Use this GeoJSON operation to summarize valid geometry for display, indexing, or further spatial processing while retaining the original feature coordinates.

GeoJSON

GeoJSON geometry, feature or collection.

Compute the arithmetic mean (vertex centroid) of every position contained in GeoJSON. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Longitude

Mean longitude of all vertices.

Latitude

Mean latitude of all vertices.

• GeoJSON uses longitude-latitude coordinates in WGS 84 and planar shortcuts can mis-handle the antimeridian, poles, holes, invalid rings, mixed geometries, and large extents. A vertex mean is not always a geometric or geodesic centroid.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Validate geometry, normalize longitude handling, and use a geospatial library with an appropriate projected or geodesic method for precision analysis.

• GeoJSON Bounding Box

  Compute the [west, south, east, north] bounding box enclosing every position in GeoJSON.

• Db Mean Of Readings

  Energetic mean, not arithmetic mean, of two equal-duration sound-level readings.

• Speech Interference Level

  Arithmetic mean of speech-band octave levels at 500, 1000, 2000 and 4000 Hz.
