A presentation given at the joint EAC and AARG symposium in Iceland on 25/03/10 by Anthony Beck. This presentation describes electromagnetic approaches to heritage detections

6. EM spectrum and Aerial Photography (Log scale) Traditional aerial photography Tiny Tiny Tiny

7. Multi and Hyperspectral Sensors Dimension and number of recordable wavelengths. There is NO archaeological spectral signature. Allows one to select the portion of the spectrum where there is the most contrast. Hence, an improvement in archaeological detection. Poorly understood outside the visual

8. Mono-spectral (panchromatic) remote sensing 1 Dimension 1 wavelength Limited definition Archaeology is poorly understood outside the visual There is NO archaeological spectral signature.

9. Multi-spectral remote sensing Many dimensions Many wavelengths There is NO archaeological spectral signature. Allows one to select the portion of the spectrum where there is the most contrast. Hence, an improvement in archaeological detection.

10. Hyper-spectral remote sensing Hyper (lots) of dimensions Hyper (lots) of wavelengths. Allows more freedom in spectrum/contrast identification. Hence, an improvement in archaeological detection. Spectral signature allows identification of soil/vegetation There is NO archaeological spectral signature.

11. There is NO archaeological spectral signature

19. First Principals – Archaeological Site Examples Micro-Topographic variations Soil Marks variation in mineralogy and moisture properties Differential Crop Marks constraint on root depth and moisture availability changing crop stress/vigour Proxy Thaw Marks Exploitation of different thermal capacities of objects expressed in the visual component as thaw marks Now you see me Now you dont
