Multirotor UAV photogrammetric offers low cost, flexible manoeuvrings, high resolution images, flying under clouds, easy launch and landing. There are many geometics applications which can be solved using multirotor UAV. Many researchers have studied the problem of low cost mapping using satellite images. Multirotor UAV is able to acquire data within short period of time with low budget. The Multirotor UAV can provide three dimensional coordinates of features and terrain. Multirotor UAV is one of the solutions to obtain fast production of map at the specific area with low cost, less time and less labour needed. In this conference, some previous works on UAV application will discuss such as UAV in slope mapping, UAV in building footprint assessment, UAV in 3D building models, production of DEM using UAV, Multirotor UAV for crack/pothole identification and assessment, building crack detection using multirotor, 3D indoor modelling using UAV's video, multirotor UAV for road design, and UAV on board GPS in positioning determination. These researches involve two different image acquisitions techniques namely aerial and oblique views. There are some considerations that need to be considered during flight mission especially in photogrammetric work for instance UAV calibration, camera calibration, time of image taken, altitude, daylight condition, and etc. In photogrammetric work, the pixel size of the image plays important role to determine the size of the features on the ground. Therefore, the image processing error is based on the pixel error with respect to the metric measurement on the ground. The good ground control points are also required in photogrammetric work in order to obtain reliable photogrammetric products.
