INTRODUCTION
Landscape metrics based on category, patch, and class representations developed in late 80’s are quantitative spatial measures of landscape pattern exhibiting spatial characteristics (Herold et al., 2005; Acevedo et al., 1996; Li et al., 2005; Goodwin, 2003; Seto and Fragkias, 2005). Spatial metrics bring out the pattern of change in a particular landscape to understand the process (Turner et al., 2001; De Voorde et al., 2011) as spatial metrics behave differently with different pattern of landscape (Li et al., 2005. Uuemaa et al., 2009 provides an account of spatial metrics and their relationships in the landscape planning and other activities. However, there is a need to understand the role of the spatial resolution and its effectiveness while quantifying the landscape dynamics through spatial metrics. The synthesis of effectiveness of spatial resolution on various landscape fragmentation indices, highlight the significant role of the spatial resolution in analysing and understanding landscape patterns (Saura et al., 2000). The integrity of the analysis of landscape depends on the selection of appropriate spatial metrics, the resolution of spatial data apart from careful interpretation of the results (Turner et al., 2001; Li and Wu, 2004).
