Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Filtering of digital terrain models by 2D Singular Spectrum Analysis

, 2007
Singular Spectrum Analysis (SSA) has been approved as a model-free technique to analyse time series. SSA can solve different problems such as decomposition into a sum of trend, periodicities, and noise, smoothing, and others.

Leaving children behind for cross‐border education: Unveiling the emotional agency of international post‐graduate student mothers

British Educational Research Journal, EarlyView.
Abstract Despite growing interest in the internationalisation of higher education, the experiences of international student parents, particularly international student mothers, remain largely marginalised in research and policy. This paper examines the emotional agency of international student mothers who leave their children behind in their home ...

Evaluation of selected methods for extracting digital terrain models from satellite born digital surface models in urban areas

, 2011
For the generation of 3D city models from satellite stereo imagery beyond the generation of digital surface models (DSM) from stereo data the next crucial step is the separation of urban 3D objects from ground.

Exploring multiple viewshed analysis using terrain features and optimisation techniques

, 2004
The calculation of viewsheds is a routine operation in geographic information systems and is used in a wide range of applications. Many of these involve the siting of features, such as radio masts, which are part of a network and yet the selection of ...

Automated DEM extraction in digital aerial photogrammetry: precisions and validation for mass movement monitoring

Annals of Geophysics, 2005
Automated procedures for photogrammetric image processing and Digital Elevation Models (DEM) extraction yield high precision terrain models in a short time, reducing manual editing; their accuracy is strictly related to image quality and ...
