Landscape metrics are widely used in remote sensing to evaluate attributes and patterns of targets of interest. To be accepted and easily adopted, a landscape metric must have a consistent theoretical background and , at the same time, be available on an interface which permits to apply this measure without require very specific knowledge about how to implement it in researchers routines of generation and analysis of data. This paper discusses two landscape metrics based on informational entropy that can be used to evaluate the complexity (in sense of heterogeneity) of multispectral images patterns. Also, it is presented CompPlexus, a software designed to facilitate the use of such metrics. The software was tested in an ASTER multispectral sensor image covering the area of Itirapina Ecologic Station (municipality of Itirapina, state of São Paulo, Brazil) and surroundings, where were choosed for the implementation of the measures of complexity areas with more homogeneous patterns and others with heterogeneous patterns. The results had showed that both measures were well-succeeded in differentiating homogeneous and heterogeneous areas. The two metrics also had allowed to locate the position of each pattern within the order-disorder gradient, enabling the evaluation of its level of organization. CompPlexus software was an accurate and easy-to-use tool for the calculation of the complexity of multispectral images patterns.Pages: 6727-673
