Hi,
I wanted to use the coordinate frame rotation method to transform MANUALLY WGS84 to NAD83 CSRS. Some of the parameters to do so are given in meter (dx, dy and dz). I tried many times to do this transformation using the formulas for this method. But no result concords with the values given by ArcGIS when I do this transformation using this software.
could you please tell me if I have to transform some parameters in other units before applying the formulas.
lat/long of my point in WGS84: LAT=47.562060394000000 LONG=-52.740740910000000
formulas:
M=(1+dS*10^-6)
XT=M*(1*Xs-Rz*Ys+Ry*Zs)+dx
YT=M*(Rz*Xs+1*Ys-Rx*Zs)+dy
ZT=M*(-Ry*Xs+Rx*Ys+1*Zs)+dz
parameters: dx=0.991000000, dy=-1.907200000, dz=-0.512900000, rx (second)=0.02578991, ry (second)=0.00965010, rz (second)=0.01165994, ds=0.000000000
Expected (ARCGIS) - From WGS84 to NAD83_CSRS:
LAT=47.562050544
LONG=-52.740746617
Thanks for your help
