Digital Terrain Model (DTM) is a representation of an earth surface in the threedimensional form. The need to study DTM is to improve its accuracy and efficiency. There are three types ofDTM which are contour lines, grid model and triangulated irregular network (TIN) model which each one has its own characteristics depending on the purposes of the DTM. Total station is often used in determining terrain data for the DTM as it is always practicable (depending upon weather condition) and easier to use except it requires more labour. For this project, DTM is produced based on the selected study area and the generated DTM will be used to simulate cut and fill and certain hydrology simulation. Volume of cut-and-fill is needed to be calculated for the proposed project. To generate DTM, terrain data is acquired through survey using Total Station. The data is used to produce the terrain model using TIN method and calculate the cut-and-fill volume. The model is analysed by comparing the actual terrain with the generated DTM. DTM can represent the terrain as it can describe features very well with introduction ofbreaklines. The cut and fill volume can be calculated and simulated by using the DTM and the simulation of hydrologic flow can be determined by using the DTM. iii
