Inserting and Linking Layers to a Map

Once you have created layers and a map canvas, you can superimpose your geospatial layers onto the map.

---

1. Add Layers to the Map Canvas

1. Open your target map in the Map Editor.
2. Click the settings icon on the right to open the Map Settings floating panel.
3. Select the Layers tab.
4. Click the Add Layers button.
5. In the Layer Pool modal that appears:
   • Search for the layer by name.
   • Click the checkmark/select icon to add the layer to the map.
   • Close the modal.

2. Manage Layer Properties and Order

Under the Layers tab, all linked layers are listed. You can perform the following actions:

Adjust Layer Stack Order (Up/Down Arrows)

• Use the Up and Down arrow buttons beside each layer to adjust its vertical stack order.
• Important: The layer at the top of the list renders on top of layers below it. Place point/icon layers at the top and large polygon layers at the bottom to prevent polygons from blocking point visibility.
• If stack order changes are made, a pending changes warning is displayed.

Focus / Zoom to Layer

• Click on the layer's index number or title in the list. The viewport will automatically fly to the bounding box of that layer's feature geometries.

Show / Hide Layers

• Toggle the visibility state of individual layers to declutter the workspace without unlinking them from the map.

Style and Legend Preview

• Click on the legend icon to preview styles or select custom SLD (Styled Layer Descriptor) files to define fill colors, stroke widths, icons, and conditional styling.

3. Save the Map Layout

After linking and configuring your layers, click the Save Map (or Update) button at the top header bar to persist the layout configuration.

4. Drawing and Editing Features on the Map

You can populate or modify your layer geometries directly on the map canvas using the editor's integrated drawing tools:

1. Select the appropriate layer from your linked list.
2. Activate a tool from the floating drawing toolbar (e.g., Point, Polyline, or Polygon).
3. Draw the geometries directly on the map:
   • Click once to place points or line vertices.
   • Complete shapes (polygons/lines) by double-clicking or clicking the starting vertex.
4. As you draw, a Draft Control Bar will appear at the bottom center of the screen indicating your unsaved shapes.
5. Click View Changes on the bar to inspect attributes or edit metadata values for the new shapes.
6. Click Save Changes within the draft panel to commit the geometry records to your database, or Clear All to discard.
