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 ...

Dear all, I have a excel file with xy coordinates for points in the ITRF 2005 format. I am trying to convert the xy coordinates to xy coordinates in the  WGS 84 format. Any ideas how i can go about this or the conversion. Please take a look at the attached excel table of my ITRF 2005 xy Coordinates that i need to convert to xy WGS 84 values. ... View more

I'd like to be able to convert between two Canadian vertical coordinate systems: CGVD28 and CGVD2013.  The staff at Natural Resources Canada have a conversion grid which is in ".byn" format (Canadian Geodetic Survey binary geoid file), but have offered to convert to another format if ArcGIS can't read/use it.  I don't have a handle on the different methods & formats supported, and which would be most appropriate.  Melita Kennedy‌, what can I tell them?  Or - is this file something ESRI already has in hand? ...

Hello! I'm trying to map point from survey plats that are using a state plane coordinate system with 1983 datum with 1993 corrections. With further research it seems they would fall under 1883 HARN, but this is still visually off by 500 yards or so.  Does anyone have another idea of the datum I should use or have familiarity with mapping points with this datum? ...
