[EN] The invention relates to a method of differentiating uses of soil and quantifying vegetative cover by means of remote sensing with aerial photography. The invention is suitable for use in agriculture and, more specifically, by enterprises providing technical assistance in the field of agriculture or the environment or in relation to public or private agro-environmental audits. The invention essentially consists in using remote sensing techniques in order to perform precise, large-scale monitoring of agricultural producers using conservation techniques with ligneous crops. Said techniques consist in maintaining vegetative covers between windrows of trees in order to reduce erosion of the soil, which is one of the most serious environmental problems in the Mediterranean basin. The inventive method provides a highly-precise tool having the following three objectives, namely: 1) to determine the existence or absence of vegetative covers; 2) to estimate the percentage of cover occupied by said vegetative covers on farm land; and 3) to determine entitlement or non-entitlement to aid/subsidies in accordance with the regulations of various different public authorities, which are intended to promote the implementation of conservation techniques.
[ES] Procedimiento para la discriminación de usos de suelo y la cuantificación de cubierta vegetal mediante teledetección con fotografía aérea. El presente procedimiento tiene aplicación en Agricultura, y más concretamente en Empresas de Asistencia Técnica Agraria o Medioambiental o bien en Auditorías Agroambientales Públicas o Privadas. Principalmente consiste en utilizar técnicas de teledetección para realizar un seguimiento preciso y a gran escala de los productores agrícolas que utilicen técnicas de conservación en cultivos leñosos. Éstas consisten en el mantenimiento de cubiertas vegetales entre las hileras de árboles para reducir la erosión del suelo, uno de los problemas agroambientales más importantes de la Cuenca Mediterránea. El procedimiento objeto de la patente facilitaría una herramienta de alta precisión que tendría tres objetivos: 1) determinar la existencia o no de cubiertas vegetales, 2) estimar el porcentaje de cobertura que éstas ocupan en las fincas agrícolas, y 3) determinar el derecho o no a la percepción de ayudas / subvenciones estipuladas según los reglamentos de varias administraciones públicas y destinadas a favorecer la implantación de las técnicas de conservación.
