Data shifting FME/ArcGIS


Forum|alt.badge.img
When I bring lat/long data stored in SDE (NAD 83) into FME and run it through all of my transformers associated with doing an AreaOnAreaOverlayer the output appears to shift when I compare it to the original data in ArcMap. Here's a zoomed in area. The light purple color is the FME output. Any ideas why it would not maintain the exact integrity of the input data?

Hi,

 

 

it's difficult to tell without seeing the workspace. Are you perhaps doing some implicit snapping somewhere? Clipping against two almost similar datasets? Rounding of coordinates?

David I had figured it out at the end of yesterday. But you get the best answer because you hit on something I was doing that was causing the issue. I was rounding the coordinates. When I took that transformer out everything overlayed perfectly. Thanks for answering!!!
