Adding and managing layers

Each map is built from layers. This page covers adding layers to a map, controlling which layers show, and configuring how each layer looks.

Adding layers to a map

1. Open the map and click Layers in the sidebar.
2. Click + Add layer.
3. Click Add next to each layer you want. The dialog stays open so you can add several layers in one go; each one is marked Added as it lands on the map.
4. Click Done when you're finished.

The list shows everything from your organization's Data section that isn't already on the map: feature layers and connected external services. If the list is empty, create a feature layer or connect a service in Data first.

The Layers panel

Open Layers in the map sidebar to see every layer on the map. Layers higher in the list draw on top.

• Show or hide a layer: click the eye icon. This only changes what you see. Your choices are remembered for this map on this browser and don't affect anyone else. To change what others see when they open the map, use default visibility instead.
• Reorder layers: drag the grip handle to change the drawing order (editors only).
• Style and properties: click the gear icon to open the layer editor (see below).
• Remove a layer: click the x (editors only). You'll be asked to confirm. Removing a layer discards its style and popup setup for this map, but the underlying data is kept and the layer can be added back later.

Layer style and properties

Click the gear icon on a layer row to open the layer editor.

Symbology

Choose how the layer's features are drawn:

• Single symbol: every feature uses the same symbol.
• Categorized: features are styled by the values of a text, dropdown, or multi-select field, with a symbol per value.
• Graduated: features are colored along a ramp based on a numeric field.

When you categorize a multi-select field, a feature can hold several values at once, so the categories become a priority list: the feature takes the symbol of the topmost matching category. Reorder categories with the up/down arrows to set which value wins.

Changes preview live on the map as you make them, but they are not saved until you click Save style. If you close the editor with unsaved changes, you're asked whether to discard them; discarding snaps the map back to the last saved style.

Visible zoom range

Set a zoom band to show the layer only at certain zoom levels, for example hiding a dense point layer until viewers zoom in past city level. Outside the band the layer hides automatically. Leave both ends as Any for no limit.

Popup

Choose which attribute fields appear in the popup when someone points at a feature, and in what order. Drag fields to reorder them and use the checkboxes to show or hide individual fields, then click Save popup.

By default every field shows in schema order, and new fields added to the layer's schema appear in popups automatically. The full attribute panel always shows every field, in the order you set here.

Filter

The Filter tab limits which features of the layer are drawn on this map, for example showing only trees with a trunk diameter over 10 cm. You can also apply a temporary filter just for yourself. See Filtering features.

Default visibility

The Visible when the map opens checkbox sets whether the layer starts visible or hidden for everyone who opens the map, including viewers of a public link. Use it to include optional reference layers that are off by default. This setting saves immediately.

Anyone can still show or hide the layer for themselves in the Layers panel.
