# flatlands
[](https://travis-ci.org/cspanring/flatlands)
Transforms a 3D GeoJSON feature geometry to 2D.
## Usage
var flatlands = require('flatlands');
var multipolygon = {
"type": "MultiPolygon",
"coordinates": [
[
[
[102.0, 2.0, 0],
[103.0, 2.0, 0],
[103.0, 3.0, 0],
[102.0, 3.0, 0],
[102.0, 2.0, 0]
]
],
[
[
[100.0, 0.0, 0],
[101.0, 0.0, 0],
[101.0, 1.0, 0],
[100.0, 1.0, 0],
[100.0, 0.0, 0]
],
[
[100.2, 0.2, 0],
[100.8, 0.2, 0],
[100.8, 0.8, 0],
[100.2, 0.8, 0],
[100.2, 0.2, 0]
]
]
]
};
var feature = flatlands(multipolygon);
Returns:
