Create a layer / resource (data layer) to delineate an area
A layer allows you to delineate and highlight a territory on the map (department, region, country...).
From Wemap Pro, you can create a layer by importing a GeoJSON format file.
📌 Please note:
- The GeoJSON format is the current standard for describing geographic data and its attributes, being easily integrable into web applications.
- Before importing, make sure that the file complies with the GeoJSON standard and that its size remains reasonable for the web (< 2MB).
- Online tools exist to help you reduce the size of such a file (e.g.: mapshaper.org) or to convert different formats to GeoJSON.
🧩 Create a layer
- Create a new resource: "Create" > "Resource"
- Select "Data Layer"
- Name the resource
- Click on "Import from a file" (in red in the image) or draw with our tools (in blue)
- Customize your layer:
- Click on the relevant area
- Apply the desired configurations from the styling module that opens on the right side of the screen:
- Properties: vary according to the GeoJSON content
- Fill: color and opacity of the fill
- Outline: color, opacity and thickness of the outline stroke
- Click on "Save"
🖇️ Link the layer to a map
Once created, you can then directly link this resource to a map:
- Click on "Link this layer to a map"
- Select the map from the list that appears, then click on "OK".
