Import Map Server Cache (Server)

Summary

Imports tiles from a folder on disk into a map image layer cache.

The source folder can be a child of a registered server cache directory, a folder into which a cache has been previously exported, or a tile package (.tpk).The target service must have the same tiling scheme and the storage format as the source cache.

Usage

• Use this tool to import all or portions of a cache from one folder to another.

• The Overwrite Tiles parameter allows the imported tiles to completely overwrite the existing tiles, rather than blending the images. Imported tiles can still be constrained to an area of interest.

Parameters

Dialog

Label	Explanation	Data Type
Input Service	The map image layer with the cache tiles to be imported. You can choose it by browsing to the desired service in a portal, or you can drag a web tile layer from the Portal tab in the Project pane to supply this parameter.	Image Service; Map Server
Source Cache Type	Imports a cache from a cache dataset or tile package to a cached map or image service running on the server. Map or image service cache—A map or image service cache that is generated using ArcGIS Server. It can be used in ArcGIS Desktop and by ArcGIS Server map or image services. Tile package—A single compressed file where the cache dataset is added as a layer and consolidated so that it can be shared. It can be used in ArcGIS Desktop, ArcGIS Runtime, and mobile apps.	String
Source Cache Dataset (Optional)	The path to the tiles that will be imported. This is represented by a raster dataset icon when you are browsing. You do not have to specify a registered server cache directory; most of the time you'll specify a location on disk where tiles have been previously exported. This location should be accessible to the ArcGIS Server account. If the ArcGIS Server account cannot be granted access to this location, check the Upload data to server parameter.	Raster Dataset
Source Tile Package (Optional)	The path to the tile package that will be imported. This location should be accessible to the ArcGIS Server account. Importing a tile package file to a cached map or image service automatically enables the Upload data to server parameter.	File
Upload data to server (Optional)	Check this parameter if the ArcGIS Server account does not have read access to the source cache. The tool will upload the source cache to the ArcGIS Server uploads directory before moving it to the ArcGIS Server cache directory. Checked—Tiles are placed in the server uploads directory and are then moved to the server cache directory. This is active by default when the Source Cache Type parameter is set to TILE_PACKAGE. Unchecked—Tiles are imported directly into the server cache directory. The ArcGIS Server account must have read access to the source cache.	Boolean
Scales (Optional)	A list of scale levels at which tiles will be imported. By default, the scales listed in the tool dialog box are between the minimum and maximum cached scales for the service. To update the scale range, go to the Service Editor > Caching tab and use the sliders to update the minimum and maximum cached scales.	Double
Number of caching service instances (Optional)	Specifies the number of instances that will be used to update or generate the tiles. The value for this parameter is set to unlimited (-1) and cannot be modified.	Long
Area Of Interest (Optional)	An area of interest polygon that spatially constrains where tiles are imported into the cache. This parameter is useful if you want to import tiles for irregularly shaped areas, as the tool clips the cache dataset, which intersects the polygon at pixel resolution and imports it to the service cache directory. If you do not provide a value for this parameter, the value of the Import Extent parameter will be used. The default is to use the full extent of the map.	Feature Set
Import Extent (Optional)	A rectangular extent defining the tiles to be imported into the cache. By default, the extent is set to the full extent of the map service into which you are importing. Note that the optional parameter on this tool, Area Of Interest, allows you to spatially constrain the imported tiles using an irregular shape. If values are provided for both parameters, the Area Of Interest parameter takes precedence over Import Extent. Current Display Extent —The extent will be based on the active map or scene. This option is only available when there is an active map. Extent of a Layer —The extent will be based on an active map layer. Use the drop-down list to choose an available layer or use the Extent of data in all layers option to get the combined extent of all active map layers, excluding the basemap. This option is only available when there is an active map with layers. Browse —The extent will be based on an existing dataset. Reset Extent —The extent will be reset to the default value. Manually entered coordinates—The coordinates must be numeric values and in the active map's coordinate system. The map may be using different display units	Extent
Overwrite Tiles (Optional)	Specifies whether the images in the destination cache will be merged with the tiles from the originating cache or overwritten by them. Checked—The import replaces all pixels in the area of interest, effectively overwriting tiles in the destination cache with tiles from the originating cache. Unchecked—When the tiles are imported, transparent pixels in the originating cache are ignored by default. This results in a merged or blended image in the destination cache. This is the default.	Boolean

