Working with Data

Unfolded's Map SDK allows you to add, remove or replace existing datasets on the map.

Add a new dataset

Using addDataset(...) function you can pass a new Dataset object that will be added to the map. Layer will be automaticaly created, if not otherwise selected by setting the autoCreateLayers parameter to false.

* Adds a new dataset to the map.
* @param dataset The dataset to add.
* @param options Options applicable when adding a new dataset.
* @returns The dataset that was added.

Remove a dataset

In case we want to remove the added dataset, we just need to pass the id of the dataset to the removeDataset API function:

removeDataset(id: string)

NOTE: Keep in mind that if a dataset is removed, every layer associated with that dataset will be removed too.

  • NameDescription
    id string
    Unique identifier of the dataset

Expanding the sidebar in Unfolded Studio, we can see that the dataset has been removed and along with it the associated layer(s).
