Author: Jia Yu <[email protected]>
AuthorDate: Wed Feb 25 15:49:28 2026 -0800

    Add introductory paragraphs about Geometry and Geography types
    
    - Geometry Functions pages (Spark/Flink/Snowflake): describe planar 2D 
Euclidean model
    - Geography Functions page (Spark): describe spherical geodesic model
    - Cross-link between Geometry and Geography pages in Spark docs

 # Geometry Functions
 
+The `Geometry` type in Sedona represents planar (2D Euclidean) spatial objects 
such as points, lines, and polygons. All coordinates are treated as Cartesian 
(x, y) values, and spatial operations — distance, area, intersection, etc. — 
use flat-plane math.
+
 ## Geometry Constructors
 
 These functions create geometry objects from various textual or binary 
formats, or from coordinate values.

account for the curvature of the Earth.

 # Geography Functions
 
+The `Geography` type in Sedona represents spatial objects on a spherical 
(geodesic) model of the Earth. Unlike the planar 
[Geometry](../Geometry-Functions.md) type, distance, area, and other 
measurements performed on `Geography` objects account for the curvature of the 
Earth and return results in real-world units (e.g., meters). Use `Geography` 
when your data is in longitude/latitude coordinates and you need accurate 
geodesic calculations.

 ## Geography Constructors
 
 These functions create geography objects from various formats.
