Return Values

Name	Description
convertFeature	Convert a single item with geometry into a valid GeoJSON Feature
convertList	Convert an array of items into a GeoJSON FeatureCollection

Input Format

Each input item should follow this structure:

• geometry (any)
  An array representing the coordinates. The geometry type is auto-detected based on its structure.
• Additional key-value pairs will be preserved in the GeoJSON properties.

Example Input

const rawData = [
  {
    name: 'Line A',
    geometry: [
      [105.8, 20.9],
      [105.9, 21.0],
    ],
  },
  {
    name: 'Polygon B',
    geometry: [
      [
        [105.8, 20.8],
        [105.9, 20.8],
        [105.9, 20.9],
        [105.8, 20.9],
        [105.8, 20.8],
      ],
    ],
  },
];

Usage

import { useConvertToGeoJSON } from '@hungpvq/shared-file';

const { convertFeature, convertList } = useConvertToGeoJSON();

const feature = convertFeature({
  name: 'Test Line',
  geometry: [
    [105.8, 20.9],
    [105.9, 21.0],
  ],
});

const collection = convertList([
  {
    name: 'Test Line',
    geometry: [
      [105.8, 20.9],
      [105.9, 21.0],
    ],
  },
]);
