This book discusses about a generic approach of the use of digital camera and light weight unmanned aerial vehicle (UAV) as photogrammetry tool for speeding up the process of acquiring aerial data. There were three experiments has been carried out in this study. All UAV images were processed using photogrammetry technique. There were two main photogrammetric results has been produced in this research such as digital elevation model and digital orthophoto. The results of this study also showed that the differences of DEM and digital orthophoto between both methods are not significant. We also investigate contour line behavior of landslide area and perform calculation of area and volume at the landslide area. The results of the study showed that the integration between digital camera and UAV are capable of producing digital orthophoto and capable of determining the excavated volume of the simulated model. Based on the results, UAV is useful for are many applications such as urban planning, data infrastructure of landslide risk area, forestry mapping, river surveillance and flood surveillance.
