## L7 地理空间数据可视分析引擎
|
||||
|
||||
L7 是由蚂蚁金服 AntV 数据可视化团队推出的基于 WebGL 的开源大规模地理空间数据可视分析开发框架。L7 中的 L 代表 Location，7 代表世界七大洲，寓意能为全球位置数据提供可视分析的能力。L7 以图形符号学为理论基础，将抽象复杂的空间数据转化成 2D、3D 符号，通过颜色、大小、体积、纹理等视觉变量实现丰富的可视化表达。

## L7 2.0 Roadmap
|
||||
|
||||
|
||||
|
||||
## Development
|
||||
|
||||
使用 Yarn Workspace 完成依赖安装以及各包之间的 link 工作：
|
||||
```bash
|
||||
yarn install
|
||||
```
|
||||
|
||||
开发模式：
|
||||
```bash
|
||||
yarn watch
|
||||
```
|
||||
|
||||
运行 Demo
|
||||
```bash
|
||||
yarn storybook
|
||||
```
|
||||
|
||||
代替 `git commit` 提交：
|
||||
```bash
|
||||
yarn commit
|
||||
```
|
||||
|
||||
## view doc example
|
||||
|
||||
```bash
|
||||
npm start
|
||||
```
|
||||
visit http://localhost:8000/
|
||||
|
||||
## Add Package
|
||||
|
||||
add new package：
|
||||
```bash
|
||||
lerna create my-pack -y
|
||||
```
|
||||
|
||||
将 ui-lib 作为 my-pack 的依赖：
|
||||
```bash
|
||||
yarn workspace my-pack add ui-lib/1.0.0
|
||||
```
|
||||
|
||||
将 lodash 添加为所有 package 的依赖(不包含root）
|
||||
```bash
|
||||
yarn workspaces run add lodash
|
||||
```
|
||||
|
||||
将 typescript 设置为 root 的开发依赖
|
||||
```bash
|
||||
yarn add -W -D typescript jest
|
||||
```

### 简介
|
||||
|
||||
热力图图层，包含三种类型的，
|
||||
- 方格热力图
|
||||
|
||||
将一组点数据按照等大小的正方形网格进行聚合，一个正方形网格代表网格内所有点的统计值。方格热力图特点以方格网布局。
|
||||
|
||||
- 六边形热力图
|
||||
|
||||
将一组点数据按照等大小的六边形网格进行聚合，一个六边形网格代表网格内所有点的统计值。蜂窝热力图特点以六边形热力图网格布局
|
||||
|
||||
- 经典热力图
|
||||
|
||||
|
||||
|
||||
⚠️ 网格热力图和蜂窝热力图需要对数据聚合处理，使用之前需要在source方法设置数据聚合方法
|
||||
|
||||
### source
|
||||
|
||||
热力图只支持点数据作为数据源
|
||||
|
||||
布局方法 通过source的 tansforms属性配置
|
||||
|
||||
- type 数据聚合类型 grid、hexagon
|
||||
- size 网格半径 单位 米
|
||||
- field 聚合字段
|
||||
- method 聚合方法 count,max,min,sum,mean5个统计维度
|
||||
|
||||
```javascript
|
||||
|
||||
layer.source(data, {
|
||||
parser: {
|
||||
type: 'csv',
|
||||
x: 'lng',
|
||||
y: 'lat'
|
||||
},
|
||||
transforms:[
|
||||
{
|
||||
type: 'grid',
|
||||
size: 15000,
|
||||
field:'v',
|
||||
method:'sum'
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### shape
|
||||
|
||||
不同类型热力图shape支持
|
||||
|
||||
| | 2D | 3d |
|
||||
| --- | --- | --- |
|
||||
| 网格格热力图 | circle,triangle,square,heaxgon | cylinder,triangleColumn,hexagonColum,squareColumn |
|
||||
| 蜂窝热力图 | circle,triangle,square,heaxgon | circle,triangle,square,heaxgon |
|
||||
| 普通热力图 | heatmap | heatmap |
|
||||
|
||||
|
||||
热力图布局下只shape方法只支持常量的可视化。
|
||||
|
||||
```javascript
|
||||
HeatmapLayer.shape('square');
|
||||
HeatmapLayer.shape('hexagon');
|
||||
// 默认类型可以不设置
|
||||
```
|
||||
|
||||
### size
|
||||
当前版本 shape 为grid，hexagon不需要设置 size 映射
|
||||
|
||||
default 类型需要设置size映射 详细参数见[Size](https://www.yuque.com/antv/l7/layer#size)
|
||||
|
||||
**size(field,values) **
|
||||
|
||||
- field: 热力图权重字段
|
||||
- values: 数据映射区间 热力图显示 [0, 1] 效果最佳
|
||||
|
||||
```javascript
|
||||
HeatmapLayer.size ('field', [0, 1])
|
||||
```
|
||||
|
||||
|
||||
### color
|
||||
default heatMap 类型不需设置 color映射
|
||||
|
||||
color 配置项同 [**color**](https://www.yuque.com/antv/l7/layer#color)
|
||||
|
||||
|
||||
|
||||
### style
|
||||
|
||||
grid hexagon 可以通过style 设置透明度
|
||||
|
||||
default热力图需要通过style配置参数热力图参数
|
||||
|
||||
- intensity 全局热力权重 推荐权重范围 1-5
|
||||
- radius 热力半径，单位像素
|
||||
- rampColors 色带参数
|
||||
- colors 颜色数组
|
||||
- positions 数据区间
|
||||
|
||||
```javascript
|
||||
HeatmapLayer.style({
|
||||
intensity: 3,
|
||||
radius: 20,
|
||||
rampColors: {

