# `t`

```elixir
@type t() :: %Common.Message.TerrainData{
  data: [XMAVLink.Types.int16_t()],
  grid_spacing: XMAVLink.Types.uint16_t(),
  gridbit: XMAVLink.Types.uint8_t(),
  lat: XMAVLink.Types.int32_t(),
  lon: XMAVLink.Types.int32_t()
}
```

Terrain data sent from GCS. The lat/lon and grid_spacing must be the same as a lat/lon from a TERRAIN_REQUEST. See terrain protocol docs: https://mavlink.io/en/services/terrain.html
