The create topographic map of hilly and mountainous area has long been a difficult problem for manufacturers in terms of both measurement methods and accuracy requirements. Traditional technologies such as total station method, aerial photography or RTK-GPS ... all have their own advantages and disadvantages. Currently, Unmanned Aerial Vehicles - UAV technology is being applied a lot in the field of mapping and is increasingly improving to have better results in production. However, how accurate is this technology when comparing traditional survey methods for mapping in mountainous areas? So, we have checked its in the 500ha hilly areas in Vietnam. The topographic map was conducted using UAV technology (with Phantom 4 RTK unmanned aircraft) had done the comparison with the checking points generated by RTK-GPS in term of accuracy. The result shows that the map produced by UAV technology matched with the topographic map do by RTK-GPS. Therefore, it can be concluded that the UAV technology can be considered as an alternative technique for production the topographic map.
