摘要:Detecting and locating greenhouses in south-east of Spain is very important for politicians and other persons who may take decisions about management of natural resources and who must design agricultural development plans. Agriculture is one of more important economic activities in this zone, and till now, development and disposition of new greenhouses was uncontrolled. In this paper, we present a methodology to detect greenhouses from 1.5 m pixel size QuickBird image, based in Artificial Neural Network algorithm. Thanks to the information introduced as training sites, we "teach" to the mathematical model to classify the image consider ing its radiometric and wavelet texture properties. This assessment is known as training, and the algorithm to obtain it, back-propagation. Classification accuracy was evaluated using multi-source data, comparing results including and no-including wavelet texture analysis. We conclude that some texture analysis can not improve classification accuracy but if one choose correctly parameters and texture model, it can become better. Actually we are working on automatic detection and actualization of greenhouses distributions
