DEM of Niagara Region
The following image is a 2 degree by 2 degree area made up of 4 1:250000 USGS DEMs.
The top edge is 44 N, the bottom edge is 42 N, the left edge is 80W and the
right edge is 78W. The four quads used to produce this are Toronto (East),
Toronto (West), Buffalo (East) and Buffalo (West). I was lucky that there
was so much overlap into Canada.
This image shows the DEM for the study area:
