I posted this on the Exiftools forum and tried to create login but could not get back into to reply. Phil sent me the code for exiftools to add lat long and elevation. The code worked except that the elevation data was not entered into the images. I have also found out that I need to enter the following paramenters into the images to get my software to mosaic the images: Camera, Camera Model, GpsLatRef, GPsLongRef, DateTimeOriginal, and FocalLength. Will the following code work with the above fields...
