Doneus et al (2008)

•  Purbah Iron age Hillfort, Austria that contains a range of environments and feature types

• Mapped by ground survey in 1960s

• LiDAR scan done in early  spring when deciduous trees were still leafless  and created detail DTM

Findings: Known features confirmed

• Ramparts, ditches, walls that had been previously mapped were confirmed

Findings: new features

• Many very low earthworks were not identified in orginal survey

• Original 56 round barrows could almost doubled

Findings: Clearance pile problem

• LiDAR very effective in parts of the graveyard covered by clearance piles

• These were able to be removed from the DTM and showed barrow traces beneath
