  • Sensitivity analysis of pansharpening in hyperspectral change detection
    • Authors: Seyd Teymoor Seydi; Mahdi Hasanlou
      Abstract: Change detection (CD) is one of the most important uses of remote sensing, and it plays a key role in many applications. Satellite hyperspectral imagery has a high spectral resolution but low spatial resolution, which results in images with mixed pixels. To improve spatial resolution in hyperspectral images, multiresolution fusion techniques must be used, one which is called pansharpening (PS). This paper investigates the sensitivity and performance of CD methods by fusing Advanced Land Imager and Hyperion datasets based on a PS algorithm. Three different CD algorithms are used here for that purpose: cross-covariance (CC), cross equalization (CE), and principal component analysis (PCA). In addition, Gram-Schmidt (GS), HySure, and PCA are utilized as the PS methods of choice. The CD results obtained from both the original hyperspectral data and from the spatially fused data are compared to reveal the potential of PS in CD applications. Furthermore, the presented procedure also shows that the HySure method in particular yields good results for the CD.

  • An integrated geotechnical database and GIS for 3D subsurface modelling:
           Application to Chennai City, India
    • Authors: Divya Priya B.; G. R. Dodagoudar
      Abstract: Subsurface characterization and clear distinction between layer boundaries in geological profiles are essential for successful completion of engineering projects. Due to limitations in accessing the vast and diverse subsurface information, efficient management of geotechnical data is of special importance. This study presents the methodology of building a digitally formatted and integrated spatial database using geotechnical data and geographic information system (GIS). The development of comprehensive geotechnical (geo)-database involves (1) Collection of borehole data from various reputed sources, (2) Validation of data in terms of accuracy and redundancy and (3) Standardizing and organizing the geotechnical information for incorporating into the database. The database is then integrated with GIS to provide the advantage of visualizing, analysing and interpreting the geotechnical information spatially. In addition, stratigraphic data stored within the spatial database is utilized for constructing three-dimensional (3D) subsurface models. A simplified approach is developed for 3D subsurface modelling with a combination of the Relational database management systems (Microsoft Access), Arc-GIS and Spatial interpolation techniques. The proposed methodology is illustrated using nearly 175 borehole data collected from various projects aimed at providing an exhaustive database and an integrated 3D environment for the Chennai City of south India for better interpretation and decision-making in regard to sustainable urban development. The study also demonstrates the application of the developed subsurface model in evaluating the effectiveness of multichannel analysis of surface wave (MASW) tests to estimate the depth to bedrock, which will be of immense use in foundation studies and in ground response analysis.

  • GIS-based site suitability and vulnerability assessment of
           telecommunication base transceiver station facilities in Ibadan
           metropolis, Nigeria
    • Authors: Suleiman Abdul-Azeez Adegboyega; Ileri Ayo Oyetunji; Ayo Emmanuel Olajuyigbe; Francis A. Adesina
      Pages: 205 - 217
      Abstract: The study assessed GIS capability in siting of base transceiver stations (BTS) to ensuring optimum spatial coverage of signal while minimizing their health impacts. It therefore evaluated the spatial pattern of BTS, determined areas vulnerable to health hazards related to them and identified most suitable locations for siting the BTS in Ibadan metropolis. Digital elevation model, IKONOS, geographic locations of the BTS and administrative map of Ibadan were used. Images and map were georeferenced using ArcGIS 10.2 version. Features such as drainage, road network, buildings among others were extracted from the IKONOS image. Nearest neighbourhood analysis was performed to investigate the nature of the BTS distribution. Buffering analysis was carried out to identify the numbers of buildings at risk of radiation emission from BTS based on National Environmental Standards and Regulation Enforcement Agency (NESREA) 10 m distance regulation. View shed analysis was performed to determine signal strength across the study area. Multi-criteria analysis (MCA) and sensitivity analysis were carried out to generate BTS suitability index maps. The finding showed that BTS distribution pattern was dispersed with z-score of 4.39 and there was less than 1% likelihood that this dispersed pattern could be the result of random chance (P value = 0.01). The study revealed that 934 buildings with 13,387 population were found within 10 m from the BTS and thus vulnerable to possible health hazards of harmful radiation.

