COPERNICUS EARTH OBSERVATION FOR CULTURAL HERITAGE

This article summarises the contribution of the European Union's Earth Observation Copernicus Programme, and other satellite-based platforms for cultural heritage applications and highlights the results of some national and European projects conducted in this domain. Even though the Copernicus Programme has recently been introduced for cultural heritage use (i.e., after the second half of this decade), the full, free, and open data policy, known as FFO, has increased the number of relevant applications. Since then, several studies dedicated to cultural heritage monitoring, management, etc., have been presented in the literature. Despite the medium spatial resolution of the radar and optical Sentinel sensors, the high-temporal revisit time of these sensors in combination with other legacy space programmes (e.g., the Landsat space programme) can provide useful information to site-managers, local and regional stakeholders, and other national agencies. Also, new developments in the domain of image processing like the use of big-data earth observation cloud platforms already showcased the potentials for dedicated space-based cultural heritage services. However, this technological shift remains still within the scientific and theoretical research domain. Therefore, much effort is still needed towards the implementation of national policies.
