# Geospatial Center
|
|
|
|
Takes a GeoJSON feature and returns the absolute center point.
|
|
|
|
{/*##head##*/}
|
|
|
|
Here is an example of how to use it.
|
|
|
|
<div className="ndl-image-with-background">
|
|
|
|
|
|
|
|
</div>
|
|
|
|
This is what is inside the "Get GeoJSON Feature" funciton node:
|
|
|
|
```js
|
|
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:
|
|
|
|
```js
|
|
const feature = Inputs.Feature;
|
|
const coordinate = feature.geometry.coordinates;
|
|
Outputs.Text = `${coordinate[0]}, ${coordinate[1]}`;
|
|
```
|
|
|
|
## Inputs
|
|
|
|
<div className="ndl-table-35-65">
|
|
|
|
| Data | Description |
|
|
| --------------------------------------------- | -------------------- |
|
|
| <span className="ndl-data">Coordinates</span> | The GeoJSON feature. |
|
|
|
|
</div>
|
|
|
|
## Outputs
|
|
|
|
<div className="ndl-table-35-65">
|
|
|
|
| Data | Description |
|
|
| ---------------------------------------- | ------------------------------------------- |
|
|
| <span className="ndl-data">Center</span> | A GeoJSON feature with the center position. |
|
|
|
|
| Signal | Description |
|
|
| ------------------------------------------- | ----------------------------------------- |
|
|
| <span className="ndl-signal">Changed</span> | Occurs when the Center output is updated. |
