Good Afternoon,

I'm interested to know if anyone can tell me what NTM-derived digital data
is and if there is a web site available that may have such data that
can be downloaded.

Don't have a clue with that one.

Also coes anyone know of sites that archive time frames of land use and
cover data for the years 40's through 90's ?

Try http://www.tnris.state.tx.us. Although we have lots of information going
back to the 40's, most of it is not in digital form prior to the 80's. We
are trying to move it.
