Mapeamento e análise do uso e ocupação do solo na bacia do rio vieira no município de Montes Claros/MG

With the use of geotechnology is possible to identify and quantify changes in physical space over time. In the present study sought to assess changes in the use and occupation of the ground in Vieira River basin between a timeline of three years. For the verification of changes in Vieira River Basin between 2009 and 2012, was used the mapping of 2009, created by Leite et al. (2011) and the same methodological basis for the elaboration of mapping for the year 2012, with supervised classification, pixel for pixel, maximum likelihood algorithm (MAXVER) and 99.99% acceptance threshold. The following classes are defined; urban area, agricultural culture, mining, water resources, forestry, grazing, natural vegetation and others. Among the changes suffered by this basin in the range of three years, one can notice increase of land use for mining and forestry activity, in addition to continuous use for grazing, once the region's agriculture as an economic activity.
