METHODOLOGY FOR SYSTEMATICAL MAPPING OF ANNUAL CROPS IN MATO GROSSO DO SUL STATE (BRAZIL)

Resumo

This paper presents the preliminary results of a methodology developed for the systematic mapping of annual crops, potentially applicable to the entire country. There are many interests and demands for information referring to agricultural activity worldwide. The execution of yearly crop harvests and its relation to the definition of future markets, the measurement of environmental impacts and, the formulation of public policies for agribusiness, are only some examples of the activities which would benefit from the data generation of cultures in the field. Mapping and monitoring the potential of daily images and of vegetation index from MODIS sensor system, in spite of its limitations due to the spatial resolution of 250m, has not yet been fully explored. The objective of this work is to develop and test a methodological approach based on the spectral/ temporal characteristics of an annual series of images from this sensor and to identify and map annual crops in the State Mato Grosso do Sul, produced with images of medium and high spatial resolution during the year 2007
