Abstract
In the last few years a number of light weight multispectral and hyperspectral imagers have appeared on the market. Producers focused on geometrical and radiometric calibration developing reliable instruments. On the other side, there is still need for standardized methods for calibrating and documenting acquired data. This is very necessary mainly for two reasons i) for a collaborative open access scientific effort and ii) for bringing spectral UAV-borne data from research to operationality.
For this purpose we have explored the applicability of a standardized workflow for data acquisition, calibration and documentation. Datasets from multiple instruments have been acquired during different field campaigns. Data have been mosaicked with multiple processing chains. At the same time, field spectrometry data got acquired for calibration purposes. The heterogeneity of such dataset allowed us to test the possibility of a standardized processing chain for data exchange. We proposed then a standardized format for mosaicked, georeferenced and spectrally calibrated data including mandatory metadata. This will make UAV-borne spectral spatial explicit information comparable and usable from the scientific community and end-users.
