Adding a Layer To Your Map

TileStream layers can be added via the baseLayers or layers property in your NPMap.config object. Here are the properties that can be set on a TileStream layer object:

Property Type Required? Description
id {String} X id: 'nps.Battle_of_Beaver_Dam_Creek'
type {String} X type: 'TileStream'
name {String} X The name of the layer. This will be used in the base layer selector and/or legend if they have been added to the map.
zIndex {Integer} The zIndex of this layer. If not specified, this will default to 0 if this layer is specified in the "baseLayers" config or null if specified in the "layers" config.

Example

Here is a working example:

{
  id: 'nps.Battle_of_Beaver_Dam_Creek',
  name: '1862',
  type: 'TileStream'
}
