Abstract
Drone acquired imagery was used as the basis for a geographic information system (GIS) of ecological restoration projects in Northland including Waipoua Forest and Whirinaki areas in Northland. Advantages included convenience in the conduct of surveys, ease of use in flight planning, very high-resolution imagery, lower costs compared to satellite or plane surveys and the ability to conduct repeat flights readily. Limits include battery endurance, weather conditions, terrain, access to survey sites and the processing required.
Results included orthomapped products, digital surface models, classification of the ground and story maps. Outputs also include 3D models that allow different viewpoints of the landscape and provide much-needed information on areas that are not readily accessible and where satellite images are not updated regularly nor are of sufficiently high resolution.
