abstract = "The Amazon floodplain represents a significant portion of the
worlds wetlands, and participates actively in the carbon cycling
in the region. Due to its large extent, remote sensing is the most
appropriate tool for studying the Amazonian landscape; image
acquisition, however, is highly hindered by the frequent cloud
cover. Medium resolution sensors such as MODIS can overcome this
problem with a larger swath and high frequency of image
acquisition, at the expense of spatial resolution. In the present
study, MODIS images were submitted to an image restoration
algorithm (RESTAU), to assess the capability of this technique for
recovering the spatial detail lost due to the sensor PSF
characteristics. Landsat TM and MODIS Aqua reflectance images were
acquired for a region of the central Amazon during the high water
season. These images were co-registered and the MODIS imagery was
submitted to the restoration algorithm. Two sets of TM and MODIS
images were then analyzed visually and by the calculation of
landscapes indices (i.e. area, shape and patch aggregation). The
results show that image restoration can improve the spatial
information content of MODIS imagery as whole, but gains are more
effective towards area estimations, whereas mapping of shape is
still highly affected by scale even after application of the
algorithm. Overall, it is suggested that use of image restoration
could increase the applicability of MODIS as a tool for area
estimations and continuous monitoring of floodplain cover, while
accurate delineation of shape still requires higher resolution
data to yield acceptable accuracies.",
