Seagrass distribution is a very important index for costal management and protection. Seagrass distribution changes can be used as indexes to analyze the reasons for the changes. In this paper, in situ hyperspectral observation and satellite images of QuickBird, CBERS (China Brazil Earth Resources Satellite data) and Landsat data were used to retrieve bio-optical models and seagrass (Enhalus ac...

In POCS image restoration we consider the case where the prototype images are obtained from the observed image via a predetermined operator, which is the Modified Inverse Filter. A POCS algorithm using the proposed constraints and the limited amplitude constraint is applied to monochrome CBERS-2 satellite band 2 images.

Every spatial unit of human occupation is part of a network structuring an extensive process of urbanization in the Amazon territory. Multi-resolution remote sensing data were used to identify and map human presence and activities in the Sustainable Forest District of Cuiabá-Santarém highway (BR-163), west of Pará, Brazil. The limits of spatial units of human occupation were mapped based on dig...

The Chinese satellites HJ-1 A/B, CBERS-02C and ZY-3 have been recently launched and are considered as the main space platforms on orbit to acquire optical images for monitoring the Earth for various applications in China. The commercially distributed products (Level 1 or 2) of those satellites usually lack sufficient information (about platform, sensor and ephemeris) that is the key to geometri...

Iterative image restoration algorithms can better control the restoration process, but the choice of the relaxation parameters can be an inviable task. We present here a GPbased approach that stabilizes the iterative RAP-2D image restoration algorithm choosing the optimal or quasioptimal relaxation parameters that maximize the improvement signal to noise ratio of phantom images. CBERS-2 CCD ban...
