语法
arcpy.server.ImportMapServerCache(input_service, source_cache_type, {source_cache_dataset}, {source_tile_package}, {upload_data_to_server}, {scales}, {num_of_caching_service_instances}, {area_of_interest}, {import_extent}, {overwrite})| 参数 | 说明 | 数据类型 |
input_service | 要向其导入切片的地图或影像服务。 这是一个包含服务器和服务器信息的字符串。 要查看构建此字符串的方法，请打开 ArcCatalog，选择目录树中的服务，并注意位置工具栏中的文本。 将反斜线改为正斜线，例如 GIS Servers/arcgis on MYSERVER (admin)/USA.MapServer。 | Image Service; MapServer |
source_cache_type | 将缓存从缓存数据集或切片包导入到服务器上运行的缓存地图或影像服务。
| String |
source_cache_dataset （可选） | 与数据框名称相匹配的缓存文件夹的路径。您不必指定已注册的服务器缓存目录；多数情况下，需要指定磁盘上之前已导入切片的位置。ArcGIS Server 帐户应能访问此位置。如果无法向 ArcGIS Server 帐户授予此位置的访问权限，请将 upload_data_to_server 参数设置为 UPLOAD_DATA。 | Raster Dataset |
source_tile_package （可选） | 将导入的切片包 (.tpk) 所在的路径。ArcGIS Server 帐户应能访问此位置。将切片包文件导入到缓存的地图或影像服务时，将忽略 upload_data_to_server 参数，因为该参数自动设置为 UPLOAD_DATA。 | File |
upload_data_to_server （可选） | 如果 ArcGIS Server 帐户没有源缓存的读取权限，请将此参数设置为 UPLOAD_DATA。工具会在源缓存移至 ArcGIS Server 缓存目录前将其上传到 ArcGIS Server 上传目录。
| Boolean |
scales [scales,...] （可选） | 导入切片时使用的比例级别列表。 | Double |
num_of_caching_service_instances （可选） | 专用于运行该工具的 System/CachingTools 服务实例的总数。 您可以通过 ArcGIS Server 的管理连接，使用服务编辑器窗口，增加 System/CachingTools 服务的每台计算机的最大实例数设置。 确保您的服务器计算机可以支持所选数量的实例。 | Long |
area_of_interest （可选） | 对将切片导入到缓存时所处的位置进行空间约束的感兴趣区。此参数在您想要导入形状不规则区域的切片时非常有用，因为该工具会按像素分辨率裁剪与面相交的缓存数据集，然后将其导入到服务器缓存目录。 如果未提供该参数的值，则将使用导入范围参数的值。默认情况下将使用地图的全图范围。 | Feature Set |
import_extent （可选） | 定义要导入到缓存的切片的矩形范围。默认情况下，此范围将设置为要导入切片所属的地图服务的全图范围。请注意此感兴趣区工具中的可选参数，此工具允许您使用不规则的形状对所导入的切片进行空间约束。如果为两个参数都提供了值，则感兴趣区参数的优先级高于导入范围。 | Extent |
overwrite （可选） | 指定目标缓存中的图像是与原始缓存中的切片合并，还是被其覆盖。
| Boolean |
派生输出
| 名称 | 说明 | 数据类型 |
| out_job_url | 输出 URL。 | 字符串 |
代码示例
ImportMapServerCache 示例 1（独立脚本）
将缓存数据集导入到默认比例级数的缓存服务。接收缓存中的切片将被正在导入的切片所覆盖。
