bbox2extent

Transform a GeoJSON bounding box into an Esri-formatted extent object.

npm install bbox2extent

Usage

var bbox2extent = require('bbox2exent')
var bbox = [100, 0, 105, 1]

var extent = bbox2extent(bbox)

// OR

bbox2extent(bbox, function (err, extent) {
  if (err) throw err

  console.log(extent)
  // {
  //   xmin: 100,
  //   ymin: 0,
  //   xmax: 105,
  //   ymax: 1,
  //   spatialReference: {
  //     wkid: 4326,
  //     latestWkid: 4326
  //   }
  // }
})

Also supports reverse operation (converting an extent to a bounding box) via reverse:

var extent2bbox = require('bbox2extent').reverse
var extent = {
  xmin: -108.9395,
  ymin: 37.084968,
  xmax: -102,
  ymax: 40.8877,
  spatialReference: {
    wkid: 4326,
    latestWkid: 4326
  }
}

var bbox = extent2bbox(extent)
// [ -108.9395, 37.084968, -102, 40.8877 ]

// OR

extent2bbox(extent, function (err, bbox) {
  if (err) throw err

  console.log(bbox)
  // [ -108.9395, 37.084968, -102, 40.8877 ]
})
