Implementação de um sistema web-based para classificação automática de mudanças de uso/cobertura de solo

Abstract

In the last decades, many works, demonstrated the efficiency in the use of high resolution images for the classification of land use and covering changes at regional level. However, it became clear that the use of some techniques on great areas demands prohibitive costs, in a financial point of view as also a computational one. Especially, if we consider limited available resources in less developed areas of Brazil and of the world. The project is inserted in the context of an international effort for the development of a web-based system and includes some areas from Brazil. The main objective is to create technologies validated by the system methodologies, in a way the users use it in a decision-making process. It has as another objective a better understanding concerning the impact done on these areas by the changes of the land covering and use. The proposal here is to make a product that joins automatic routines, based on satellite images available without costs, that can be used in different scales of administration of the territory. It doesn't demand highly specialized technicians to manipulate the web application.
