( Identification of soil associations with the aid of radar images).Utilizacao de imagens de radar na identificacao de solos sob cerrado.
(1983-01-01)
This study used semicontrolled radar mosaics in the scale 1:250 000. The parameters used in this case were drainage indices as follows: drainage density, frequency of channels and texture ratio. Through statistical analysis ...
Detection of process-related changes in plant patterns at extended spatial scales during early dryland desertification
(Wiley Blackwell Publishing, Inc, 2003-12)
Arid and semiarid shrublands occupy extensive land areas over the world, are susceptible to desertification by anthropic use and can contribute to regional climate change. These prompt the interest to monitor and evaluate ...
Use of digital images to estimate soil moisture
(Revista Brasileira de Engenharia Agrícola e Ambiental, 2019)
Implementación y evaluación de un filtro digital para la transformada wavelet compleja de doble árbol (dt-cwt) aplicada a fusión de imágenes bidimensionales en escala de gris
(2010)
La teledetección aplicada a las geo-ciencias es una herramienta que ofrece un costo relativamente bajo para la detección, clasificación y seguimiento de fenómenos terrestres. Muchos de sus sensores ofrecen imágenes de media ...
Restauração das imagens do satélite CBERS-1 utilizando POCS.
