[McIDAS #TEU-219455]: topo map



Hi Kwan,

I have attacked FRMSAVE captures of McIDAS displays of your original
and remapped hi-res topography image.  In both cases, I used the EB
command to manipulate the gray scale enhancement to accentuate the
parts around the Great Lakes.

My observations are:

- the navigation in your original topo image seem to be off

  Compare the map location of the Great Salt Lake and Great Lakes
  with the shorelines indicated by the image.

- the IMGREMAP remapped version of the image seems to faithfully
  replicate what is in the original image

I must say that I have not spent extensive time comparing the images,
so I may be missing something...

Cheers,

Tom
