TRX Coordinate Transformation Tool
TRX is a free online coordinate transformation tool provided by Natural Resources Canada that combines and replaces GSRUG (Geodetic Survey Routine UTM/TM Geographic) and TRNOBS (Transformation & Observations) utilities. It allows users to transform coordinate values between different geometric reference frames such as NAD83 and ITRF, epochs and coordinate systems such as geographic, cartesian and local projections systems like MTM and sterographic.
Several coordinate systems such as geographic, cartesian and UTM / MTM / (UTM, MTM, stereographic and custom projections) are available to use. All coordinate fields are required in the chosen coordinate system, except heights. The free tool is provided by the Canadian Geodetic Survey of Natural Resources Canada and is subject to the Canadian Open Government Licence.
Using TRX to transform your coordinates is pretty simple, simply select the origin reference frame and epoch, as well as the origin coordinates system. Then select your destination reference frame and epoch, as well as the destination coordinates system. Then click the Calculate button. If you want to have the horizontal and vertical velocities outputted then be sure to check the Epoch Transformation box found above the origin coordinates section.
The TRX application is also available as a stand-alone desktop application that you can download free and run on your PC or laptop.
