Vector Layer

Layer Name

type: string
The unique display name and identifier of the layer. It must be unique and contain no special characters.

Kind of Layer

type: enum
A special kind of interaction for the layer. Please see the Kinds page for more.

URL

type: string
A file path that points to a geojson. If the path is relative, it will be relative to the mission’s directory. The URL must contain a proper placeholder ending such as: {z}/{x}/{y}.png. Alternatively vectors can be served with Geodatasets. Simply go to “Manage Geodatasets” at the bottom left, upload a geojson and link to it in this URL field with “geodatasets:{geodataset*name}”

Controlled

type: bool
Whether the layer can be dynamically updated or not. If true, the layer can be dynamically updated and the URL is not required.

If true and a URL is set and Time Enabled is true, the initial url query will be performed.

Legend

type: string
An absolute or relative file path pointing to a legend.csv that describes the symbology of the layer. Please see the Legend Tool to see how to form a legend.csv.

Initial Visibility

type: bool
Whether the layer is on initially.

Visibility Cutoff

type: integer optional If set, this vector layer will be hidden if the current zoom level is less than or equal to that of the visibility cutoff. Visibility Cutoff * -1 will invert its visibility condition. This is useful when the dataset is dense, local to a one region, or irrelevant when far away and the desired range of zoom levels is large.

Initial Opacity

type: float
A value from 0 to 1 of the layer’s initial opacity. 1 is fully opaque.

Time Enabled

type: bool
True if the layer is time enabled. URLs that contain {starttime} or {endtime} will be dynamically replaced by their set values when the layer is fetched.

If true and a URL is set and Controlled is true, only the initial url query will be performed.

Time Type

type: enum [Requery, Local]
When the time changes, whether the layer should Requery the source or filter the layer Locally (based on feature properties. Note that)

Start Time Property Name

type: string optional
Optional and only in use if Time Enabled = true and Time Type = Local. The starting time property path. Setting this is addition to Main Time Property Name casts the feature’s time over a range instead of as a single point in time. Can use dot-notation for nested path. Can be a unix timestamp or an ISO time (end the ISO with a Z to designate that it should be treated as a UTC time).

Main Time Property Name

type: string
Required in Time Enabled = true and Time Type = Local. The main time property path. Can use dot-notation for nested path. Can be a unix timestamp or an ISO time (end the ISO with a Z to designate that it should be treated as a UTC time).

Time Format

type: string optional
The string format to be used in the URL for {starttime} and {endtime}. Defaults to YYYY-MM-DDTHH:mm:ssZ.

Stroke Color

type: CSS color string or a prop optional
The border color of each feature. If the feature is a line, this field is the color of the line. See the Vector Styling page for more. Colors can be as follows:

A named color
- crimson, blue, rebeccapurple
A hex color
- #FFF
- #A58101
An rgb color
- rgb(255,89,45)
An hsl color
- hsl(130, 26%, 34%)
Based on a feature’s color property
- prop:geojson_property_key will set the feature’s color to the values of features[i].properties.geojson_property_key
- If that property is not a valid CSS color and is a string, it will use a random and consistent color based on its hash.

Fill Color

type: CSS color string or a prop optional
The fill color of each feature. See Stroke Color for color options. See the Vector Styling page for more.

Stroke Weight

type: positive integer optional
The thickness of the stroke/border in pixels. See the Vector Styling page for more.

Fill Opacity

type: float optional
A value from 0 to 1 of Fill Color’s opacity. 1 is fully opaque. See the Vector Styling page for more. Note: It’s also possible to set the opacities of colors directly with #CCDDEEFF, rgba() and hsla().

Radius

type: positive integer optional
When a point feature is encountered, this value will be it’s radius in pixels.

Raw Variables

Clicking “Set Default Variables” will add a template of all possible raw variables (without overwriting ones that are already set). All raw variables are optional.

