ZUNIGA-VASQUEZ, José Manuel; AGUIRRE-SALADO, Carlos Arturo  and  POMPA-GARCIA, Marín. Monitoring vegetation using remote sensing time series data: a review of the period 1996-2017 . Rev. Fac. Cienc. Agrar., Univ. Nac. Cuyo [online]. 2020, vol.52, n.1, pp.175-189. ISSN 1853-8665.

Analyzing time series data with remote sensing provides a better understanding of vegetation dynamics, since previous conditions and changes that have occurred over a given period are known. The objective of this paper was to analyze the current status and recent advances in the use of time series data obtained from remote sensors for vegetation monitoring. A systematic search of scientific papers was performed and 167 papers were found, published during the period 1996 to 2017. No significant difference in the amount of years analyzed was found between time series analyzed with a single sensor and those analyzed with a combination of several sensors (i.e. Landsat and SPOT, Landsat and Sentinel, among others). However, the combination of data from different sensors (fusion of images) can improve the quality of the results. Special attention must also be given to the fusion of optical and radar data, since this offers more unique spectral and structural information for land cover and land use assessments.

Keywords : Phenology; Land cover; Analysis of multi-temporal remote sensing; Spatio-temporal analysis; Image fusion.
