Geospatial Center

Takes a GeoJSON feature and returns the absolute center point.

{/##head##/}

Here is an example of how to use it.

This is what is inside the "Get GeoJSON Feature" funciton node:

Outputs.Feature = {
  type: "Feature",
  geometry: {
    type: "LineString",
    coordinates: [
      [102.0, 0.0],
      [103.0, 1.0],
      [104.0, 0.0],
      [105.0, 1.0],
    ],
  },
};

This is what is inside the "Extract Coordinate" function node:

const feature = Inputs.Feature;
const coordinate = feature.geometry.coordinates;
Outputs.Text = `${coordinate[0]}, ${coordinate[1]}`;

Inputs

Data	Description
Coordinates	The GeoJSON feature.

Outputs

Data	Description
Center	A GeoJSON feature with the center position.

Signal	Description
Changed	Occurs when the Center output is updated.
