dependencyDeck.GL layers can be added to the map with Map.add_deck_layers
.
They are defined as a dictionary, where classes got the @@type
prefix and getter props the @@=
prefix. They are inserted into the layer stack of the maplibre context. Therefore, you can also pass a beforeId
prop.
Here is an example corresponding to the Deck.GL GridLayer API Example:
grid_layer = {\n \"@@type\": \"GridLayer\", # JS: new GridLayer\n \"id\": \"my-awsome-grid-layer\",\n \"data\": \"https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/sf-bike-parking.json\",\n \"extruded\": True,\n \"getPosition\": \"@@=COORDINATES\", # JS: d => d.COORDINATES\n \"getColorWeight\": \"@@=SPACES\", # JS: d => d.SPACES\n \"getElevationWeight\": \"@@=SPACES\", # JS: d => d.SPACES\n \"elevationScale\": 4,\n \"cellSize\": 200,\n \"pickable\": True,\n \"beforeId\": \"first-labels-layer\" # optional\n }\n
The Code above will generate the following JavaScript code:
const gridLayer = new GridLayer({\n id: 'GridLayer',\n data: 'https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/sf-bike-parking.json',\n extruded: true,\n getPosition: d => d.COORDINATES,\n getColorWeight: d => d.SPACES,\n getElevationWeight: d => d.SPACES,\n elevationScale: 4,\n cellSize: 200,\n pickable: true\n});\n

"},{"location":"layers/","title":"Layers","text":"The paint
and layout
properties for the layers depend on the type of the layer. They are passed as a dict
corresponding to the Layer Style Spec.
For example, to set the radius and the color for a circle layer, the paint
property looks like this:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": \"yellow\"\n}\n
The value for any layout
property, paint
property, or filter
may also be specified as an expression. For details see Expressions.
For example, if the source of your layer has a color
property that contains the color of the feature, you can use the following expression:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": [\"get\", \"color\"]\n}\n
A more complex expression where the color depends on the type
property of the layer's source might look like this:
paint={\n \"circle-color\": [\n \"match\",\n [\"get\", \"type\"],\n # darkred if type == \"mid\"\n \"mid\",\n \"darkred\",\n # darkgreen if type == \"major\"\n \"major\",\n \"darkgreen\",\n # else blue\n \"darkblue\",\n ]\n}\n
Filter features of a source according to its magnitude
property:
# Only show features where magnitude >= 5\nfilter = [\">=\", [\"get\", \"magnitude\"], 5]\n

dependencyDeck.GL layers can be added to the map with Map.add_deck_layers
.
They are defined as a dictionary, where classes got the @@type
prefix and getter props the @@=
prefix. They are inserted into the layer stack of the maplibre context. Therefore, you can also pass a beforeId
prop.
Here is an example corresponding to the Deck.GL GridLayer API Example:
grid_layer = {\n \"@@type\": \"GridLayer\", # JS: new GridLayer\n \"id\": \"my-awsome-grid-layer\",\n \"data\": \"https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/sf-bike-parking.json\",\n \"extruded\": True,\n \"getPosition\": \"@@=COORDINATES\", # JS: d => d.COORDINATES\n \"getColorWeight\": \"@@=SPACES\", # JS: d => d.SPACES\n \"getElevationWeight\": \"@@=SPACES\", # JS: d => d.SPACES\n \"elevationScale\": 4,\n \"cellSize\": 200,\n \"pickable\": True,\n \"beforeId\": \"first-labels-layer\" # optional\n }\n
The Code above will generate the following JavaScript code:
const gridLayer = new GridLayer({\n id: 'GridLayer',\n data: 'https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/sf-bike-parking.json',\n extruded: true,\n getPosition: d => d.COORDINATES,\n getColorWeight: d => d.SPACES,\n getElevationWeight: d => d.SPACES,\n elevationScale: 4,\n cellSize: 200,\n pickable: true\n});\n

"},{"location":"layers/","title":"Layers","text":"The paint
and layout
properties for the layers depend on the type of the layer. They are passed as a dict
corresponding to the Layer Style Spec.
For example, to set the radius and the color for a circle layer, the paint
property looks like this:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": \"yellow\"\n}\n
The value for any layout
property, paint
property, or filter
may also be specified as an expression. For details see Expressions.
For example, if the source of your layer has a color
property that contains the color of the feature, you can use the following expression:
paint = {\n \"circle-radius\": 5,\n \"circle-color\": [\"get\", \"color\"]\n}\n
A more complex expression where the color depends on the type
property of the layer's source might look like this:
paint={\n \"circle-color\": [\n \"match\",\n [\"get\", \"type\"],\n # darkred if type == \"mid\"\n \"mid\",\n \"darkred\",\n # darkgreen if type == \"major\"\n \"major\",\n \"darkgreen\",\n # else blue\n \"darkblue\",\n ]\n}\n
Filter features of a source according to its magnitude
property:
# Only show features where magnitude >= 5\nfilter = [\">=\", [\"get\", \"magnitude\"], 5]\n
