Creating Reusable Maps and Charts (Snippets)

Snippets are reusable components for maps and charts. You must first create these before you can add them to a dashboard page.

How to Create a Map Snippet

1. In Admin Menu, go to Atlas → Maps → Add Map.

2. Fill in the following:

   • Title – A short name for the map.

   • Optional Description – Explains what the map shows.

   • Dataset – Choose from datasets created in GeoManager.

   • Layer Type – One per snippet (Raster File Layer, Raster Tile Layer, WMS Layer, or Vector Tile Layer).

   • Legend – Already defined in GeoManager when creating the dataset (not in the snippet).

   • Admin Area – Select an admin level and then click on the map to generate the area description.

3. Save the snippet.

Note: Each snippet can only contain one layer.

Block Layout Rules

• Blocks can be arranged in any order.

• When two Map blocks or two Chart blocks appear consecutively and each has a description, the text/title alternates sides automatically:

  • Example: First block → text on the left, map/chart on the right.

  • Next block → text on the right, map/chart on the left.

• This ensures dashboards remain visually balanced and easy to read.

✅ With this setup, you can create rich dashboards combining text, images, tables, maps, and charts—all styled for clarity and interactivity.
