Help for TRX
TRX is a coordinate transformation tool that allows you to transform between the North American Datum of 1983 of the Canadian Spatial Reference System (NAD83(CSRS)) and the International Terrestrial Reference Frame (ITRF) realizations; convert coordinates between geographic, Cartesian and mapping projections (UTM, MTM and stereographic); and transform coordinates between epochs using the predicted velocities from the Canadian Velocity Grid.
Several coordinate systems are available: geographic, Cartesian and UTM/MTM/stereographic. All coordinate fields are required in the chosen coordinate system, except heights.
Check the box next to “Epoch Transformation” if you would like to transform your coordinates to a different epoch. Checking the box next to “Interpolate velocities” will interpolate the velocities from the NAD83(CSRS) v7 Velocity Grid - NAD83v70VG. If you don’t check “Interpolate velocities” you can enter your own velocity values.
