What is TWCC?

TWCC, "The World Coordinate Converter", is an Open Source tool to convert geodetic coordinates in a wide range of reference systems.

Several coordinate conversion tools already exist, however, here is what makes the strength of TWCC:

This tool is intuitive and easy to use.
The possibility to add user-defined systems and the use of an interactive map make it flexible.
No download or special installation is required, you just need to have an Internet connection.
TWCC is compatible with most environments (Mac, Linux, Windows...).
TWCC is completely FREE and licensed under Affero GNU: AGPL

TWCC was created by Clément Ronzon following research and development carried out for GrottoCenter.org.

Special thanks to: Roland Aigner, Alessandro Avaro, Leszek Pawlowicz, Lê Viết Thanh, Ahmed Qatar.

For any questions or suggestions please contact us.