### shape
|
||||
|
||||
线图层支持4种 shape
|
||||
|
||||
- line 绘制路径图，
|
||||
- arc 绘制弧线 通过贝塞尔曲线算法技术弧线
|
||||
- greatcircle 大圆航线，地图两个点的最近距离不是两个点连线，而是大圆航线
|
||||
- arc3d 3d弧线地图 3D视角
|
||||
|
||||
⚠️ 弧线只需要设置起始点坐标即可
|
||||
|
||||
```
|
||||
new LineLayer()
|
||||

```
|

### size
|
||||
|
||||
线图层 可以设置高度
|
||||
|
||||
- size 类型为number 则表示 line的宽度
|
||||
- size 类型为 [number , number] 分别表示宽度和高度
|
||||
|

```javascript

||||
|
||||

# 使用方法
|
||||
|
||||
L7 提供三种使用方式：CDN、Submodule 以及 React 组件。
|
||||
|
||||
## 通过 CDN 使用
|
||||
|
||||
首先在 `<head>` 中引入 L7 CDN 版本的 JS 和 CSS 文件：
|
||||
```html
|
||||
<head>
|
||||
<script src='https://api.l7/v2.0.0-beta/l7.js'></script>
|
||||
<link href='https://api.l7/v2.0.0-beta/l7.css' rel='stylesheet' />
|
||||
</head>
|
||||
```
|
||||
|
||||
如果使用 Mapbox，还需要额外引入 Mapbox 的 JS 和 CSS 文件，这一步可以参考 [Mapbox 文档](https://docs.mapbox.com/mapbox-gl-js/overview/#quickstart)：
|
||||
```html
|
||||
<head>
|
||||
<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v1.5.0/mapbox-gl.js'></script>
|
||||
<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v1.5.0/mapbox-gl.css' rel='stylesheet' />
|
||||
<!-- 上一步引入的 L7 JS 和 CSS -->
|
||||
</head>
|
||||
```
|
||||
⚠️高德采用异步加载，因此不需要引入任何额外静态文件。
|
||||
|
||||
然后在 `<body>` 中定义一个容器并设置一个 `id`。通过全局 `L7` 这个命名空间可以获取场景 `L7.Scene` 和图层 `L7.PolygonLayer`：
|
||||
⚠️需要获取高德或者 Mapbox 的使用 token 并传入 `L7.Scene` 的构造函数，获取方式如下：
|
||||
* 高德地图开发者 Key [申请方法](https://lbs.amap.com/dev/key/)
|
||||
* [Mapbox Access Tokens](https://docs.mapbox.com/help/how-mapbox-works/access-tokens/#creating-and-managing-access-tokens)
|
||||
|
||||
## 通过 Submodule 使用
|
||||
|
||||
首先通过 `npm/yarn` 安装 `@l7/scene` 和 `@l7/layers`：
|
||||
```bash
|
||||
npm install --save @l7/scene @l7/layers
|
||||
// or
|
||||
yarn add @l7/scene @l7/layers
|
||||
```
|
||||
|
||||
然后就可以使用其中包含的场景和各类图层：
|
||||
```typescript
|
||||
import { Scene } from '@l7/scene';
|
||||
import { PolygonLayer } from '@l7/layers';
|
||||
|
||||
(async function() {
|
||||
// 获取数据
|
||||
const response = await fetch(
|
||||
'https://gw.alipayobjects.com/os/basement_prod/d2e0e930-fd44-4fca-8872-c1037b0fee7b.json',
|
||||
);
|
||||
const data = await response.json();
|
||||
|
||||
// 创建场景
|
||||
const scene = new Scene({
|
||||
center: [110.19382669582967, 50.258134],
|
||||
id: 'map',
|
||||
pitch: 0,
|
||||
style: 'dark',
|
||||
type: 'amap',
|
||||
zoom: 3,
|
||||
token: 'pg.xxx', // 高德或者 Mapbox 的 token
|
||||
});
|
||||
|
||||
// 创建图层
|
||||
const layer = new PolygonLayer({});
|
||||
layer
|
||||
.source(data)
|
||||
.size('name', [0, 10000, 50000, 30000, 100000])
|
||||
.color('name', [
|
||||
'#2E8AE6',
|
||||
'#69D1AB',
|
||||
'#DAF291',
|
||||
'#FFD591',
|
||||
'#FF7A45',
|
||||
'#CF1D49',
|
||||
])
|
||||
.shape('fill')
|
||||
.style({
|
||||
opacity: 0.8,
|
||||
});
|
||||
|
||||
// 添加图层到场景中
|
||||
scene.addLayer(layer);
|
||||
|
||||
// 渲染场景
|
||||
scene.render();
|
||||
})();
|
||||
```
|
||||
|
||||
最后在 `<head>` 中引入 L7 CDN 版本的 CSS 文件：
|
||||
```html
|
||||
<head>
|
||||
<link href='https://api.l7/v2.0.0-beta/l7.css' rel='stylesheet' />
|
||||
</head>
|
||||
```
|
||||
|
||||
L7 目前的文档都通过这种方式使用，可以参考项目中的 stories：
|
||||
* [高德地图](https://github.com/antvis/L7/blob/next/stories/MapAdaptor/components/AMap.tsx)
|
||||
* [Mapbox](https://github.com/antvis/L7/blob/next/stories/MapAdaptor/components/Mapbox.tsx)
|
||||
|
||||
|
||||
## [WIP] React
|
||||
|
||||
React 组件待开发，目前可以暂时以 Submodule 方式使用：
|
||||
```tsx
|
||||
import { Scene } from '@l7/scene';
|
||||
