# TerrainHeightMapTarget

> **TerrainHeightMapTarget** = `object`

Defined in: [render/terrain.ts:30](<https://github.com/maplibre/maplibre-gl-js/blob/538a7680ab16d5cf5a6564ee0ce72a11be14d142/src/render/terrain.ts#L30>)

**`Experimental`**

A float texture for [CustomRenderMethodInput.renderTerrainHeightMap](<https://maplibre.org/maplibre-gl-js/docs/API/type-aliases/CustomRenderMethodInput/#renderterrainheightmap>), such as `RGBA32F`, which needs the `EXT_color_buffer_float` extension to be drawn into. Red holds the elevation in meters, including the terrain exaggeration, alpha is 1 where terrain is loaded and 0 elsewhere, and the first row is the south edge.
