## 属性

### `vueKey`

- **类型:** `String`
- **可选**
- **非侦听属性**
- **默认值:** `default`
- **描述:** mapgis-web-scene 组件的 ID，当使用多个 mapgis-web-scene 组件时，需要指定该值，来唯一标识 mapgis-web-scene 组件，同时 mapgis-web-scene 插槽中的组件也需要传入相同的 vueKey，让组件知道应该作用于哪一个 mapgis-web-scene。

### `vueIndex`

- **类型:** `Number`
- **可选**
- **非侦听属性**
- **默认值:** `(Math.random() * 100000000).toFixed(0)`随机计算值
- **描述:** 当 mapgis-web-scene 插槽中使用了多个相同组件时，例如多个 mapgis-3d-igs-doc-layer 组件，用来区分组件的标识符。

### `rampColors`

- **类型:** `Array`
- **可选**
- **侦听属性**
- **描述:** 坡向分析角度颜色数组
- **默认值:**

```
[
  { min: 0, max: 60, color: "rgba(244, 67, 54, 0.5)" },
  { min: 60, max: 120, color: "rgba(233, 30, 99, 0.5)" },
  { min: 120, max: 180, color: "rgba(156, 39, 176, 0.5)" },
  { min: 180, max: 240, color: "rgba(255, 235, 59, 0.5)" },
  { min: 240, max: 300, color: "rgba(96, 125, 139, 0.5)" },
  { min: 300, max: 360, color: "rgba(76, 175, 80, 0.5)" }
]
```

## 方法

### `analysis`

- **Description:** 坡向分析

### `remove`

- **Description:** 移除坡向分析对象，移除坡向分析结果。

## 事件

### `@load`

- **Description:** 在 Aspect 加载完毕后发送该事件
- **Payload** 坡向分析对象
