Adding and Modifying Named Tiles Adding and Modifying Named Tiles The Map Tiling Service uses named tiles to render maps. The named tiles are stored in the repository located in the NamedTiles directory under the root repository. For example, a default installation will place the named tile definition files at http://localhost:8080/RepositoryService/repository/default/NamedTiles To add or modify named tiles in the repository, perform the following: 1. You must be located on the local machine hosting MapInfo Spatial Server and the repository. 2. Use a standard WebDAV protocol tool to access the repository (e.g., Windows WebFolders, DAVExplorer, etc.) and either add or copy the named tiles to or from the repository. For examples of using standard WebDAV tools, see Accessing the Repository using WebDAV Named tiles do not have a file extention, only a name. For a description of the parameters to define named tiles, see: Defining Named Tiles 14 Named tiles are stored in the repository, and define how an individual hosted named map is used by the Map Tiling Service. For each map you want to expose through the Map Tiling Service you must have an equivalent named tile. In the named tile file, the NamedTile element contains the parameters that define the named tile, each of which contains some or all of the following list of child elements: Parameter DisplayName Description ResourceLocation Projection Type string string string string Required yes yes yes yes Description The alias of the named map stored in the map repository. This alias can be different than the actual name of the named map, and will be used in the tiling service requests to call the named tile. The metadata description of the named map. This information is presented to the user when a getDescription call is sent to the Map Tiling Service. The directory and name of the actual named map in the repository, from the repository base. For example, if the named map is located at http://localhost:8080/RepositoryService/repository/default/NamedMaps/World, then you would define the ResourceLocation as /NamedMaps/World. Note: You must specify the starting '/' 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. MapInfo Spatial Server 1.0
Parameter MinimumLevel MaximumLevel TileWidth Bounds MimeList ExpirationDate MapResolution MapRendering RenderLabels PadFactor Map Tiling Service Guide Type integer integer integer string string string integer string boolean integer Chapter 2: Managing Map Tiling Resources and Configuration Required yes yes yes yes no no no no no no Description The minimum zoom level to host the map. Must be greater than zero. See What Is Level? on page 16 for information to help define the level. The maximum zoom level to host the map. Must be greater than zero. See What Is Level? on page 16 for information to help define the level. Width of a tile in pixels. Must be greater than or equal to 16 and must be a number that can be calculated from a 2 n equation (for example 2 4 =16, 2 5 =32, 2 8 =256). The bounds of the map. Coordinates are comma separated and in the coordinate system specified by the projection option. The available types of tiles generated by the tile server for this map only. The date on which the client should delete the map tile from the cache, and request a new copy from the server. The ExpirationDate value must be specified as a W3C formatted date string. Note: The ExpirationDate parameter has effect only when using external caching software such as Squid or Apache. The resolution of the tile images in dots per inch (the number of individual dots that can be placed within the span of one linear inch). If not specified, the GlobalMapResolution is used. The minimum dpi you can define is 72, anything less would render a poor quality image. If a value less than 72 is defined, the service will throw an exception. The rendering quality (anti-alias) of the tile images generated. You can specify either Speed or Quality. If a MapRendering preference is not specified, the global preference in the configuration will be used to determine the maps rendering quality. If neither is specified, the default rendering quality is Speed. Tells the service not to render LabelLayers when generating a tile. The value is case-insensitive. If a RenderLabels preference is not specified, the global preference in the configuration will be used. If neither is specified, the default is 'true'. Used to prevent the clipping of labels when a label crosses a tile boundary. The PadFactor controls the amount of space is rendered around the reques- 15
