- W2184413210 abstract "Wetlands are complex ecosystems hosting a high diversity of landscape associated with water, soil and vegetation variations. It provides several essential resources for wildlife and human populations and supports a miscellany of aquatic plant species. The Pandeiros Wildlife Sanctuary is a unique wetland ecosystem surrounded by semiarid savannas. It supports large communities of macrophytes and terrestrial plants and stores large quaqntities of organic matter. In this article we propose a methodology for classifying these wetlands using their spectral and textural signature extracted from Ikonos image data. The main plant communities were identified from low altitude photographs acquired with a microlight aircraft. Ground data also complemented these photographic records. Classification trials were made using both spectral and spatial feature (texture) to assess the most appropriate approach. As a result five classes of macrophytes (as dominant specie) and four terrestrial classes were identified with an accuracy of over 80%. Texture data brought a significant improvement to the classification. RESUME:" @default.
