Tile Details Page

When you click or select a named tile in Spatial Manager, a page appears with detailed information about that resource.

Tile Name
The name of the named tile. To rename the tile, hover over the name and click the pencil icon to enter edit mode (see Renaming Named Resources and Folders).
A description of the named tile. Click Add to enter a description or click an existing description to edit it. There are no restrictions on what you can enter for a description, including no minimum required number of characters.
Words or phrases that describe your repository content and allow you to more effectively search the repository. If you have the necessary permissions, you can add, edit (by moving your mouse over the keywords so that a pencil icon appears), and delete keywords. To keep your set of keywords manageable and easier to search, case is respected (for example, you are allowed to add the keyword "MyMap) but variations by case are not allowed (for example, you cannot have two separate keywords for "MyMap" and "mymap").
Resource Info Tab
Information about the resource, including its name (that is, its path in the repository), the named map that the tile references (displayed either as a link to a named map or a path for an inline reference), its type (named tile), the date it was created, and the date it was last modified (displayed in the locale of your browser).
Settings Tab

Displays properties for the named tile.

Property Description
Coordinate System The coordinate system projection to host the named map. The Map Tiling Service will transform the named map into the projection defined. The projection is defined using the EPSG format. For best results, use epsg:3857 (Popular Visualization CRS or "Popular Mercator").
Bounds The tile bounds define the full extent of the tiled map in units of the selected coordinate system.
Tile Levels The minimum and maximum zoom levels to host the map. Values range from 1 to 25. The level shows how close the map image is to the Earth. Level 1 is the furthest away and is composed of one tile that the entire map will be drawn into. For more information, see What Is Tile Level? .
Tile Expiration HTTP clients (such as web browsers) cache and re-use map tiles to improve performance. This optional setting is the date or age of the tile on which the HTTP client should replace the map tile in its cache with a new copy that it requests from the server. This field displays either a date (YYYY-MM-DD) or a time value in days. See http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html for more information about HTTP client caching.
Image Settings  
Image Formats The available image (mime) types (PNG, GIF, or JPG/JPEG) of tiles generated by the tile server for the named map. If a preference is not specified, the default is PNG.
Tile Width Width of a tile in pixels. Must be greater than or equal to 16.
Pad Factor Used to prevent the clipping of labels when a label crosses a tile boundary. Controls the number of tiles that are rendered around the requested tile, with 0 meaning no padding, 1 meaning padding of 1 tile around the requested tile. If a preference is not specified, the global preference in the configuration will be used. If neither is specified, the default is 1.0. More padding results in less label or symbol clipping, however performance is negatively affected by a high pad factor.
Background Opacity The level of background opacity (transparency) for the tile images displayed as a percent, where 0% is completely transparent and 100% is completely opaque.
Render Labels Choose to render existing label layers on the map when generating a tile. If a preference is not specified, the default is Yes.
