Remote sensing techniques have played a critical role in the analysis and classification of peatland environments found throughout the world. Due to the vast and remote nature of these landscapes, determining the overall extent as well as performing classification of peatlands is largely a result of the use of aerial imagery. However, there has been limited study on the accuracy of models which have been produced using high resolution aerial imagery captured using drone platforms to accurately interpret the micro topographical formations which serve as key features and important indicators within peatland landscapes. Several transects placed throughout peatland environments were used as a means to capture precise on ground measurements at regular intervals of relative ground, vegetation, and water elevation. These were then used to compare against the corresponding features within Digital Elevation Models produced using high resolution drone imagery in order to determine the accuracy in which they are capable of representing the micro topography within peatland systems. The result will hopefully provide useful information as to how the DEM’s interpret the imagery and to what degree they can be relied upon to provide accurate information about the undulating topography that is typical within these critical environments.