  • Low-cost sensors for rapid mapping of cultural heritage: first tests using
           a COTS Steadicamera
    • Authors: Alessio Calantropio; Giacomo Patrucco; Giulia Sammartano; Lorenzo Teppati Losè
      Abstract: One of the last and more pressing requests to the researchers working in the field of Geomatics is to research, validate, and propose new strategies for the rapid mapping of different contexts, with low-cost solutions. The continuous implementation of image-matching algorithms and their use in structure from motion (SfM) software allow using new sensors and implementing new strategies for the production of 3D models starting from an image-based approach. In the last years, another central issue for the researchers has been related with the documentation of cultural heritage (CH) artifacts using different sensors and techniques. In the experience presented in this paper, the attention was focused on these two central aspects: a test of a commercial off-the-shelf (COTS) steadicamera for the rapid 3D documentation of two cultural heritage artifacts was proposed. The two sites chosen to evaluate this mass market sensor were as follows: the Basilica of San Nicola (Tolentino, MC, Marche Region, Central Italy) and the Castello del Valentino (Torino, TO, Piedmont Region, North Italy). The metric products obtained with the Steadicam were compared with more consolidated techniques such as close-range photogrammetry (CRP) and terrestrial laser scanner (TLS). The products derived from the different techniques were then evaluated and compared, and an overall assess of the use of this new solution was made.

  • Development of generalized loss functions for rapid estimation of flood
           damages: a case study in Kelani River basin, Sri Lanka
    • Authors: Akinola Adesuji Komolafe; Srikantha Herath; Ram Avtar
      Abstract: Assessment of infrastructural vulnerability to natural hazards, and subsequent economic loss, can make important contributions to future disaster risk minimization. The recent endeavor is to ascertain and evaluate risk globally, which can provide a framework to identify unique regional vulnerabilities, the mobilization of international investments, and cross-country risk comparison. This would require a concerted effort for the detailed classification of building exposures and vulnerability models. This study presents the design and efficacy of flood-vulnerability models for structural building types. The study uses an empirical approach, with data gathered from survey questionnaire, for direct estimation of flood damages in the Kelani River basin in Sri Lanka. Survey questionnaires were administered in the flood-prone areas of the basin, and depth-damage functions were established for four (4) structural building types that were identified based on the relationship between inundation depths and flood damage ratio. Event-based flood hazards were simulated using the Flo-2D model. Building exposures and densities were derived from remote sensing data, using integrated thematic land cover feature indices and supervised image classification. A modified mathematical loss model was employed to simulate flood damages to each building category for a disastrous flood event in the Kelani River basin. Simulated damages and post-flood survey showed reasonable comparativeness. The models can be employed for loss estimation of future damages and risk-reduction planning for flood disaster in Sri Lanka.

  • A crowdsourcing-based game for land cover validation
    • Authors: Maria Antonia Brovelli; Irene Celino; Andrea Fiano; Monia Elisa Molinari; Vijaycharan Venkatachalam
      Abstract: Land cover datasets are critical environmental information which are becoming increasingly available nowadays as open data. Accuracy of these datasets is key for their use in manifold applications and can be obtained through validation processes, e.g., the intercomparison with other existing land cover data. The results of this procedure usually highlight disagreements between the compared products which should be further analyzed. The presented work has the aim to address this need by proposing an innovative crowdsourcing-based game that engages citizens in validating disagreements between land cover datasets. The game was played during the Free and Open Source Software for Geospatial (FOSS4G) Europe Conference 2015 by the conference participants and allowed to evaluate the disagreements between the GlobeLand30 and the DUSAF land cover datasets on the Como city area (Italy). The results show the feasibility of the proposed approach and the potentiality of gaming in user engagement for land cover validation campaigns.

  • Low-cost warning system for the monitoring of the Corinth Canal
    • Authors: George Hloupis; Vassilis Pagounis; Maria Tsakiri; George Doxastakis; Vangelis Zacharis
      Abstract: This paper presents an in-house developed low-cost triggering design using wireless sensor network (WSN) nodes. A set of corresponding microelectromechanical system (MEMS) sensors (accelerometer and gyroscope) are used along with a radio transmission unit and a microprocessor. In conjunction with the WSN, terrestrial laser scanning (TLS) measurements are used. Specifically, the aim of this work is to introduce a low-cost WSN node with verified repeatability that will raise an initial signal for possible slope change which will be further verified by TLS measurements. The paper demonstrates the deployment of the developed design for a 3-month period in the Corinth Canal in Greece and presents indicative results.

