WMS (OGC Web Map Service)

This allows you to add a single layer from your WMS (unlike WMS from Capabilities which adds all layers being served out by the defined URL).

Note: To use this service your data SHOULD be served out as a WMS. This can be done through GeognoSIS.

After adding the URL, manually add the name of the layer you wish to add using Add Layer. Or use the Get info from capabilities option and select the layer you wish to add.

This will use information in the capabilities document to automatically populate a number of fields.

Field	Is it Optional or Required?	Description
Layer Type	Required	The overlay type selected from the drop-down list.
Name	Required	Enter a Name to appear in the More Mapping dialog.
Add URL	Required	URL attained from the WMS capabilities document. This can be accessed from the GeognoSIS Manager.
Get info from capabilities	Optional	Click this button to display a list of the available layers from the supplied WMS URL.
Add Layer	Optional You can use this or Get info from capabilities	If you know the name of the layer, enter it in this field.
Copyright	Optional	Text entered here appears on the bottom left of your user site.
Buffer	Required	Creates a buffer of tiles outside the visible map frame. By default this value is set to zero. Setting a buffer gives you a smoother experience when panning round the map; however it creates a larger request to the server meaning the server is busier for longer and the site can be slower to load.
Version	Required	Automatically populated when you select a layer using Get info from capabilities (if not filled automatically, ensure you add the details manually.)
Is Base Layer	Optional	All layers added are assumed to be a data layer unless this box is ticked.
Include in Layer Tree		If the data is being served out as a base layer and the site accessed on a mobile device, this option allows you to switch between base layers in the Map Features dialog. (The base layer selector on the top right of the site is not included in the mobile version of Cadcorp SIS WebMap).
Visible	Required	Tick this checkbox for data to appear on the map and in the Map Features dialog.
Single Tile	Optional	Tick this checkbox to return the whole map as a single tile. A single tile reduces the number of requests made to the server however it prevents the map from appearing as a slippy map. If you pan around, the whole tile is reloaded for the new location.
Projection	Required	A predefined list of SRID numbers that specifies the projection the data will be drawn in. NOTE: More SRID numbers can be added in the Projections table of the webMapLayersConfig.db.
Transition Effect	Required	This defines how the map transitions between zoom levels.
Image Format	Required	Sets the image format of the served data.
Show Legend Button	Required	This is legacy support of Web Map Layers 7.1. Ignore this parameter if using the standard Cadcorp SIS WebMap site.
Image Checkbox	Ignore	This is legacy support of Web Map Layers 7.1. Ignore this parameter if using the standard Cadcorp SIS WebMap site.
Legend URL	Optional	Add this information manually; this information can be found in the capabilities document in your GeognoSIS Manager. See Access Information to add a WMS Legend.
Legend Image Width	Optional	This can be found in the capabilities document in your GeognoSIS Manager.
Legend Image Height	Optional	This can be found in the capabilities document in your GeognoSIS Manager.
Exceptions	Optional	The format in which an exception is returned. It can be set to INIMAGE where the exception message is displayed in the image or BLANK so that no image is returned.
Abstract	Optional	Text entered here appears as metadata next to the layer on your Cadcorp SIS WebMap site.
Tile Width	Optional	If not using the single tile option, data requests from GeognoSIS will be returned in tiles. This value refers to the tile width (measured in number of pixels). The width is set to 256 as default.
Tile Height	Optional	If not using the single tile option, data requests from GeognoSIS will be returned in tiles. This value refers to the tile height (measured in number of pixels). The width is set to 256 as default.
Display Outside Max Extent	Optional	Displays data even if it is outside the maximum extents set for the map.
Num Zoom Levels	Ignore	This property can currently be ignored.
Use Authenticated Proxy	Optional	Tick this checkbox if your WMS is accessed through an Authenticated Proxy server.
Proxy Url	Optional	If using an Authenticated Proxy specify the URL here. Example of a Proxy url: http:// {MachineName}/Webmaplayers8/AuthenticatedTileCacheHandler.axd. MachineName may be localhost.
Proxy User Name	Optional	Enter User Name of the Authenticated Proxy.
Proxy Password	Optional	Enter Password for the Authenticated Proxy.
