Doc

1. Clone remote codes to local, then use the yarn command to install the project in local directory.

2. Execute mkdir dist in the project root directory (do not need to do this if the directory already exists).

3. Rewrite the latitude and longitude range in index.js file where you want to crawl the data (upper left corner & bottom right corner).

const lnglatRange = [
  [118.01307678222655, 24.596143627409358],
  [118.15830230712889, 24.452462684995407],
];

4. Execute yarn start in the project root directory, the retrieved data will be stored in the dist directory as a .geojson file.

说明

1. clone 代码到本地,根目录使用 yarn 命令安装项目

2. 项目根目录下执行 mkdir dist(若目录已存在则不需要)

3. 修改 index.js 文件中需要爬取的坐标经纬度范围:

// 需要爬取的经纬度范围(左上角、右下角)
const lnglatRange = [
  [118.01307678222655, 24.596143627409358],
  [118.15830230712889, 24.452462684995407],
];

4. 项目根目录下执行 yarn start,爬取的 .geojson 数据将存储到 dist 目录下
