Michelle,
I think Vertical Mapper would be able to help you with this problem. By
performing a slope calculation on the DEM file you can easily define areas
that are to steep for a vineyard. In fact you can use the Grid Query on the
results of slope and aspect calculation to determine ideal locations that
are not only at a preferred slope but also the preferred orientation to true
north. These are just two of many tools that can be used for this
application.

Subject: MI: Gradient/slope shading
Hi,
I have a client who wants his elevation data contoured (easy) and
then shaded by gradient. He needs to highlight the areas too steep
for the planting of grapevines. I could use the relief shading to
give a general idea, but was hoping for something a little more
qualitative. I'm running MI 6.0. Any suggestions?
TIA
