The forest changes every day. Everywhere, at every scale. No one can walk the same woods twice.
But some forest changes are more noticeable, and more important to humans, than others: altering the mood of the landscape, affecting our sense of its health and productivity. Such dramatic changes may be caused by natural agents like fire, flood, animal activity and disease, or by human actions--agriculture, roadbuilding, forestry, urban development. Changes on this scale are often detectable by the remote sensing instruments we now use in large-area forest inventory and monitoring.

With this preface--that change is continuous and ubiquitous, and only a bit of it is observable by any single technology--DNR ForNet offers ChangeView, a look at forest change as seen by the Landsat resource satellite 450 miles above the earth.

First-time visitors to this page are encouraged to have a look at the "Change Detection Methods" link below. The information presented there aids understanding of how our change data sets are derived, and the relative strengths and weaknesses of viewing forest change with this data. Others may simply click on the "Browse ChangeView Data Sets" link to begin an interactive ChangeView session.
