SymbolLayerOptions interface
Options used when rendering geometries in a SymbolLayer.
- Extends
Properties
icon |
Options used to customize the icons of the symbols. See IconOptions for defaults. |
line |
Distance in pixels between two symbol anchors along a line. Must be greater or equal to 1.
Default |
placement | Specifies the label placement relative to its geometry. |
sort |
Sorts features in ascending order based on this value. Features with
lower sort keys are drawn and placed first.
Default |
source | The id or instance of a data source which the layer will render. |
source |
Required when the source of the layer is a VectorTileSource. A vector source can have multiple layers within it, this identifies which one to render in this layer. Prohibited for all other types of sources. |
text |
Options used to customize the text of the symbols. See TextOptions for defaults. |
z |
Determines whether overlapping symbols in the same layer are rendered in the order
that they appear in the data source, or by their y position relative to the viewport.
To control the order and prioritization of symbols otherwise, use |
Inherited Properties
filter | An expression specifying conditions on source features. Only features that match the filter are displayed. |
max |
An integer specifying the maximum zoom level to render the layer at.
This value is exclusive, i.e. the layer will be visible at |
min |
An integer specifying the minimum zoom level to render the layer at.
This value is inclusive, i.e. the layer will be visible at |
visible | Specifies if the layer is visible or not.

iconOptions?: IconOptions
Property Value
lineSpacing
Distance in pixels between two symbol anchors along a line. Must be greater or equal to 1.
Default 250
.
lineSpacing?: number | PropertyValueSpecification<number>
Property Value
number | PropertyValueSpecification<number>
placement
Specifies the label placement relative to its geometry.
"point"
: The label is placed at the point where the geometry is located.
"line"
: The label is placed along the line of the geometry.
Can only be used on LineString and Polygon geometries.
"line-center"
: The label is placed at the center of the line of the geometry.
Can only be used on LineString
and Polygon
geometries
Default "point"
.
placement?: "point" | "line" | "line-center"
Property Value
"point" | "line" | "line-center"
sortKey
Sorts features in ascending order based on this value. Features with
lower sort keys are drawn and placed first.
Default undefined
.
sortKey?: number | DataDrivenPropertyValueSpecification<number>
Property Value
number | DataDrivenPropertyValueSpecification<number>
source
The id or instance of a data source which the layer will render.
source?: string | Source
Property Value
string | Source
sourceLayer
Required when the source of the layer is a VectorTileSource. A vector source can have multiple layers within it, this identifies which one to render in this layer. Prohibited for all other types of sources.
sourceLayer?: string
Property Value
string
textOptions
Options used to customize the text of the symbols.
See TextOptions for defaults.
textOptions?: TextOptions
Property Value
zOrder
Determines whether overlapping symbols in the same layer are rendered in the order
that they appear in the data source, or by their y position relative to the viewport.
To control the order and prioritization of symbols otherwise, use sortKey
.
"auto"
: Sorts symbols by sortKey
if set. Otherwise behaves like "viewport-y"
.
"viewport-y"
: Sorts symbols by their y position if allowOverlap
is true
or
if ignorePlacement
is false
.
"source"
: Sorts symbols by sortKey
if set. Otherwise, symbols are rendered in the
same order as the source data.
Default "auto"
zOrder?: "auto" | "viewport-y" | "source"
Property Value
"auto" | "viewport-y" | "source"

minZoom?: number
Property Value
number
Inherited From LayerOptions.minZoom
visible
Specifies if the layer is visible or not.
Default true