}

useKeyAsName: The property key whose value should be the hover text of each feature. If left unset, the hover key and value will be the first one listed in the feature’s properties. This may also be an array of keys.
dynamicExtent: If true, tries to only query the vector features present in the user’s current map viewport. Pan and zooming causes requeries. If used with a geodataset, the time and extent queries will work out-of-the-box. Otherwise, if using an external server, the following parameters in {} will be automatically replaced on query in the url: starttime={starttime}&endtime={endtime}&startprop={startprop}&endprop={endprop}&crscode={crscode}&zoom={zoom}&minx={minx}&miny={miny}&maxx={maxx}&maxy={maxy}
dynamicExtentMoveThreshold: If dynamicExtent is true, only requery if the map was panned past the stated threshold. Unit is in meters. If a zoom-dependent threshold is desired, set this value to a string ending in /z. This will then internally use dynamicExtentMoveThreshold / Math.pow(2, zoom) as the threshold value.
shortcutSuffix: A single letter to ‘ALT + {letter}’ toggle the layer on and off. Please verify that your chosen shortcut does not conflict with other system or browser-level keyboard shortcuts.
hideMainFeature: If true, hides all typically rendered features. This is useful if showing only *Attachments sublayers is desired. Default false
datasetLinks: Datasets are csvs uploaded from the “Manage Datasets” page accessible on the lower left. Every time a feature from this layer is clicked with datasetLinks configured, it will request the data from the server and include it with it’s regular geojson properties. This is especially useful when single features need a lot of metadata to perform a task as it loads it only as needed.
- prop: This is a property key already within the features properties. It’s value will be searched for in the specified dataset column.
- dataset: The name of a dataset to link to. A list of datasets can be found in the “Manage Datasets” page.
- column: This is a column/csv header name within the dataset. If the value of the prop key matches the value in this column, the entire row will be return. All rows that match are returned.
- type: Unused.
links: Configure deep links to other sites based on the properties on a selected feature. This requires the “Minimalist” option in the Look Tab to be unchecked. Upon clicking a feature, a list of deep links are put into the top bar and can be clicked on to navigate to any other page.
- name: The name of the deep link. It should be unique.
- link: A url template. Curly brackets are included. On feature click, all {prop} are replaced with the corresponding features[i].properties.prop value. Multiple {prop} are supported as are access to nested props using dot notation {stores.food.candy}.
info: Creates an informational record at the top of the page. The first use case was showing the value of the latest sol. Clicking this record pans to the feature specified by which. This requires the “Minimalist” option in the Look Tab to be unchecked. This is used on startup and not when a user selects a feature in this layer.
- which: This only supports the value last at this point.
- icon: Any Material Design Icon name
- value: A name to display. All {prop}s will be replaced by their corresponding features[which].properties[prop] value.
- go: Boolean that, if true, pans and zooms to the feature of which on intial load. The zoom used is Map Scale Zoom or the current zoom. Only the first feature with info.go is gone to.
layerAttachments: Attachments that may apply to the entire layer.
- labels: Place a label beside each feature. Also applies to coordinateAttachments.marker features.
  - initialVisibility: Whether the label sublayer is initially on. Users can toggle sublayers on and off in the layer settings in the LayersTool.
  - theme: Label theme. Either default or solid. Default is white text with a black border. Solid is white text with a dark-grey background box.
  - size: Label size. Either default or large. Default is 14px, large is 16px.
- pairings: Links cross-layer features together. Features paired to this layer will attempt to compute the azimuth-elevation relationship between the two to draw in the Viewer’s PhotoSphere. Additionally, on the Map, a line will be drawn between the two features.
  - initialVisibility: Whether the pairing line sublayer is initially on. Users can toggle sublayers on and off in the layer settings in the LayersTool.
  - layers: An array of names of other layers. Note: Do not use css shorthand color names (“blue”, “maroon”, …) in the paired layers styles as they won’t parse properly when drawing in the PhotoSphere.
  - originOffsetOrder: In many cases, a marker’s center is not the camera’s center. Within a feature’s properties.images objects, originOffset can be defined. originOffsetOrder describes the XYZ order and signage that originOffset should be read in. Possible values are X, -X, Y, -Y, Z, -Z.
  - pairProp: The dot notated path to the feature properties that contains the property to pair on. This layer and all paired layers need this property to properly pair up. A feature in this layer is said to be paired with a feature of one of the other specified layers, if and only if the values of this property in both features matches.
  - layersAzProp: The dot notated path to the feature properties that contains the features’ azimuth. If unset, the azimuth will be calculated through the feature’s longitude, latitude, elevation coordinates.
  - layersElProp:The dot notated path to the feature properties that contains the features’ elevation. If unset, the elevation will be calculated through the feature’s longitude, latitude, elevation coordinates.
  - style: A style object to change the style of the connective lines on the Map between features. (Ex. { “color”: “#00000”, “weight”: 5})
coordinateAttachments: Attachment layers for each coordinate of every feature.

- bearing: Sets the bearing direction (clockwise from north) of this layer’s point markers (or markerIcons if set). Overrides the layer’s shape dropdown value.
  - angleProp: The dot notated path to the feature properties that contains the desired rotation angle. Ex. headings.yaw.
  - angleUnit: Unit of the value of angleProp. Either deg or rad.
  - color: A css color for the directional arrow for non-markerIcon bearings.
- uncertainty: A sublayer feature that places ellipses about point features to indicate positional uncertainty

  - weight: Integer for path thickness in pixels.
markerIcon: Uses an icon image instead of an svg for all of the layer’s point markers. If you’re using this as a bearing marker, make sure the base icon is pointing north.
search: This requires the “Minimalist” option in the Look Tab to be unchecked. When set, this layer will become searchable through the search bar at the top. The search will look for and autocomplete on the properties specified. All properties are enclosed by parentheses and space-separated. round can be used like a function to round the property beforehand. rmunder works similarly but removes all underscores instead.
