Figure 1: Variation of NDVI in irrigated and non-irrigated areas.
From: Remotely sensed high resolution irrigated area mapping in India for 2000 to 2015

(a,b) Space-time spiral curves (ST-SCs) to study subtle changes in LULC spectral separability for 2001 and 2002 (Julian Day) and (c) Temporal profile of NDVI during 2001 and 2002 for irrigated and non-irrigated areas for seasonal pools of complete season(CMS), first season (FS), intermediate season (IS), and second season (SS).
