Check if a geometry is valid according to OGC standards.

Validity rules (OGC Simple Features specification):

  • Points: Always valid (unless coordinates are NaN/Inf)

  • LineStrings: Must have at least 2 points

  • Rings: Must be closed and have at least 4 points

  • Polygons: Outer ring must be counter-clockwise, inner rings clockwise, rings must not cross each other or touch except at single points

  • MultiPolygons: All constituent polygons must be valid

Parameters:

geometry – Geometric object to check.

Returns:

bool

If called without return_reason (True if the geometry is valid, false otherwise.).

tuple[bool, str]

If called with return_reason=True, returns a tuple where the first element is a boolean indicating validity, and the second element is a string describing the reason for invalidity (empty string if valid).
