availableStyles WebMapServiceAvailableLayerStylesTraits[]

The available styles.

availableDimensions WebMapServiceAvailableLayerDimensionsTraits[]

The available dimensions.

parameters any

Additional parameters to pass to the MapServer when requesting images. Style parameters are stored as CSV in styles, dimension parameters are stored in dimensions.

tileWidth number 256

Tile width in pixels. This will be added to GetMap requests for map tiles using the width parameter. Default value is 256 pixels

* previous - the discrete time equal to or before the current continuous time is used.

showInChartPanel boolean

Whether to plot data availability on a chart.

disableDateTimeSelector boolean

multiplierDefaultDeltaStep number 2

The multiplierDefaultDeltaStep is used to set the default multiplier (see TimeVaryingTraits.multiplier trait) - it represents the average number of (real-time) seconds between (dataset) time steps. For example, a value of five would set the multiplier so that a new time step (of this dataset) would appear every five seconds (on average) if the timeline is playing. This trait will only take effect if multiplier is not explicitly set.

ExportableTraits
disableExport boolean

Disable user export functionality

FeatureInfoTraits

A template URL string for fetching feature info. Template values of the form {x} will be replaced with corresponding property values from the picked feature.

show boolean true

Show or hide a workbench item. When show is false, a mappable item is removed from the map and a chartable item is removed from the chart panel.

initialMessage InitialMessageTraits

A message to show when the user adds the catalog item to the workbench. Useful for showing disclaimers.

MinMaxLevelTraits
maxScaleDenominator number

The denominator of the smallest scale (largest denominator) for which tiles should be requested. For example, if this value is 10000, then tiles representing a scale smaller than 1:10000 (i.e. numerically larger denominator, when zooming out further) will not be requested. For large scales set hideLayerBeforeMaxScaleDenominator to true, otherwise you may experience performance issues (requesting too many tiles).

minScaleDenominator number

The denominator of the largest scale (smallest denominator) for which tiles should be requested. For example, if this value is 1000, then tiles representing a scale larger than 1:1000 (i.e. numerically smaller denominator, when zooming in closer) will not be requested. Instead, tiles of the largest-available scale, as specified by this property, will be used and will simply get blurier as the user zooms in closer.

hideLayerAfterMinScaleDenominator boolean

True to hide tiles when the Minimum Scale Denominator is exceeded. If false, we can zoom in arbitrarily close to the (increasingly blurry) layer.

tileErrorHandlingOptions TileErrorHandlingTraits

Options for handling tile errors

clipToRectangle boolean true

Gets or sets a value indicating whether this dataset should be clipped to the {@link CatalogItem#rectangle}. If true, no part of the dataset will be displayed outside the rectangle. This property is true by default, leading to better performance and avoiding tile request errors that might occur when requesting tiles outside the server-specified rectangle. However, it may also cause features to be cut off in some cases, such as if a server reports an extent that does not take into account that the representation of features sometimes require a larger spatial extent than the features themselves. For example, if a point feature on the edge of the extent is drawn as a circle with a radius of 5 pixels, half of that circle will be cut off.

SplitterTraits
splitDirection number

The side of the splitter to display this imagery layer on. Defaults to both sides.

disableSplitter boolean

If true, splitter funcitonality will be hidden for this model.

TimeFilterTraits
timeFilterPropertyName string

The current position picked by the user for filtering

TimeVaryingTraits
currentTime string 2021-09-27T08:07:11.7320000Z

initialTimeSource string now

The initial time to use if Current Time is not specified. Valid values are
* start - the dataset's start time
* stop - the dataset's stop time
* now - the current system time. If the system time is after Stop Time, Stop Time is used. If the system time is before Start Time, Start Time is used.
* none - do not automatically set an initial time
This value is ignored if Current Time is specified.

startTime string

The earliest time for which this dataset is available. This will be the start of the range shown on the timeline control.

stopTime string

The latest time for which this dataset is available. This will be the end of the range shown on the timeline control.

multiplier number

The multiplier to use in progressing time for this dataset. For example, 5.0 means that five seconds of dataset time will pass for each one second of real time.

isPaused boolean true

True if time is currently paused for this dataset, or false if it is progressing.

dateFormat string

A dateformat string (using the dateformat package) used to adjust the presentation of the date in various spots in the UI for a catalog item.
For example, to just show the year set to 'yyyy'. Used in places like the the Workbench Item and Bottom Dock

UrlTraits
url string

The base URL of the file or service.

forceProxy boolean

Force the default proxy to be used for all network requests.

cacheDuration string 0d

The cache duration to use for proxied URLs for this catalog member. If undefined, proxied URLs are effectively cachable forever. The duration is expressed as a Varnish-like duration string, such as '1d' (one day) or '10000s' (ten thousand seconds).
