Understanding the urban dynamics and evolution of spatial patterns of urbanization along the gradients (of 1 km incrementing radii) is illustrated in figure 3. The approach involves understanding decadal land use and built-up dynamics,  (ii) zone wise (based on directions)  gradient analysis (with 1 km gradients),  (iii) analyses of spatial patterns of urbanisation through computation of metrics in in each gradient, (iv) Comparing spatial metrics to understand  trajectories of urbanization at local levels, (v) analyses of overall patterns of urbanisation through Principal Component Analysis to bring out the intra and inter-regional similarities and variability of urban growth.
