The problem of landslides that occur in West Java continues to increase every year, one of the landslides that claimed many lives is a landslide that occurred in Kampung Cimapag, Sukabumi Regency. Changes in land use change and steep topographic conditions are factors that have caused this disaster to occur. This problem will continue if there is no in-depth study related to factors causing landslides. The purpose of this study is to map in detail the topographic conditions of Cimapag Village, so that an analysis of topographic conditions can be carried out and then an analysis of the potential hazards of aftershocks. The problem solving method used in this research is mapping with photogrammetric techniques using a drone vehicle, or Unmanned Aerial Vehicle (UAV) Photogrammetry. The results of this study are orthophoto maps with a spatial resolution of 8.11 cm, and produce several products such as orthophoto maps, three-dimensional models, and Digital Elevation Models. Based on the measurement of the slope of the landslide, the value of the slope is 51.78% with the condition of the slope which is not covered by vegetation. These conditions can potentially occur aftershocks.
