ABSTRACT A range of techniques have become established for the visualization and analysis airborne LiDAR elevation data within field archaeology. In this paper we discuss test representing archaeological features in a variety terrains using suite techniques, all available through generic geographical information system or image processing software. These comprise shading constrained colour ramps, slope analysis, hill‐shading, principal component multi‐azimuth local relief models solar...

Abstract Scanning airborne laser altimetry, usually referred to as LiDAR, generates high spatial resolution, accuracy elevation data. The technique has found considerable use in the earth sciences, for example flood modelling and prediction. This paper examines some geoarchaeological applications LiDAR alluviated landscapes. data several lowland river valleys England are examined. potential identifying archaeologically significant geomorphological features through examination of...

AbstractAbstractSatellite remote sensing has seen some use in archaeological research, although its effectiveness been restricted by the low spatial resolution and high cost of available imagery. In 1995 United States declassified 860,000 high-resolution Corona satellite photographs, acquired for intelligence purposes between 1960 1972. offers global coverage with an emphasis on areas strategic significance to States. The imagery released into public domain at acquisition. this paper we...

Now largely levelled multifaceted Islamic cityscape is revealed by aerial satellite imagery.

Abstract Methods for mapping and determining the condition of archaeological resources while they are still underground have been in development nearly half a century. The authors here offer an example from frontiers art: application package remote sensing procedures not only designed to locate sites but model valley deposits which contain cover them. variation success different methods offers guide design evaluation projects on sand gravel terrain everywhere.

Abstract Archaeological applications of airborne lidar topographic data are now well known and documented in the academic literature. Rather less explored by archaeologists potential intensity data. In this paper we explore application for geoarchaeological prospection river valley floors. After briefly considering context archaeological remote sensing valleys, examine some factors influencing record processing steps that may be required to effectively utilize data, before reviewing utility...

This paper outlines the use of geographical information systems for predicting possible implications future climate change (as suggested by General Circulation Models) on archaeological resource selected parts two major British river systems, Trent and Yorkshire Ouse. The effects climatic historic environment are likely to come from both natural 'system' responses, such as increased bank erosion valley floor sedimentation, well human adaptive responses manage impacts change. models described...

Abstract. The orientation of crowdsourced and multi-temporal image datasets presents a challenging task for traditional photogrammetry. Indeed, matching approaches often struggle to find accurate reliable tie points in images that appear significantly different from one another.

ABSTRACT Although river confluences have received geomorphic attention in recent years it is difficult to upscale these studies, so confluence‐dominated reaches are commonly presumed be either: (1) braided; or (2) meandering and characterized by laterally migrating channels. If the geomorphology of a confluence zone considered over longer timescales, changes style need taken into account. This paper uses combination remote sensing techniques (LiDAR, GPR, ER), borehole survey chronometric...

We report gravel of the River Euphrates, capped by basalt that is Ar-Ar dated to ~9 Ma, at Shireen in northern Syria. This gravel, preserved erosion-resistant basalt, allows us for first time reconstruct history this major river during Late Miocene. In response progressive regional surface uplift, Euphrates extended SE ~800 km between early Middle Miocene, when coast was near Kahramanmara? southern Turkey, and Pliocene, it lay western Iraq, east Arabian Platform uplands.
