Dados digitais do satélite spot e de radiometria de campo no estudo da cultura do feijoeiro (Phaseolus vulgaris L.) irrigado.

Abstract

The paper had the objective to test the application of Spot satellite digital images and radiometer field data, mapping irrigatede areas cultivadet with carioca beans (Phaseolus vulgaris, L.). The derivation of proposed objective was to indentify the cultivated specie among others, to precise the area dimension to subsidize it’s water management. It was verified low correlation between two to temporal, spectral variables and the necessity of field support in mapping irrigated annual crops.
