I have scanned maps georeferenced in custom projection with local datum. I have transformation parameters from the local datum to WGS84. I created a mosaic dataset for the georeferenced maps with custom projection. Now I created another mosaic dataset referenced to first one to create new dataset projected with WGS84 datum. I added "Reproject" function in raster chain functions and set the output projection as WGS84. There is no place to set transformation parameter from local datum to WGS and as a result the new raster dataset is not reprojected properly. Please suggest me how to overcome this issue... Thanks KNWin
