+
+# 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">
+
+![](/library/modules/geospatial-analysis/guides/geospatial-center-example.png)
+
+</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          |
