En los últimos 25 años, la Argentina alcanzó una relevante serie de hitos tecnológicos al diseñar y construir satélites propios, entre ellos, cuatro en cooperación con la nasa, dos que llevan la antena de radar más grande ...
Characterisation of functional-trait dynamics at high spatial resolution in a Mediterranean forest from sentinel-2 and ground-truth data
(MDPI, 2018-12)
The characterisation of functional-trait dynamics of vegetation from remotely sensed data complements the structural characterisation of ecosystems. In this study we characterised for the first time the spatial heterogeneity ...
