Thanks for the guidance.The results are correct in the sense that the
transformations are correct in terms of the meters values being returned. My
question is how does this convert to pixel location FROM the data set and then
INTO the image.
In the below code example the bolded values are m

Do you need to write your own code for this?, or could you just use the
gdalwarp utility? (maybe after converting to a format gdal knows).
