FAQ
What is WKB?
WKB (Well-Known Binary) is a compact binary geometry format commonly used by PostGIS and spatial databases. It’s often shown as a hex string or base64 string.
What is EWKB?
EWKB is an extended WKB variant that can include an SRID (coordinate reference system). If your input is EWKB, this viewer detects and displays the SRID.
