Multispectral UAV research Spiekerbelt Ramele (Raalte), The Netherlands

A multispectral camera was used to study a known archaeological site near Raalte, The Netherlands, to investigate the particular influence of land use practices on archaeological crop mark visibility. The four missions resulted in 24 ortho-mosaics, of which the RGB and the NDVI datasets were selected for further analysis. These eight selected datasets are uploaded here. In the RGB datasets, crop marks were only visible in the August dataset. Crop marks were recognized in the NDVI datasets of June and August.
