Frequently Asked Questions

A geodetic datum is a reference system that defines the origin and orientation of coordinates. WGS84 is the most widely used globally, and SIRGAS2000 in Latin America.

Different countries and projects use different datums. Converting ensures your coordinates are accurate in the required system, avoiding errors of up to 200 meters.

We support 9 datums: WGS84, SIRGAS2000, PSAD56, NAD83, NAD27, ED50, ETRS89, SAD69, and ITRF2014. We use PyProj for precise transformations.
