1) I created an "Access 2007" accdb file of XY coordiates for 8 points in Database Connections of ArcCatalog 10. I did "ADD Data" of this accdb file to the mxd Map. I also did "ADD Data" to bring a "Google Earth Pro" jpg file of the "the 8 points" area figure to the mxd Map. I did "Zoom To Layer" to these 2 figures on the mxd Map, and then I used the "Control Points" of GeoReferencing to match the 3 outside points. Each time I did the "Control Points" operation, the jpg was rotated and became skewed - see the attached file for details. 2) Several months ago, I used "Excel 2007" xlsx file of the same XY coordiates for the 8 points in the regular folder and brought the same jpg file to my ArcGIS 10. I had no problems to use the "Control Poins" of GeoRefencing to match the 3 outside points - see the second page of the attached file.
Please kindly help and tell me what is wrong in 1) and how to solve the problems of skewed jpg map.
