geo-identify-position-format

Identifies a few common geometry position formats.

Install

npm install geo-identify-position-format

Use

var geoid = require('geo-identify-position-format');

geoid.identify(positions)

returns one of:

• geoid.FLAT_ARRAY
• geoid.ARRAY_OF_ARRAYS
• geoid.TYPED_ARRAY
• geoid.ARRAY_OF_TYPED_ARRAYS
• geoid.NDARRAY

when positions has one of the following formats:

• Flat arrays [1,2,3,4,5,6]
• Array of arrays [[1,2,3], [4,5,6]]
• Array of TypedArrays [new Float32Array([1,2,3]), new Float32Array([4,5,6])]
• TypedArray new Float32Array([1,2,3,4,5,6])
• ndarray ndarray(new Float32Array([1,2,3,4,5,6]))

If positions does not have one of the previously listed formats, geoid.identify will throw an error.
