Abstract :
Over the past few years, reconstructed scatterometer imagery has been used for equatorial forest inventory. This paper presents results of a project to monitor large-area changes in the natural Brazilian landscape which is apparent between 1978 and 1996. The 1978 image originates from the Seasat-A scatterometer (SASS), whereas the 1996 image is reconstructed from recent 1996 NASA (NSCAT) imagery
