Tile Cache
This is also known as Disk Tile Cache.
Adding the data
| Field | Is it Optional or Required? |
Description |
| Name | Required | An appropriate user added name. |
| Add URL | Required | Enter the URL in the required format, for example http://machinename/TileCache/ TileCache is the name of the IIS virtual or application directory. This location must contain the CacheMetadata.txt file. |
| Layer | Required | You must specify the name of the layer from within the Tile cache that you would like to add. This should be defined in your Tile Cache configuration |
| Image Format | Required | Select from the drop down list the image format that the Tile Cache was created in. |
| Image Checkbox | Ignore | This option is present for legacy support of Web Map Layers 7.1, if using the standard Web Map Layers 8.0 site this parameter can be ignored. |
| Transition Effect | Required | This is set by default to resize, this means that when the map is zoomed, the tile is resized to give the effect that the zoom has taken place immediately, the actual tile is then drawn on top of the resized one as it becomes available. |
| Include in Layer Tree | Optional | This parameter is only applicable if you intend to access the mobile site. Unlike the desktop site, the mobile site does not have a base layer drop down in the top right corner, ticking this option will therefore add the base layer to the Map Features dialog in the What would you like to do? menu, this will allow you to switch between base maps.
If this option is ticked, the layer will not appear in the Map Features dialog of the desktop site. |
| Projection | Required | Choose from a predefined list of SRID numbers to define what projection the data will be drawn in. More SRID numbers can be added in the Projections table of the webMapLayersConfig.db. |
| Visible | Ignore | This option is not yet available in Web Map Layers 8.0, but has been added in preparation for future development. |
| Copyright | Optional | Text entered here will appear across the bottom left of your Web Map Layers 8.0 site. |
| Tile Width | Required | The width of the tiles to be displayed (as defined when the cache was built). |
| Tile Height | Required | The height of the tiles to be displayed (as defined when the cache was built). |
| Use Authenticated Proxy | Optional | Tick this box if your Tile Cache is accessed through an Authenticated Proxy server. |
| Proxy URL | Optional | If using an Authenticated proxy specify the URL here, i.e. http://localhost/webmaplayers8/authenticatedtilecachehandler.axd |
| Proxy User Name | Optional | If using an Authenticated Proxy specify the User Name here. |
| Proxy Password | Optional | If using an Authenticated Proxy specify the Password here. |
Note: When you are adding a tile cache that is to be used as base mapping, you need to ensure that the extents for the CRS given in the Projections table (in the webMapLayersConfig.db) match those that are defined in the tile cache.
For example if you create a Tile Cache in British National Grid with the extents 0,0,700000,1500000 you need to locate the SRID for this projection (27700) in the projections table and ensure that the extents match.
