|
|
* Instead of running one query for every layer, the query is fused.
|
|
*
|
|
* Afterwards, every layer is given the list of features.
|
|
* Every layer takes away the features that match with them*, and give the leftovers to the next layers.
|
|
*
|
|
* This implies that the _order_ of the layers is important in the case of features with the same tags;
|
|
* as the later layers might never receive their feature.
|
|
*
|
|
* *layers can also remove 'leftover'-features if the leftovers overlap with a feature in the layer itself
|
|
*
|
|
* Note that builtin layers can be reused. Either put in the name of the layer to reuse, or use {builtin: "layername", override: ...}
|
|
*
|
|
* The 'override'-object will be copied over the original values of the layer, which allows to change certain aspects of the layer
|
|
*
|
|
* For example: If you would like to use layer nature reserves, but only from a specific operator (eg. Natuurpunt) you would use the following in your theme:
|
|
*
|
|
* ```
|
|
* "layer": {
|
|
* "builtin": "nature_reserve",
|
|
* "override": {"source":

* {"osmTags": {
|
|
* "+and":["operator=Natuurpunt"]

* }
|
|
* }
|
|
* }
|
|
* }
|
|
* ```
|
|
*
|
|
* It's also possible to load multiple layers at once, for example, if you would like for both drinking water and benches to start at the zoomlevel at 12, you would use the following:
|
|
*
|
|
* ```
|
|
* "layer": {
|
|
* "builtin": ["benches", "drinking_water"],
|
|
* "override": {"minzoom": 12}
