Use when adding interactive 2D maps to web apps with npm ol 10.11.0 — Map/View, fromLonLat to EPSG:3857, WMS/WMTS/XYZ sources, MVT with featureClass, Draw/Modify/Snap interactions, or debugging blank layers (missing setStyle), offset centers and ol/... module-not-found errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## 安装
```bash
npm install ol
```
```js
import 'ol/ol.css';
import Map from 'ol/Map.js';
import View from 'ol/View.js';
import TileLayer from 'ol/layer/Tile.js';
import OSM from 'ol/source/OSM.js';
const map = new Map({
target: 'map',
layers: [new TileLayer({ source: new OSM() })],
view: new View({ center: [12968000, 4863000], zoom: 10 }) // EPSG:3857
});
```

## 核心概念
| 类 | 作用 |
|----|------|
| `Map` | 顶层容器 |
| `View` | 视图（投影、中心、缩放、旋转） |
| `Layer` | 图层 |
| `Source` | 数据源 |
| `Feature` / `Geometry` | 矢量要素与几何 |
| `Style` | 样式 |
| `Interaction` | 交互 |

## 图层与数据源
### 栅格底图
```js
import XYZ from 'ol/source/XYZ.js';
import TileWMS from 'ol/source/TileWMS.js';

How to install
mdr add znlgis/opengis-skills/openlayers@sha256:ba304defef694237The line at the top of this page pins the label git:20261027.6562616, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
