The Roman villa in Oberlienz-Lesendorf, Austria. GPR Survey and Archaeological Interpretation
In 2007, the remains of an extended Roman villa rustica, only partially known from old excavations, were detected through high-resolution GPR measurements at Oberlienz-Lesendorf (Austria). The archaeological prospection was conducted by the Vienna Institute for Archaeological Science (VIAS) in collaboration with the Department of Archaeologies of Innsbruck University and ZAMG Archeo Prospections. Despite the important discovery, the Roman villa i…
Lost and found
The introduction of airborne laser scanning (ALS) technology in the Mediterranean region over the past decade has significantly increased opportunities for archaeological research. Archaeological remote sensing has proven to be a versatile tool with numerous applications beyond simple site mapping. One approach is the large-scale interpretation of ALS data, which allows for the analysis of the stratigraphic information contained within the data. …
History and Archaeology in Discourse on the Dernberg–Reconstructing the Historical Landscape of a Medieval Motte-and-Bailey Castle and Deserted Village
Investigating deserted medieval castles and villages in remote rural areas paired with a scarcity of meaningful written sources is a challenging task that can be significantly enhanced by the use of non-invasive archaeological prospection methods. Furthermore, the interpolation of stratigraphic relationships among maps by analysing paths and field boundaries, as performed by Klaus Schwarz in the 1980s, can also contribute significantly. Thus, in …
Autograf—AUTomated Orthorectification of GRAFfiti Photos
Admired and despised, created and destroyed, legal and illegal: Contemporary graffiti are polarising, and not everybody agrees to label them as cultural heritage. However, if one is among the steadily increasing number of heritage professionals and academics that value these short-lived creations, their digital documentation can be considered a part of our legacy to future generations. To document the geometric and spectral properties of a graffi…
Multi-Trace Coherence Mapping and Data Fusion for Improved GPR Imaging
Usually only GPR reflection amplitudes are imaged, while GPR data contain far more information.– Multi-trace GPR coherency visualisations offer new insights into structures otherwise hardly visible.– Image fusing permits the combined display of different GPR data attributes (amplitude and coherency)
The Rich and the Hard-Working
Large-area high-resolution magnetic and GPR surveys of whole Roman villa sites in Noricum, where no such settlements have been excavated in total so far.– Using image fusion to combine magnetometry and GPR data from low contrast soils to optimise data quality
Surfaces from the Visual Past
Historic aerial images are invaluable sources of aid to archaeological research. Often collected with large-format photogrammetric quality cameras, these images are potential archives of multidimensional data that can be used to recover information about historic landscapes that have been lost to modern development. However, a lack of camera information for many historic images coupled with physical degradation of their media has often made it di…
Integration of Complementary Archaeological Prospection Data from a Late Iron Age Settlement at Vesterager—Denmark
Pixel versus object — A comparison of strategies for the semi-automated mapping of archaeological features using airborne laser scanning data
BRDF and its Impact on Aerial Archaeological Photography
Despite the arguments in favour of oblique photographs acquired during observer‐directed reconnaissance sorties, many aerial archaeologists have extracted much valuable information from verticals generated during total coverage mapping surveys. This paper looks at one of these arguments: the issue of anisotropic surface reflectance, which is responsible for the allegedly superior rendering of (mainly) vegetation and shadow marks when observed fro…
Mesh Is More—Using All Geometric Dimensions for the Archaeological Analysis and Interpretative Mapping of 3D Surfaces
New ways to extract archaeological information from hyperspectral pixels
Airborne remote sensing for archaeology is the discipline that encompasses the study of archaeological remains using data collected from an airborne platform by means of digital or film-based aerial photography, airborne laser scanning, hyperspectral imaging etc. So far, airborne hyperspectral scanning or – more accurately – airborne imaging spectroscopy (AIS) has occupied only a very small niche in the field of archaeological remote sensing: bes…
The discovery of the school of gladiators at Carnuntum, Austria
Sophisticated techniques of archaeological survey, including airborne imaging spectroscopy, electromagnetic induction and ground-penetrating radar, are opening up new horizons in the non-invasive exploration of archaeological sites. One location where they have yielded spectacular results is Carnuntum in Austria, on the south bank of the Danube, capital of the key Roman province of Pannonia. Excavations in the late nineteenth and twentieth centur…
Airborne laser bathymetry – detecting and recording submerged archaeological sites from the air
The Stonehenge Hidden Landscapes Project
Over the centuries many archaeologists have investigated the site of Stonehenge and we now know a great deal about the phasing and nature of the site. However, the area around the henge, while containing many symbolic and ritual elements, is curiously ‘blank’. The Stonehenge Hidden Landscapes Project aims to place the site and its development through time within a landscape context using fast and accurate ground‐based geophysical techniques. The …

Computer Vision‐based Orthophoto Mapping of Complex Archaeological Sites
Ancient quarries are intriguing archaeological sites, but their detailed recording is complex. This paper presents a cost‐effective approach to mapping of the Roman quarry site of Pitaranha (Portugal–Spain). First, aerial photographs were acquired using a radio‐controlled digital reflex camera attached to a Helikite, which allowed the acquisition of the necessary low‐altitude aerial footage in the very unstable wind conditions above the quarry. U…
Three-dimensional recording of archaeological remains in the Altai Mountains
In the course of their research campaign in Siberia, Ghent University archaeologists have developed a simple and cost effective method for the rapid 3D imaging of rock art, standing stelae and surface monuments. Their procedure will undoubtedly have a big role to play in archaeological research in advance of the oil pipeline expected soon
Taking computer vision aloft – archaeological three‐dimensional reconstructions from aerial photographs with photoscan
Structure from motion (SFM) algorithms are known for their ability to reconstruct a sparse point cloud of scenes that were imaged by a series of overlapping photographs. When complemented by stereo‐matching algorithms, detailed three‐dimensional models can be built from such photograph collections in a fully automated way. Since 2010, a computer vision software package called PhotoScan has been available from the Russian manufacturer AgiSoft LLC.…
Balancing on the Borderline – a Low‐cost Approach to Visualize the Red‐edge Shift for the Benefit of Aerial Archaeology
Scientists from different research disciplines have provided essential information that relates the biophysical characteristics of plants to their spectral reflectance. This fundamental understanding has facilitated the development of various non‐destructive sensing methods for detecting vegetation stresses, monitoring plant growth and calculating crop yield. Aerial archaeologists flying in small aeroplanes have only partially exploited this know…

Helikite aerial photography – a versatile means of unmanned, radio controlled, low‐altitude aerial archaeology
During the past 100 years, various devices have been developed and applied in order to acquire archaeologically useful aerial imagery from low altitudes (e.g. balloons, kites, poles). This paper introduces Helikite aerial photography (HAP), a new form of close range aerial photography suitable for site or defined area photography, based on a camera suspended from a Helikite: a combination of both a helium balloon and kite wings. By largely overco…
Providing an archaeological bird's‐eye view – an overall picture of ground‐based means to execute low‐altitude aerial photography (Laap) in Archaeology
Since the beginning of aerial photography, researchers have used all kinds of devices ranging from pigeons, kites, poles and balloons to rockets in order to take cameras aloft and remotely gather aerial data needed for a combination of research goals. To date, many of these unmanned devices are still used, mainly to gather archaeologically relevant information from relatively low altitudes, enabling so‐called low‐altitude aerial photography (LAAP…
