Convert Map Server Cache Storage Format

Converts the storage of a map or image service cache between the exploded format and the compact format. The tool converts the format in place, meaning it does not make a copy of the existing format of the cache. Instead, it creates the new format of the cache in the same cache folder and deletes the old format.

Make a backup of your cache before running this tool if you think you might want to go back to the old format.

1.    Input Service

The map or image service whose cache format you want to convert. You can drag and drop a map or image service from the Catalog tree to supply this parameter.

2.    Number of caching service instances (optional)

The total number of instances of the System/CachingTools service that you want to dedicate toward running this tool. You can increase the maximum number of instances per machine of the System/CachingTools service using the Service Editor window available through an administrative connection to ArcGIS Server. Ensure your server machines can support the chosen number of instances.

Create Map Server Cache

Creates the tiling scheme and preparatory folders for a map or image service cache. After running this tool, use the Manage Map Server Cache Tiles tool to add tiles to the cache.

1.    Input Service

The map or image service to be cached. You can drag a map or image service from the Catalog tree to supply this parameter.

2.    Service Cache Directory

The parent directory for the cache. This must be a registered ArcGIS Server cache directory.

3.    Tiling Scheme

Specifies how the tiling scheme will be defined. You can define a new tiling scheme with this tool or browse to a predefined tiling scheme file (.xml). A predefined scheme can be created by running the Generate Map Server Cache Tiling Scheme tool.

· NEW—The tiling scheme will be defined using other parameters in this tool to define scale levels, image format, storage format, and so on. This is the default.

· PREDEFINED—The tiling scheme will be defined using an .xml file. You can create a tiling scheme file using the Generate Map Server Cache Tiling Scheme tool.

4.    Predefined Tiling Scheme (optional)

The path to a predefined tiling scheme file (usually named conf.xml).

5.    Scales Type

Specifies how the tiles will be scaled.

· STANDARD—The scales will be automatically generated based on the number specified in the Number of Scales (num_of_scales in Python) parameter. It will use levels that increase or decrease by half from 1:1,000,000 and will start with a level closest to the extent of the source map document. For example, if the source map document has an extent of 1:121,000,000 and three scale levels are defined, the map service will create a cache with scale levels at 1:128,000,000; 1:64,000,000; and 1:32,000,000. This is the default.

· CUSTOM—The cache designer will determine the scales.

6.    Number of Scales

The number of scale levels to create in the cache. This option is disabled if you create a custom list of scales.

7.    Scales (optional)

The scale levels available for the cache. These are not represented as fractions. Instead, use 500 to represent a scale of 1:500, for example.

8.    Dots (Pixels) Per Inch

The dots per inch (DPI) of the intended output device. If a DPI is chosen that does not match the resolution of the output device, the scale of the map tile will appear incorrect. The default value is 96.

9.    Tile Size

Specifies the width and height of the cache tiles in pixels. For the best balance between performance and manageability, avoid deviating from standard widths of 256 by 256 or 512 by 512.

· 128 x 128—128 by 128 pixels.

· 256 x 256—256 by 256 pixels. This is the default.

· 512 x 512—512 by 512 pixels.

· 1024 x 1024—1024 by 1024 pixels.

10. Tiling origin in map units (optional)

The origin (upper left corner) of the tiling scheme in the coordinates of the spatial reference of the source map document. The extent of the source map document must be within (but does not need to coincide with) this region.

11. Cache Tile Format (optional)

Specifies the cache tile format.

· PNG—A PNG format with varying bit depths. The bit depths are optimized according to the color variation and transparency values in a tile. This is the default.

· PNG8—A lossless, 8-bit color, image format that uses an indexed color palette and an alpha table. Each pixel stores a value (0–255) that is used to look up the color in the color palette and the transparency in the alpha table. 8-bit PNG images are similar to GIF images, and most web browsers support transparent backgrounds in PNG images.

· PNG24—A lossless, three-channel image format that supports large color variations (16 million colors) and has limited support for transparency. Each pixel contains three 8-bit color channels, and the file header contains the single color that represents the transparent background. Versions of Internet Explorer earlier than version 7 do not support this type of transparency. Caches using PNG24 are significantly larger than those using PNG8 or JPEG and will use more disk space and require greater bandwidth to serve clients.

· PNG32—A lossless, four-channel image format that supports large color variations (16 million colors) and transparency. Each pixel contains three 8-bit color channels and one 8-bit alpha channel that represents the level of transparency for each pixel. While the PNG32 format allows for partially transparent pixels in the range from 0 to 255, the ArcGIS Server cache generation tool only writes fully transparent (0) or fully opaque (255) values in the transparency channel. Caches using PNG32 are significantly larger than the other supported formats and will use more disk space and require greater bandwidth to serve clients.

· JPEG—A lossy, three-channel image format that supports large color variations (16 million colors) but does not support transparency. Each pixel contains three 8-bit color channels. Caches using JPEG provide control over output quality and size.

· MIXED—The PNG32 format will be created anywhere that transparency is detected (that is, anywhere that the data frame background is visible). The JPEG format will be created for the remaining tiles. This keeps the average file size down while providing a clean overlay on top of other caches.

12. Tile Compression Quality (optional)

The JPEG compression quality (1–100). The default value is 75 for the JPEG tile format and 0 for other formats.

Compression is supported only for the JPEG format. Choosing a higher value will result in a larger file size with a higher-quality image. Choosing a lower value will result in a smaller file size with a lower-quality image.

13. Storage Format (optional)

Specifies the storage format of tiles.

· COMPACT—Tiles will be grouped into large files called bundles. This storage format is efficient in terms of storage and mobility. This is the default.

· EXPLODED—Each tile will be stored as a separate file.
