A CatalogItem representing CSV data.

Initialization File properties:

"type": "csv"


The name of the item to show in the catalog, if different from name. Default undefined. This property is observed.


The names of items in the CatalogMember's info array that contain details of the source of this CatalogMember's data. This should be overridden by children of this class.


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).


The character set of the data, which overrides the file information if present. Default is undefined.


A HTML string to show above the chart as a disclaimer


The dictionary of custom item properties.


The data, represented as a binary Blob, a string, or a Promise for one of those things. If this property is set, CatalogItem's url is ignored.


A description of the custodian of this data item. This property is an HTML string that must be sanitized before display to the user.


The URL from which the TableCatalogItem's data was obtained. This is informational; it is not used. This propery is observable.


The URL from which this data item's raw data can be retrieved, or undefined if raw data for this data item is not available.


The type of the CatalogItem's dataUrl, or undefined if raw data for this data source is not available. Valid values are: * direct - A direct link to the data. * wfs - A Web Feature Service (WFS) base URL. If CatalogItem's dataUrl is not specified, the base URL will be this data item's URL. * wfs-complete - A complete, ready-to-use link to download features from a WFS server. * none - There is no data link.


Options for formatting current time and timeline tic labels. Options are: currentTime // Current time in time slider will be shown in this format. For example "mmmm yyyy" for Jan 2016. timelineTic // Timeline tics will have this label. For example "yyyy" will cause each tic to be labelled with the year.


The description of the item.


A flag which determines whether the legend comes before (false) or after (true) the display variable choice. Default false.


A template to display message in a info box. May be a string or an object with template, name and/or partials properties.


Gets or sets whether or not this member should be forced to use a proxy. This property is not observable.


Indicates that the source of this data should be hidden from the UI (obviously this isn't super-secure as you can just look at the network requests).


An optional unique id for this member, that is stable across renames and moves. Use uniqueId to get the canonical unique id for this CatalogMember, which is present even if there is no id.


A message object that is presented to the user when an item or group is initially clicked The object is of the form {title:string, content:string, key: string, confirmation: boolean, confirmText: string, width: number, height: number}.


Options for the value of the animation timeline at start. Valid options in config file are: initialTimeSource: "present" // closest to today's date initialTimeSource: "start" // start of time range of animation initialTimeSource: "end" // end of time range of animation initialTimeSource: An ISO8601 date e.g. "2015-08-08" // specified date or nearest if date is outside range


Flag to be used for charting, whether this item is generated for the purposes of drawing a chart


A value indicating whether this data item is enabled. An enabled data item appears in the "Now Viewing" pane, but is not necessarily shown on the map.


A value indicating whether this item is hidden from the catalog. This property is observable.


A value indicating whether the legend for this data item is currently visible.


A value indicating whether this data source is currently loading.


A value indicating whether this data source can be shown on the map (as opposed to a time-series dataset, for instance, which can only be shown in a chart).


A value indicating whether this item is kept above other non-promoted items.


A value indicating whether the rows correspond to "sampled" data. This only makes a difference if there is a time column and idColumns. In this case, if isSampled is true, then feature position, color and size are interpolated to produce smooth animation of the features over time. If isSampled is false, then times are treated as the start of periods, so that feature positions, color and size are kept constant from one time until the next, then change suddenly. Color and size are never interpolated when they are drawn from a text column.


A value indicating whether this data item is currently shown on the map. In order to be shown, the item must also be enabled.


A value indicating whether this member was supplied by the user rather than loaded from one of the Terria's initSources. User-supplied members must be serialized completely when, for example, serializing enabled members for sharing.


Whether this catalog member is waiting for a disclaimer to be accepted before showing itself.


Keeps the layer on top of all other imagery layers.


The URL of the legend to show when this catalog item is enabled. If there is more than one legend URL, this property returns the first one.


The URLs of the legends to show when this catalog item is enabled.


The maximum number of features whose information can be shown at one time in the Feature Info Panel, from this item. Defaults to terria.configParameters.defaultMaximumShownFeatureInfos


The URL from which this data item's metadata description can be retrieved, or undefined if metadata is not available for this data item. The format of the metadata depends on the type of data item. For example, Web Map Service (WMS) data items provide their metadata via their GetCapabilities document.


The name of the item.


The name of this catalog member in the catalog. By default this is just name, but can be overridden.


The index of the item in the Now Viewing list. Setting this property does not automatically change the order. This property is used intenally to save/restore the Now Viewing order and is not intended for general use.


A message to show when this item is enabled for the first time in order to call attention to the Now Viewing panel.


The opacity (alpha) of the data item, where 0.0 is fully transparent and 1.0 is fully opaque.


The geographic rectangle (extent or bounding box) containing this data item.


A short report to show on the now viewing tab.


Should any warnings like failures in region mapping be displayed to the user?


A value indicating whether this data source should show an info icon.


The URL of this data.


A flag indicating whether imagery should be displayed using this item's own clock (currentTime, multiplier), or, if false, the terria clock (whose current time is shown in the timeline UI). Default false.


A value indicating whether the map will automatically zoom to this catalog item when it is enabled.

Note that within a single init source:

  • Catalog items with both isEnabled and zoomOnEnable set to true will override the top-level initialCamera property.
  • If multiple catalog items have both isEnabled and zoomOnEnable set to true, it is undefined which one will affect the camera.

In the case of multiple init sources, however, the camera will reflect whatever happens in the last init source, whether it is a result of a zoomOnEnable or an initialCamera,
