High-resolution topography for Digital Terrain Model (DTM) in Keller Peninsula, Maritime Antarctica
Abstract High resolution topography (HRT) surveys is an important tool to model landscapes, especially in zones subjected to strong environmental changes, such as Antarctica, where landform is highly influenced by cryoclasty and permafrost melting. The aim of this work was to obtain a high accurate...
