Two-level model for land degradation mapping on multispectral satellite imagery

Two-level model for land degradation mapping on multispectral satellite imagery of low and medium spatial resolution is shown. First level model applies several different thematic classifications of source multispectral images, e.g. vegetation change, soil erosion etc. Second level gives data fusion of specific thematic classifications of the first level into final thematic map to improve accuracy and reliability of wing to joint interpretation. Proposed model will be useful for information support systems to provide land management

Using Web resources while teaching foreign languages

The wealth of the information available on the Web can afford teachers and learners to get an access to language learning resources like never before. The World Wide Web expands the classroom context and provided access to current, up-to-date materials from the country or countries of the target language, offering learners and teachers a great amount of materials in different modes, bringing the foreign culture and language to life and making it more tangible. Online journals, newspapers and magazines provide authentic materials for language learners while teachers can find lesson plans and ideas, exercises, assessment tools and other materials for using in their classes
