| Sep 19, 2011 at 18:16 | comment | added | rgwozdz | @mkennedy, Unfortunately esriSRProjCS_WGS1984SphereWebMercator is required. Yes, I am working on doing the conversion in multiple project processes now. A pain, but at least there is a work around. Thanks very much. | |
| Sep 19, 2011 at 18:11 | comment | added | mkennedy | @rgwozdz, Do you have to use esriSRProjCS_WGS1984SphereWebMercator? This maps to 102113. If you're using 10, you could use 102100 aka 3857. This is based on WGS84, not WGS84 auxiliary sphere so you only need a single transformation. Another possibility to do the conversion in two processes. | |
| Sep 19, 2011 at 18:09 | comment | added | mkennedy | @KirkKuykendall, unfortunately, no. The method would be as a gtf file, but they weren't designed to support the composite transformation. Projection engine doesn't support a composite transformation as a separate 'object' so there's no back-door available. | |
| Sep 19, 2011 at 16:10 | comment | added | rgwozdz | Thanks - you pointed out an important problem. In fact, I had the original input and output CS wrong - my sample shape file actually had an in CS of NAD1983SPCS_WASouthFT and my out CS should have been esriSRProjCS_WGS1984SphereWebMercator. I've edited the code above. However, I still have the "Invalid geographic transformation" error. It seems like the gp can't see the new composite geo transformation. | |
