On the other hand, the large collected data, when the GPR system is mounted on a moving vehicle, is difficult to process. Given that processing is conducted by qualified practitioners, it is a key to obtain software tools that allow for accurate thickness measurements and fast processing times. In this paper, an easy to use and intuitive tool for pavement thickness measurement is presented. Exploiting the power of C++ programming language and the Qt framework advantages for developing applications with graphic interface, a simple and intuitive tool for a qualified worker is implemented in order to reduce the processing times and to give information at the earliest possible moment. Furthermore, the software provides a visualization application for the georeferencing of the field GPR data by using additional GPS (Global Positioning System) data. Given that the GPR acquisition software can connect to an external GPS for trace tagging, NMEA synchronization was used in this case. If the connection is set properly, the GPR acquisition software creates a number of files in order to get the GPR traces paired with a GGA sentence. After post-processing, all the traces are referenced to a SBET (Smooth Best Estimated Trajectory).","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130327894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This resource is at threat from development and climate change. Only a small percentage of the identified wetlands in North West Europe have been studied with regard to their depth, stratigraphic architecture and the heritage assets they contain. The focus of this research is to improve understanding of how GPR can be used to tackle this problem. Data has been collected from wetland sites known to be associated with archaeological remains. The GPR results have been validated by boreholes subjected to geoarchaeological and geochemical analysis. The results show that GPR can obtain meaningful results in a range of wetland sediments. The depth is limited depending on the sediment type, water content and water chemistry with a depth of 80ns (2.5m) imaged clearly in fen peat using a 200MHz antenna greatly reduced in clay rich sediments. Archaeological monuments and structures are detectable. Identification and mapping of local stratigraphic units important for setting archaeological sites in a landscape and sedimentary context has also been possible. Interpretation of GPR surveys is greatly improved with the collection and analysis of boreholes.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These projects integrate remote-sensing techniques, geophysics (in particular the ground-penetrating radar - GPR - technique), field-walking, and, geoarchaeological excavations both on macro- (km) and mesoscale (m). As well known, if the traditional destructive tools applied to archaeology generally produce a reconstruction of the ancient past in an irreversible way, the results of NDT instruments seem to go in the opposite direction by giving geo-archaeological information in a quick and non-destructive way, but not always clear. Tn this paper we will show the results especially from GPR surveys, because, in spite of other NDT approaches, GPR has resulted the most efficient one due to its rapidity, accuracy, and resolution. Nevertheless, this work demonstrates that, sometimes it is possible to have lack of information to interpret the correct archaeological landscape evolution just based on remote sensing data. A multidisciplinary approach, starting from a NDT data at a macro-scale till a minimally invasive tests (coring, pits, etc.) at meso-scale, has the potential to clarify preliminary assumptions, and give the right direction to the research project.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123479922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

GPR is most commonly applied in sandy coastal settings to determine the environmental evolution of an area. Several studies have used GPR to investigate the impact of storms through the identification of erosional scarps and very few have used GPR to investigate coastal overwash deposits. Here we present GPR profiles collected from a swale near the west coast of Phra Thong Island, Thailand, a key site where the 2004 Indian Ocean Tsunami and three earlier tsunamis deposited 5 to 20 cm thick, sandy deposits that are easily distinguished by intervening organic mud layers. We utilised 100, 500 and 1000 MHz antennas to image the spatial continuity of the sand-mud interface. The 100 MHz antennas demarcate the contact between the swale and underlying beach ridge stratigraphy, whereas the 1000 MHz antennas were poor at resolving the swale's internal stratigraphy. The 500 MHz antennas resolved the tsunami sand-organic mud contacts as evidenced from auger cores collected along the profiles. The 500 MHz profiles show where the 2004 tsunami partially scoured the back of the beach ridge and deposited sands over the back-beach environment. Our results confirm the utility of GPR to characterise sandy overwash deposits in muddy environments, which has applications for a range of coastal and fluvial settings around the globe.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121197263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Encountering unmarked burials, or establishing locations free from burials, can be a problem. This case study reports an investigation of the area around a family burial plot in the cemetery of a church in rural Derbyshire, England, where a number of burials have taken place but where detailed records of the locations and numbers of graves were uncertain. The cemetery investigated is associated with a church which has existed since at least the 1200's, and the burial plot investigated has had a number of known burials from the 1800's onwards. The age of the cemetery and the lack of records meant that the exact details of the locations, depths and size of graves in the plot were unknown. The investigation used a GSSI SIR-2000 system with 900MHz and 400MHz antennas to successfully identify and confirm the location of a number of buried graves in the plot, at depths up to approximately 1.5m. This paper describes the challenges faced during the investigation, providing recommendations on appropriate site methodology and conclusions on appropriate data processing and presentation techniques.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114211068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, tomographic approaches are based on a suitable modeling of the electromagnetic scattering phenomenon, which is required to cast the underlying inverse problem. In particular, the non-linearity of the inverse problem entails that solution methods are extremely sensitive to modeling errors and, even worse, are prone to the occurrence of false solutions, that is, estimates of the unknown function that match the data but are different from the ground truth. As such, most of the effective applications of tomographic GPR are so far concerned with linearized inversion approaches, which are based on simple models and are indeed free from false solutions. However, they can only provide information on the location of buried targets and not on their electromagnetic features. In this paper, we present a new tomographic approach that, being based on a “scenario specific” linearized model arising from a suitable preprocessing of the measured data, allows to both achieve information on the electromagnetic features and avoid occurrence of false solutions. The method is presented and numerically assessed for the case of cross-borehole GPR surveys.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131742374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
