+
+Generate elevation profile image
+--------------------------------
+
+Creates an elevation profile image from a list of map layers and an optional terrain layer.
+
+Parameters

+   :header-rows: 1
+   :widths: 20 20 20 40
+
+   * - Label
+     - Name
+     - Type
+     - Description
+   * - **Profile curve**
+     - ``CURVE``
+     - [vector: line]
+     - The line layer representing the profile curve along which the elevation profile will be generated
+   * - **Map layers**
+     - ``MAP_LAYERS``
+     - [multipleLayers]
+     - The list of map layers to include in the elevation profile
+   * - **Chart width (in pixels)**
+     - ``WIDTH``
+     - [number]
+
+       Default: 400
+
+       Minimum value: 0
+     - The width of the output chart in pixels.
+   * - **Chart height (in pixels)**
+     - ``HEIGHT``
+     - [number]
+
+       Default: 300
+
+       Minimum value: 0
+     - The height of the output chart in pixels.
+   * - **Terrain layer**
+
+       Optional
+     - ``TERRAIN_LAYER``
+     - [raster]
+     - A terrain layer (e.g., DEM) to use for elevation data. If not provided, elevation data will be derived from the map layers.
