Map comparison over time
Landsat images are acquired from space. Dr. Miller initiated
this work in order to visualize changes to the river system that
have occurred over a 100-year period. This is accomplished by
overlaying the MRC plates (1894) and Landsat 5 images
(1990s) (example on right)

about 350 kb in size. They can be resized and reduced in resolution
for insertion into printed documents.

Dr. David Miller, Department of Geography, SUNY Cortland,
