Further, the aerial survey also helps in arriving and calculating a possible outbreak of the same in accordance with the other relevant department datas. It also can suggest solutions as the survey can be done continuously and reviewed any number of times in order to arrive at the required solutions by building a DEM(digital elevation model) model which will give the entire topographic 3D layout suggesting on the elvations and the slopes as seen at the site. This helps to:
