For what you are describing the TopoQuads would be OK, but you might want to
look at the following link for free aerial photos:
http://kymartian.ky.gov/doqq/Apparently Kentucky has a reasonably good library of aerial images, as does
our state, Maine. We use those for showing streams and fencelines om recon
sheets. The home site:
http://kygeonet.ky.gov/ seems like it might be
excellent for downloading other datasets for use in preliminary drawings.
You may find ready made contours there. The aerial photos tend to come in
at the right scale if you also download the worldfile associated with the
photo. Also they tend to show fencelines, buildings, roads, utility
corridors sometimes even individual utility poles depending on quality.
This is great for plotting legals and overlaying them. Again, we do the
same thing for our worksheets. You can download MRSID image files or jpeg
images and worldfiles at the site above. Any questions feel free to ask.
