land cover mapping program for large metropolitan areas.
Demonstrate the ability to monitor urban landscape change on a
regular time frame.
Demonstrate the utility of integrating existing historic maps, remotely
sensed data, and related geographic information to dramatically convey
how the progress of modern urbanization results in profound changes to