  • Detecting the centring error of geodetic instruments over a ground mark
           through a tribrach-based optical plummet
    • Authors: Εvangelia Lambrou; Konstantinos Nikolitsas
      Abstract: Accurate centring is the primal procedure for the setting and the proper operation of geodetic instruments in order to obtain correct measurements. Different centring means are used through the time from the plumb bob to the laser plummet. The more distributed centring mean, which is examined in this research, is the tribrach with optical plummet; as today, it is used for the setting of a variety of instrumentation as total stations, Global Navigation Satellite System receivers, laser scanners, targets, etc. This paper develops a procedure for the detection and the assessment of the centring accuracy, which occurs over a ground mark trough a tribrach-based optical plummet. The process is based on the rectification of a single image, which is taken through the tribrach eyepiece. About 150 experimental processes were carried out by using different implementation materials for the ground points, as well as by using different targeting options through the tribrach. The resulting centring errors are presented by several diagrams for all the tested combinations in order to define the length and the direction of the centring error vector. The centring error does not exceed 1 mm by all the combinations, while the mean value is about 0.3 mm. Moreover, the direction of the error vectors presents a systematic orientation which probably expresses the observer’s personal equation and skills. The proposed procedure is assessed as reliable and adequate. Further investigation is proposed in order to examine more types of ground targets and the personal influence of the observer.

  • Landslide hazard evaluation and zonation in and around Gimbi town, western
           Ethiopia—a GIS-based statistical approach
    • Authors: Gemechis Chimidi; Tarun Kumar Raghuvanshi; K. V. Suryabhagavan
      Abstract: 2 The main purpose of the present study was to carry out landslide evaluation and zonation in and around Gimbi town in western Ethiopia, located about 440 km from Addis Ababa. This study was conducted following GIS-based statistical method. For hazard evaluation and zonation, nine causative factors viz., slope material, elevation, slope, aspect, curvature, groundwater surface traces, distance to roads, and distance to streams were considered. Data on these causative factors were obtained from secondary maps, digital elevation model, topographical sheets, and through field mapping. Fifty past landslides in the study area were also identified and mapped through field survey and image interpretation. Statistical correlations between each of the causative factors and the past landslides were established in GIS environment to rate the relative contribution of individual factor classes. Thus, by considering ratings for each causative factor subclasses and by assigning suitable weights to each factor, random trial combinations were attempted to produce the landslide hazard zonation map. The results showed that 12.2% of the study area falls in very high hazard, 30.7% in high hazard, 24.3% in moderate hazard, 23.3% in low hazard, and the remaining 9.5% in no hazard zones. Validation of landslide hazard zonation map with past landslides showed that 75% of the past landslides fall within very high and high hazard zones. Thus, the hazard zones depicted can be considered for future planning and development of the study area.

  • Simulating the impact of land use/land cover change and climate
           variability on watershed hydrology in the Upper Brantas basin, Indonesia
    • Authors: Ari Setyorini; Deepak Khare; Santosh M. Pingale
      Abstract: In this study, the impact of land use/land cover (LULC) change and climate variability on hydrological processes was assessed and simulated using the Soil and Water Assessment Tool (SWAT) in the Upper Brantas river basin, Indonesia. The Mann–Kendall (MK) test was used to analyze the spatial variations and temporal trends of the hydro-climatic variables in the basin. The model performance was assessed by using statistical indicators like coefficient of determination (R 2), Nash–Sutcliffe model efficiency (NSE), the ratio of root mean square error to measured standard deviation (RSR), and percentage bias (PBIAS). These were found to be 0.905, 0.997, 0.061, and 5.7 during calibration and 0.916, 0.995, 0.071, and −6.967 during validation, respectively. During 1989–2006, LULC changes were found to be 26.12% forest, converted to 1.3% grassland, 0.03% water, 14.58% urban area, 6.77% mixed plants, and 3.44% rice fields. The integrated effects of the LULC change and climate variability decreased surface runoff, groundwater, lateral flow, and streamflow by −4.44, −2.27, −4.47, and −5.50%, respectively, but evapotranspiration (ET) increased to 0.63%. LULC change increased surface runoff by 20.14%, ET 0.03%, and streamflow 0.29%, but decreased in groundwater by −9.65% and lateral flow by −3.70%. The climate variability decreased surface runoff, groundwater, lateral flow, and streamflow by −19.07, −1.50, −0.53, and −5.78%, respectively. Both climate variability and LULC changes influence the hydrological processes. Therefore, this study recommends that the above two aspects should be taken into consideration for water resources planning and management in the study region in Indonesia.

