The study analyzes seven topographic parameters namely absolute relief, relative relief, dissection index, slope, aspect, drainage density and ruggedness index, for better understanding of local relief characteristics with some observation of structural landscape pattern.The advanced application of Remote Sensing (RS) and Geographic Information System (GIS) techniques have lead to estimation of above parameters based on Digital Elevation model and satellite imagery. The entire Morobe province of Papua New Guinea has been selected for this study. The study area is bounded within 145° 30′ to 148° E longitude and 5° to 8° S latitude. Higher the value of dissection index is calculated over the region, indicating larger undulation and instability of the terrain. The topographic ruggedness index also indicates the extent of instability of land surface and it is found northern and south-centre part of the province.
