About GeoXY

GeoXY is a free, browser-based geodetic platform for surveyors, civil engineers, and GIS professionals.

Who builds GeoXY

GeoXY is created and maintained by Mohamed Sobhy Ismail, a technical manager and civil engineer based in Cairo, Egypt. It grew out of day-to-day work on engineering projects where coordinate and datum conversions — Ain el Abd 1970, Egypt's belt systems, Nahrwan, KUDAMS, and others — were repeatedly done by hand in spreadsheets.

The goal is simple: put accurate, transparent geodetic tooling in the browser so it works the same on a desk or on a phone in the field, with no install and no server round-trip for core conversions.