Name	Explanation	Data Type
input_service	The map image layer with the cache tiles to be imported.	Image Service; Map Server
source_cache_type	Imports a cache from a cache dataset or tile package to a cached map or image service running on the server. CACHE_DATASET—A map or image service cache that is generated using ArcGIS Server. It can be used in ArcGIS Desktop and by ArcGIS Server map or image services. TILE_PACKAGE—A single compressed file where the cache dataset is added as a layer and consolidated so that it can be shared. It can be used in ArcGIS Desktop, ArcGIS Runtime, and mobile apps.	String
source_cache_dataset (Optional)	The path to the cache folder matching the data frame name. You do not have to specify a registered server cache directory; most of the time you'll specify a location on disk where tiles have been previously exported. This location should be accessible to the ArcGIS Server account. If the ArcGIS Server account cannot be granted access to this location, set the upload_data_to_server parameter to UPLOAD_DATA.	Raster Dataset
source_tile_package (Optional)	The path to the tile package (.tpk) that will be imported. This location should be accessible to the ArcGIS Server account. When importing a tile package file to a cached map or image service, the upload_data_to_server parameter is ignored as it is automatically set to UPLOAD_DATA.	File
upload_data_to_server (Optional)	Set this parameter to UPLOAD_DATA if the ArcGIS Server account does not have read access to the source cache. The tool will upload the source cache to the ArcGIS Server uploads directory before moving it to the ArcGIS Server cache directory. UPLOAD_DATA—Tiles are placed in the server uploads directory and are then moved to the server cache directory. This is enabled by default when source_cache_type is TILE_PACKAGE. DO_NOT_UPLOAD—Tiles are imported directly into the server cache directory. The ArcGIS Server account must have read access to the source cache.	Boolean
scales [scales,...] (Optional)	A list of scale levels at which tiles will be imported.	Double
num_of_caching_service_instances (Optional)	Specifies the number of instances that will be used to update or generate the tiles. The value for this parameter is set to unlimited (-1) and cannot be modified.	Long
area_of_interest (Optional)	An area of interest polygon that spatially constrains where tiles are imported into the cache. This parameter is useful if you want to import tiles for irregularly shaped areas, as the tool clips the cache dataset, which intersects the polygon at pixel resolution and imports it to the service cache directory. If you do not provide a value for this parameter, the value of the Import Extent parameter will be used. The default is to use the full extent of the map.	Feature Set
import_extent (Optional)	A rectangular extent defining the tiles to be imported into the cache. By default, the extent is set to the full extent of the map service into which you are importing. Note that the optional parameter on this tool, Area Of Interest, allows you to spatially constrain the imported tiles using an irregular shape. If values are provided for both parameters, the Area Of Interest parameter takes precedence over Import Extent. MAXOF—The maximum extent of all inputs will be used. MINOF—The minimum area common to all inputs will be used. DISPLAY—The extent is equal to the visible display. Layer name—The extent of the specified layer will be used. Extent object—The extent of the specified object will be used. Space delimited string of coordinates—The extent of the specified string will be used. Coordinates are expressed in the order of x-min, y-min, x-max, y-max.	Extent
overwrite (Optional)	Specifies whether the images in the destination cache will be merged with the tiles from the originating cache or overwritten by them. OVERWRITE—The import replaces all pixels in the area of interest, effectively overwriting tiles in the destination cache with tiles from the originating cache. MERGE—When the tiles are imported, transparent pixels in the originating cache are ignored by default. This results in a merged or blended image in the destination cache. This is the default.	Boolean