  • Geoinformatics for assessing the inferences of quantitative drainage
           morphometry of the Narmada Basin in India
    • Authors: Praveen Kumar Rai; Pawan Kumar Chaubey; Kshitij Mohan; Praful Singh
      Abstract: Geoinformatics-based morphological studies play a significant role in planning, designing, and development of river engineering structures. Quantitative morphometric parameters affect catchment streamflow pattern through their influence on concentration time, and geomorphic characteristics of a drainage basins play a vital role in controlling the basin’s hydrology. In the present paper, an effort has been made to assess the inferences of various linear, areal, drainage, and relief aspects of quantitative morphometric characteristics of the Narmada basin and its down (13) and upper watersheds (17) using ASTER DEM data in GIS platform. Total basin area of the Narmada is about 98,796 km2, and it is identified that the study area is an eighth order drainage basin. A total 31,211 stream segments including the Narmada river are identified, and it is clear that the cumulative stream length is higher in first-order streams and decreases as the stream order increases. The bifurcation ratio (Rb) of the Narmada basin is varied from 2 to 9, and it designates that the drainage pattern of the basin has been affected by the structural disturbances. The lowest value of elongation ratio in the basin indicates high relief and steep slope, while highest value specifies relatively plain land with low relief and low slope than other down watersheds. Sinuosity index of Narmada basin is 1.58, which shows that the Narmada river is meandering in nature.

  • Forest canopy height estimation using satellite laser altimetry: a case
           study in the Western Ghats, India
    • Authors: S. M. Ghosh; M. D. Behera
      Abstract: Canopy height is a crucial metric required to quantify the aboveground plant biomass accurately. The study explores the data derived using Light Detection and Ranging (LiDAR) technology from GeoScience Laser Altimeter System (GLAS) aboard Ice, Cloud, and Land Elevation satellite (ICESat) to derive canopy height estimate equations in the tropical forests of the Western Ghats, India. The interpretation of LiDAR waveforms for the purpose of estimating canopy heights is not straightforward, especially over sloping terrain where vegetation and ground are found at comparable heights. Canopy height models are developed using GLAS waveform extent and terrain index, derived from ASTER digital elevation, to counter the effect of topographic relief effects in canopy height estimates over steep terrain. The model was applied to calculate tree heights for whole of the Western Ghats. Results showed that the model can estimate tree heights within the specified height range with an accuracy of more than 90% while using percent overestimation/underestimation method of validation. This shows the effectiveness of the model, especially over steep slopes, also revealing that the models were able to successfully account for the pulse broadening effect. The study highlights the development of a LiDAR-based canopy height model for tropical forest and its ability to yield better canopy height estimates especially over steep slopes.

  • Correlated GNSS and temperature measurements at 10-minute intervals on the
           Severn Suspension Bridge
    • Authors: G. W. Roberts; C. J. Brown; X. Tang
      Abstract: Global Navigation Satellite System (GNSS) data were gathered on the 998-m-long Severn Suspension Bridge main span. The antennas were located on the tops of the four support towers, as well as five locations on the suspension cables; data were gathered at rates of 10 and 20 Hz. In addition, air and steel temperatures were gathered every 10 min. The GNSS data were processed in an On The Fly manner relative to a reference receiver located on a fixed position adjacent to the Bridge, and the resulting dataset was compared to the air and steel temperature data measurements, and correlations reported. Moving average filters that eliminate short-term movements due to wind loading and traffic loading were applied to the GNSS data, resulting in the longer-term deflections due to temperature changes every 10 min. The temperature over the 3 days varied by up to 10 °C, and movements of the order of decimetres were seen. Clear numerical correlations between the changes in temperature and the changes in height are presented when analysed at these 10-min intervals, suggesting that temperature compensation in structural health monitoring systems could be readily applied, resulting in a sustainable structure.

  • Visual inspection of fire-damaged concrete based on terrestrial laser
           scanner data
    • Authors: Wallace Mukupa; Craig Hancock; Gethin Roberts; Khalil Al-Manasir; Huib de Ligt; Zhicong Chen
      Abstract: Visual condition survey and inspection is typically the initial method employed in the assessment of concrete damaged by fire, and it is among the most significant non-destructive testing methods. In spite of visual inspection being simple in principle, it is capable of providing cardinal information about the condition of the fire-damaged structure and act as a basis upon which subsequent and detailed assessment methods can be founded. When concrete is exposed to various elevated temperatures, it undergoes change in its physical characteristics among others, and indicators such as change in surface texture, cracks, spalling and colour change become evident. These indicators of fire-damaged concrete can be assessed using visual inspection methods and further assessed with more advanced methods in a case where detailed investigations are needed. In this study, visual inspection of terrestrial laser scanner data of fire-damaged concrete was investigated by modelling and analysing laser intensity. An analysis of the generated intensity images from laser intensity data has proved useful and valuable in the visual inspection of concrete before and after heating. Furthermore, laser scanner geometric data has been used in the assessment of concrete surface roughness before and after heating.

