## data

Currently, the data formats supported by L7 are:`GeoJSON`，`CSV`，`JSON`，`Image`。

- `GeoJSON`Supports all standard spatial data formats such as points, lines, and areas.

- `CSV`Supports data types such as points, line segments, and arcs.

- `JSON`Supports simple point, line, and area data types, but does not support multi-point, multi-line, and multi-area data formats.

### GeoJSON

`GeoJSON`Is a format for encoding various geographic data structures. GeoJSON objects can represent geometries, features, or feature collections. GeoJSON supports the following geometry types: point, line, polygon, multipoint, multiline, polygon, and geometry collection. Features in GeoJSON include a geometric object and other attributes, and feature collections represent a series of features.

```json
{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [110.478515625, 32.76880048488168],
            [117.68554687499999, 32.76880048488168],
            [117.68554687499999, 37.64903402157866]
          ]
        ]
      }
    }
  ]
}
```
