coordinate_transform

Reproject a WKT geometry from one SRID to another. Both SRIDs must be in the curated allowlist: 4326 (WGS84), 3857 (Web Mercator), 3003/3004 (Gauss-Boaga Italy), 4258 (ETRS89), 6707/6708 (RDN2008 / Italy), 32632/32633 (UTM 32N / 33N).

Use cases

Convert legacy Italian Gauss-Boaga (EPSG:3003) coordinates to WGS84 for mapping.
Reproject an OMI polygon (often shipped in 32632) into 4326 to match other tools.
Send Web Mercator (3857) bounds back to a Leaflet/MapLibre client.

Arguments

Name	Type	Required	Description
geom_wkt	string	required	Input WKT.
from_srid	integer	required	Source SRID (allowlist).
to_srid	integer	required	Target SRID (allowlist).
