wcsLayer | Web Map Specification

OGC Web Coverage Service (WCS) is a dynamic image service that follows the specifications of OGC.

Referenced by: baseMapLayer, operationalLayers

Properties

Property	Details
bandIds[]	The band selection for a multispectral dataset
blendMode	Blend modes are used to create various effects by blending colors of top and background layers. `normal` blend mode is the default. Valid values: `average`, `color`, `color-burn`, `color-dodge`, `darken`, `destination-atop`, `destination-in`, `destination-out`, `destination-over`, `difference`, `exclusion`, `hard-light`, `hue`, `invert`, `lighten`, `lighter`, `luminosity`, `minus`, `multiply`, `normal`, `overlay`, `plus`, `reflect`, `saturation`, `screen`, `soft-light`, `source-atop`, `source-in`, `source-out`, `vivid-light`, `xor`
charts[]	An array of chart objects representing charts associated with the layer.
customParameters	A sequence of custom parameters appended to the URL of all requests related to a layer.
disablePopup	Indicates whether to allow a client to ignore popups defined by the service item.
effect	Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work.
id	A unique identifying string for the layer.
interpolation	String indicating the interpolation type. Valid values: `RSP_BilinearInterpolation` `RSP_CubicConvolution` `RSP_Majority` `RSP_NearestNeighbor`
isReference	Applicable if used as a baseMapLayer. A boolean value indicating whether or not the baseMapLayer draws on top (true) of other layers, including operationalLayers , or below (false).
itemId	Unique string value indicating an item registered in ArcGIS Online or your organization’s portal.
layerDefinition	An object that defines the drawing information for image service based layers. See layerDefinition properties table.
layerType	String indicating the layer type. Valid value of this property `WCS`
maxScale	A number representing the maximum scale at which the layer will be visible. The number is the scale’s denominator. Smaller number
minScale	A number representing the minimum scale at which the layer will be visible. The number is the scale’s denominator. Bigger number
multidimensionalDefinition[]	An array of objects representing a slice from multidimensional data. The dimensional definitions in this array are used to filter display data based on slices in one or more dimensions.
multidimensionalSubset	An object representing a subset from multidimensional data. This includes subsets of both variables and dimensions.
opacity	The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.
popupInfo	A popupInfo object defining the content of popup windows when you click or query a pixel.
refreshInterval	Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled.
showLegend	Boolean value indicating whether to display the layer in the legend. Default value is ‘true’.
timeAnimation	This property is applicable to layers that support time. If ‘true’, timeAnimation is enabled.
title	A user-friendly string title for the layer that can be used in a table of contents.
url	The URL to the WCS service.
visibility	Boolean property determining whether the layer is initially visible in the web map.
visibilityTimeExtent	Represents time extent that will control when a layer should be visible based on webmap’s current time. Visibility time extent only affects the layer visibility and will not filter the data.
wcsInfo	Object that defines and provides information about coverages in a WCS service.
