Create Map Tile Package (Data Management)—ArcGIS Pro

Summary

Generates tiles from a map or basemap and packages the tiles to create a single compressed .tpk file.

Usage

The input map must have a description and tags for the tool to execute. To add a description and tags, right-click the map name in the Contents pane, select Properties, and enter a description and tags on the Description tab.
By choosing PNG for the Tiling Format parameter, the tool will automatically select the correct format (PNG8, PNG24, or PNG32) based on the specified Level of Display.
This tool honors the Parallel Processing Factor environment. If the environment is not set (the default) or is set to 100, full parallel processing will be enabled and the tool will attempt to distribute the work to all the logical cores on the machine. Setting the environment to 0 will disable parallel processing. Specifying a factor between 1 and 99 will cause the tool to determine the percentage of logical cores to use by applying the following formula, rounded up to the nearest integer:
```
Parallel Processing Factor / 100 * Logical Cores
```
.
If the result of this formula is 0 or 1, parallel processing will not be enabled.

Syntax

CreateMapTilePackage(in_map, service_type, output_file, format_type, level_of_detail, {service_file}, {summary}, {tags}, {extent}, {compression_quality}, {package_type}, {min_level_of_detail})

Parameter	Explanation	Data Type
in_map	The map from which tiles will be generated and packaged.	Map
service_type	Specifies whether the tiling scheme will be generated from an existing map service or whether map tiles will be generated for ArcGIS Online, Bing Maps, and Google Maps. EXISTING —A tiling scheme from an existing map service will be used. You must specify a map service in the service_file parameter.Choose this option if your organization has created a tiling scheme for an existing service on your server and you want to match it. Matching tiling schemes ensures that your tiles will overlay correctly in your ArcGIS Runtime application.If you choose this option, use the same coordinate system for your source map as the map with the tiling scheme you're importing. ONLINE —The ArcGIS Online/Bing Maps/Google Maps tiling scheme will be used. This is the default.The ArcGIS Online/Bing Maps/Google Maps tiling scheme allows you to overlay your cache tiles with tiles from these online mapping services. ArcGIS Desktop includes this tiling scheme as a built-in option when loading a tiling scheme. When you choose this tiling scheme, the source map must use the WGS 1984 Web Mercator (Auxiliary Sphere) projected coordinate system.The ArcGIS Online/Bing Maps/Google Maps tiling scheme is required if you'll be overlaying your package with ArcGIS Online, Bing Maps, or Google Maps. One advantage of the ArcGIS Online/Bing Maps/Google Maps tiling scheme is that it is widely known in the web mapping world, so your tiles will match those of other organizations that have used this tiling scheme. Even if you don't plan to overlay any of these well-known map services, you may choose the tiling scheme for its interoperability potential.The ArcGIS Online/Bing Maps/Google Maps tiling scheme may contain scales that would be zoomed in too far to be of use to your map. Packaging for large scales can take up much time and disk storage space. For example, the largest scale in the tiling scheme is about 1:1,000. Packaging the entire continental United States at this scale can take weeks and require hundreds of gigabytes of storage. If you aren't prepared to package at this scale level, remove this scale level when you create the tile package.	Boolean
output_file	The output map tile package.	File
format_type	Specifies the format of the generated tiles. PNG —Use PNG to automatically select the correct format (PNG 8, PNG 24, or PNG 32) based on the specified Level of Detail. This is the default. PNG8 —Use PNG 8 for overlay services that need to have a transparent background, such as roads and boundaries. PNG 8 creates tiles of very small size on disk with no loss of information. Do not use PNG 8 if your map contains more than 256 colors. Imagery, hillshades, gradient fills, transparency, and antialiasing can easily push your map over 256 colors. Even symbols such as highway shields may have subtle antialiasing around the edges that unexpectedly adds colors to your map. PNG24 —Use PNG 24 for overlay services, such as roads and boundaries, that have more than 256 colors (if fewer than 256 colors, use PNG 8). PNG32 —Use PNG 32 for overlay services, such as roads and boundaries, that have more than 256 colors. PNG 32 is an especially good choice for overlay services that have antialiasing enabled on lines or text. PNG 32 creates larger tiles on disk than PNG 24. JPEG —Use this format for basemap services that have large color variation and do not need to have a transparent background. For example, raster imagery and very detailed vector basemaps tend to work well with JPEG. JPEG is a lossy image format. It attempts to selectively remove data without affecting the appearance of the image. This can cause very small tile sizes on disk, but if your map contains vector line work or labels, it may produce too much noise or blurry area around the lines. If this is the case, you can attempt to raise the compression value from the default of 75. A higher value, such as 90, may balance an acceptable quality of line work with the small tile size benefit of the JPEG.You decide what image quality you consider acceptable. If you are willing to accept a minor amount of noise in the images, you may save large amounts of disk space by choosing JPEG. The smaller tile size also means the application can download the tiles faster. MIXED —A mixed package uses JPEG in the center of the package and PNG 32 on the edge of the package. Use the mixed mode when you want to cleanly overlay raster packages on other layers.When a mixed package is created, PNG 32 tiles are created anywhere that transparency is detected (in other words, anywhere that the map background is visible). The rest of the tiles are built using JPEG. This keeps the average file size down while providing a clean overlay on top of other packages. If you do not use the mixed mode package in this scenario, you will see a nontransparent collar around the periphery of your image where it overlaps the other package.	String
level_of_detail	The maximum scale at which tiles will be generated for the package. The default is 1. Possible values are 1 through 24. Larger values reflect larger scales that show more detail but take more storage space, while smaller values reflect smaller scales that show less detail and take less storage space. This value must be greater than or equal to min_level_of_detail.	Long
service_file (Optional)	The name of the map service or the XML files to use for the tiling scheme. This parameter is required only when the service_type parameter is EXISTING.	MapServer; File
summary (Optional)	Adds summary information to the properties of the package.	String
tags (Optional)	Adds tag information to the properties of the package. Multiple tags can be added, separated by a comma or semicolon.	String
extent (Optional)	Specifies the extent by manually entering the coordinates in the extent parameter using the format X-Min Y-Min X-Max Y-Max. To use the extent of a specific layer, specify the layer name. MAXOF —The union of inputs will be used. MINOF —The intersection of inputs will be used. DISPLAY —The same extent as the current display will be used. <Layer> —The same extent as the specified layer will be used.	Extent
compression_quality (Optional)	A value between 1 and 100 for the JPEG compression quality. The default value is 75 for JPEG tile format and zero for other formats. Compression is supported only for JPEG and MIXED 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.	Long
package_type (Optional)	Specifies the type of tile package that will be created. tpk —Tiles are stored using Compact storage format. It is supported across the ArcGIS platform. tpkx —Tiles are stored using CompactV2 storage format, which provides better performance on network shares and cloud store directories. This improved and simplified package structure type is supported by newer versions of ArcGIS products such as ArcGIS Online 7.1, ArcGIS Enterprise 10.7, and ArcGIS Runtime 100.5. This is the default.	String
min_level_of_detail (Optional)	The minimum scale at which tiles will be generated for the package. The default is 1. Possible values are 1 through 24. Larger values reflect larger scales that show more detail but take more storage space, while smaller values reflect smaller scales that show less detail and take less storage space. This value must be less than or equal to level_of_detail.	Long
