Subject: Canadian border photo images
I'm looking for a graphic index for a series of "color image maps" done
by the USGS (in cojunction with US Customs) along the Canadian border,
back in 1977. They are 7.5' 1:25,000 images, like a quadrangle map, but
centered along the border from Massena, NY, to Richford, VT. Basically,
orthophoto quads derived from B&W and infrared aerials and printed in
green and brown. No contours, but place names and UTM grid is
overprinted.
Does anyone know of an index sheet for these? USGS put out an index
sheet for the US/Mexico border images that were done at the same time.
There aren't that many, so I guess I could draw my own if necessary.
Thanks,
Mark
