UPSCALING AND VALIDATION OF RTK-DIRECT GEOREFERENCED UAV-BASED RGB IMAGE DATA WITH PLANET IMAGERY USING POLYGON GRIDS FOR PASTURE MONITORING

The TephATA database comprises morphological, geochemical, and chronological data of volcanic ash layers from the Atacama Desert. The dataset provides a basis for identifying the same volcanic ash layers in different sediment deposits and to determine their stratigraphic and chronological relationships. Known ages of volcanic eruptions can be transferred among equivalent ash layers, which allows dating of sediments. Also ash dispersal and the volcanic history of a region can be studied.
