Module spatial 

Structs

LoraPoint

A 2D or 3D point, either Cartesian or WGS-84 Geographic.

Enums

PointKeyFamily

Which coordinate family the caller used.

Constants

CRS_CARTESIAN

Canonical CRS name strings as understood by point().

CRS_CARTESIAN_3D

CRS_WGS84_2D

CRS_WGS84_3D

SRID_CARTESIAN

SRID_CARTESIAN_3D

SRID_WGS84

SRID_WGS84_3D

Functions

cartesian_distance

Euclidean distance between two Cartesian points (2D or 3D).

haversine_distance

Haversine distance in metres between two WGS-84 geographic points.

point_distance

Distance between two points — dispatches to Euclidean or Haversine depending on SRID. Returns None if the SRIDs don’t match, which also covers the 2D-vs-3D mismatch since the dimension is baked into the SRID (7203 vs 9157, 4326 vs 4979).

resolve_srid

Resolve a final SRID from the optional user-provided crs, srid, plus the detected key family and dimensionality.

srid_from_crs_name

Normalise a CRS name string to its canonical SRID.

srid_is_3d

srid_is_geographic

srid_is_supported

Recognise a bare SRID as one of the four supported values.
