- Abstract
The objective of this experiment was to test the validity of multispectral low altitude photography in archaeological surveying. The experiment involved taking multispectral photographs from a UAV of ten plots of land through which the Roman road Iter 34 is thought to have passed. These photographs were used to create georeferenced orthomosaics of the zones and to calculate the NDVI index, anticipating that this index would show differencial growth marks in the crops, inperceptible by other means, which correspond with the Roman road. A comparative analysis of the historical photographs in the geoeuskadi database with the NDVI photographs confirmes that negative stratigraphic features (ditches, wells, pits…) produce positive readings in NDVI whereas positive stratigraphic features (walls, surfaces, demolition deposits) result in negative readings. The Roman road was seen clearly in NDVI in eight of the ten surveyed zones, furthermore two ancient settlements were identified in two of these zones. The experiment can therefore be considered a success and has demonstrated the validity of the method applied to archaeological survey.