  • Automation of point cloud processing to increase the deformation
           monitoring accuracy
    • Authors: Ján Erdélyi; Alojz Kopáčik; Imrich Lipták; Peter Kyrinovič
      Abstract: The weather conditions and the loading during operation cause changes in the shape of engineering structures that affect static and dynamic function and reliability of these structures. Due to this fact, geodetic monitoring is an integral part of engineering structure diagnostics and gives important information about the current state (condition) of the structure. Terrestrial laser scanning (TLS) is often used for data acquisition in cases, requiring 3D information with high resolution. Therefore, TLS is used in different surveying applications, even in deformation monitoring of buildings or engineering structures. TLS allows non-contact documentation of the behaviour of the monitored structure. The accuracy of determination of the 3D coordinates of single measured points by currently commercially available laser scanners is several millimetres. The precision can be increased using suitable data processing, when valid assumptions about the scanned surface are available. The paper presents the possibility of deformation monitoring using TLS. To increase the precision of the results, the chosen parts of the monitored structure are approximated by fitting planes to point cloud. In this case, the position of the monitored point (part of structure) is calculated from tens or hundreds of scanned points instead of a single measurement. An application based on software MATLAB®, Displacement_TLS, was developed for automated data processing. It takes only several minutes, as the calculation is executed automatically for all monitored points at once. The proposed method represents fast and simple data processing. Benefits of the proposed method are demonstrated by experimental measurements of different structures and building elements.

  • A comparative evaluation of various models for prediction of displacements
    • Abstract: One of the main subjects of Geodesy is the monitoring of position changes of artificial structures (buildings, dams, bridges etc.). Such position changes can be caused by a variety of reasons such as vehicles for cable bridges and earthquakes. Various mathematical models have been developed in order to monitor and to analyze this phenomenon. This study presents the main models which are used by geodesists for the description of points’ displacements. These are the descriptive models (which are separated into the congruence and the kinematic ones) and the cause-response models (which are separated into the static and the dynamic). Moreover, several models, which are based on time series analysis and are used mainly for the prediction of financial parameters, are referred in parallel. These are the smoothing models, the time series decomposition models, and the ARIMA models. All the abovementioned models are discussed and compared in order to emerge their advantages, disadvantages, and limitations. The goal of this study is to substantiate which of these models could be used with reliability for prediction of displacements. A case study using the most appropriate models is carried out. The experiment deals with the prediction of displacements of a set of permanent GNSS stations. The results proved that the linear kinematic models have the best performance, in comparison with the other examined models.

  • Multi-dimensional and multi-temporal motion estimation of a beam surface
           during dynamic testing using low-frame rate digital cameras
    • Authors: Ivan Detchev; Derek Lichti; Ayman Habib; Mamdouh El-Badry
      Abstract: The combination of digital close-range photogrammetric systems and image processing techniques has been employed in structural health monitoring applications for more than 10 years. The use of off-the-shelf entry level digital single-lens reflex cameras has lately become a suitable choice even for applications requiring sub-millimetre- level precision especially when the involved devices need to be inexpensive. The drawback of such low-cost cameras is in the trade-off between spatial resolution, frame rate, and burst rate—at the highest available spatial resolution, a high frame rate is either not possible or it has a low burst rate. This may be problematic when monitoring a structural component during a dynamic/fatigue test. In order to estimate specimen motion in such a situation, this paper proposes an innovative sinusoidal fitting based on a least squares adjustment. This method simultaneously processes multiple bursts of data in order to synthetically increase the sampling frequency of the system. The input data for the adjustment comes from a full surface modelling procedure based on a newly proposed generalized 3D polynomial. The experimental results include a beam deformation test performed in a structures laboratory. The new sinusoidal fitting method effectively increased the system temporal resolution three-fold, which improved the precision of the derived parameters with up to two orders of magnitude. The root mean square error of the residuals were as good as 26 μm, and the one of the estimated amplitudes from the photogrammetric system versus a set of laser transducers used as control was as small as 43 μm.
