Module geometry_ops 

Geometry operations – spatial computations on geographic geometries

Provides core spatial analysis functions that operate on the engine’s Geometry / GeoCoord types:

• Bounding box – geometry_bbox, Geometry::bbox
• Centroid – geometry_centroid, Geometry::centroid
• Area – polygon_area, ring_area, Geometry::area
• Length – linestring_length, Geometry::length
• Bearing – bearing, initial_bearing
• Interpolation – interpolate_great_circle

All distance/area calculations use the Haversine formula on the WGS-84 sphere (radius 6,378,137 m) for a good balance of speed and accuracy.

Functions

bearing

Initial bearing (forward azimuth) from a to b in degrees (0–360).

geometry_bbox

Compute the geographic bounding box of a geometry.

geometry_centroid

Centroid of a geometry.

initial_bearing

Alias for bearing – initial (forward) azimuth in degrees.

interpolate_great_circle

Interpolate a point along the great-circle path between from and to.

linestring_length

Total length of a linestring in meters (Haversine).

polygon_area

Area of a polygon (exterior minus holes) in square meters.

ring_area

Signed area of a ring on a sphere using the Haversine-based excess formula.
