The service provides access to the acquisition, processing, and (in agreement with the applicant) interpretation of high-resolution RGB, multispectral, hyperspectral and thermal infrared images from UAVs for the identification of features of archaeological interest.

The service offers a full suite of UAV-based imaging capabilities, tailored for applicants requiring high-resolution data acquisition and advanced analytical insights. This includes the use of state-of-the-art unmanned aerial vehicles equipped with an array of sensors for the acquisition of high-resolution RGB, multispectral, hyperspectral and thermal infrared imagery. The following is an overview of our technical approach to these four key image types: 1. High-resolution RGB imagery Acquisition: Using UAVs equipped with high-definition cameras, we acquire standard red, green and blue (RGB) images at resolutions sufficient to detect the finest details for precision mapping and visual inspections. Processing: After the flight, the images are merged using sophisticated photogrammetry software to create seamless orthomosaics that provide a complete overview of the site. Further processing steps include geometric corrections to account for UAV movement and optical distortions. 2. Multispectral imaging Acquisition: UAVs are equipped with multispectral sensors that acquire data in specific wavelength bands beyond visible light (vis-nir), providing information on vegetation health, water stress and material identification. Processing: We apply calibration techniques to correct for atmospheric interference and sensor noise. The data is then processed to create high-resolution multi-band orthophotos. Subsequently, various data enhancement techniques are applied (e.g. spectral indices) to extract spectral signatures indicative of archaeological presence proxies. 3. Hyperspectral imaging Acquisition: Equipped with vis-nir hyperspectral sensors (168 bands), UAVs can acquire hundreds of contiguous spectral bands, providing detailed data on the chemical composition of objects and materials on the ground. Processing: The data are then processed to create high-resolution multi-band orthophotos. Subsequently, various data cleaning and enhancement techniques are applied (e.g. spectral indices) to extract spectral signatures indicative of archaeological presence proxies. 4. Thermal infrared imaging Acquisition: Using high-resolution thermal sensors, UAVs capture infrared radiation emitted from various surfaces, which is useful for identifying thermal anomalies. Processing: The thermal data are corrected for variations in ambient temperature and emissivity. High-contrast thermal georeferenced orthophotos are produced to highlight differences in heat retention and emission to identify features of archaeological interest.

The service may be limited by logistical conditions (e.g. no permission to fly in prohibited or dangerous areas) or by scenery/metereological conditions.
