APPLICATION OF LAPAN A3 SATELLITE DATA FOR THE IDENTIFICATION OF PADDY FIELDS USING OBJECT BASED IMAGE ANALYSIS (OBIA)

International Journal of Remote Sensing and Earth Sciences (IJReSES), 2021
The role of agriculture is directly related to SDG No.2, which is running a programme until 2030 to reduce national poverty, eradicate hunger by increasing food security and improving nutrition and support sustainable agriculture. Problems faced include the reduction in agricultural land, which results in lower rice production, and the limited ...

Needle- and Canopy-Level Genetic Variation in Scots Pine (<i>Pinus sylvestris</i> L.) Revealed by Hyperspectral Phenotyping Across Sites and Seasons. [PDF]

Evol Appl
ABSTRACT As an essential species across European forests, Scots pine (Pinus sylvestris L.) plays a vital ecological and economic role, yet its physiological variability underlying its adaptive potential remains underexplored. Understanding this intraspecific variability is crucial for uncovering the genetic basis of adaptation.
