/apidoc/8.0/geo:approx-center.xml

Return a point approximating the center of the given region. For a point, this is the point itself. For a circle, it is the center point. For a box, it is the point whose latitude is half-way between the northern and southern limits and whose longitude is half-way between the western and eastern limits. For polygons, complex polygons, and linestrings, an approximate centroid is returned. This approximation is rough, and useful for quick comparisons.

A geospatial region.

Options. The default is ().

Options include:

"box-percent=n"

An integer between 0 and 100 (default is 100) that indicates what percentage of a polygon's bounding box slivers should be used in constructing the approximate centroid. Lower numbers use fewer slivers, giving faster but less accurate results; larger numbers use more slivers, giving slower but more accurate results.

"coordinate-system=wgs84"

Use the WGS84 coordinate system.

"coordinate-system=raw"

Use the raw coordinate system.
