Abstract: In order to improve the technical means of island survey, the UAV technology is introduced into the topographic survey of islands. Taking the large scale mapping of Huzhou island in Dayawan, Huizhou based Swallow-P small fixed wing UAV as an example, this paper summarizes the specific process of external data acquisition and internal data processing, makes DEM and DOM. Precision analysis is provided of measured ground points, the plane position error and elevation error of the large scale mapping results of Huzhou island UAV meet the accuracy requirement of 1:1000 mapping.

Key words: UAV, island surveying and mapping, Swallow-P small fixed wing UAV, large scale mapping, mapping precision, mean square error
