GeoRepository - Geodetic Parameter Repository

What is GeoRepository?

GeoRepository™ is a powerful web application and tool for searching and displaying geodetic parameters from a range of data sources and authorities. The underlying database is based on an extendible version of the EPSG dataset and is kept up to date with each EPSG release. All parameters available in the GeoRepository (including custom user records) can be used in geodetic calculations with a high precision Geodetic Calculator.
