Análise das Alterações do uso e Cobertura do Solo no Município de Centenário-RS com o Auxílio do Sensoriamento Remoto, no Período de 1995-2014
AbstractO presente estudo objetivou analisar as mudanças no uso e cobertura do solo, a partir de imagens Landsat, para verificar a expansão ou retração agrícola no município de Centenário, RS, no período de 1995-2014. Foram utilizadas três imagens de satélite: Landsat 5, sensor TM (Thematic Mapper) relativo aos anos de 1995 e 2005 e Landsat 8 sensor OLI (Operational Land Imager) relativo ao ano de 2014. Com o uso do Software QGIS 2.8 foi realizado o processamento digital das imagens, formação de mosaicos, georreferenciamento e a classificação digital supervisionada, a partir da aquisição de amostras nas imagens. Foram definidas três classes de uso do solo do município: floresta, agricultura e campo. Para o período pesquisado, os resultados apontam uma significativa expansão agrícola e uma consequentemente retração das áreas de floresta e áreas de campo. No período de 1995 à 2014, as áreas agrícolas tiveram um aumento de 18,25%, já as áreas de florestas tiveram uma supressão de 15,61% e as áreas de campo um decréscimo de 2,61%. Nesse sentido, destaca-se que as técnicas de sensoriamento remoto representam uma ferramenta muito útil para a realização de estudos com relação ao uso e cobertura do solo.

Ethical Guidelines for Journal Publication
The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
