Multi-Dataset Layers
Data Layers are composed of datasets. Most uploads result in layers of a single dataset, but some file formats may lead to layers with multiple datasets. Here are some examples:
- A zip file containing multiple Shapefiles
- A GeoPackage (
.gpkg) containing many layers
- An Excel file with multiple tabs
- A GeoJSON with several different geometry types (points, lines and polygons)
- A KML export from a Google My Maps with many layers.
Working With Datasets
You can see a list of a layer’s datasets in the
Data tab of the Style Editor (see Styling Vector Data to learn more about the Style Editor). For every dataset, you can see its name, an icon of its geometry type (point, line or polygon) and a small table excerpt of its contents.
By clicking on each individual dataset’s overflow menu (three dots in the upper-right corner), you can perform different actions.
