Airborne light detection and ranging (LiDAR) surveying technology plays an important role in road design, and it is increasingly implemented in the design stage. The ability of LiDAR as a remote sensing technology to be used in non-accessible places (i.e., hilly terrain, steep slope) makes it a powerful tool, and it has the potential to provide benefits that simplify existing design processes for designers and practitioners. This paper reviews the application of airborne LiDAR in road design and factors including items from the perceived usefulness of technology. The context of the future direction of LiDAR technology is highlighted in civil engineering road design, roadway inspection and as-built documentation. The implementation of this technology is expected to assist the end-users in developing more manageable planning for road construction and thus to ensure the usage of LiDAR technology is enhanced from time to time, especially in Malaysia.

UTILIZATION OF LIDAR (LIGHT DETECTION AND RANGING) TO MEASURE SHALLOW WATER DEPTH. Understanding on seabed characteristics such as the topography, composition and habitat conditions was very important to provide information not only for shipping activities, conservation, management and planning activities, but also for research activities with accurate bathymetry data. Accurate bathymetric data can be obtained from hydrographic surveys and remote sensing technology analysis. The hydrographic survey is used to obtain bathymetry data by applying singlebeam echosounder (SBES) and multibeam echosounder (MBES). At a depth of <15m (shallow water) was difficult to carry out an acoustic survey. At present there is one remote sensing technology that can be used to support hydrographic surveys namely Bathymetric LIDAR (Light Detection and Ranging). LIDAR was able to detect objects on land and waters due to being flown by a vehicle. Wide LIDAR sweep makes data acquisition faster and more effective than acoustic noise. Therefore, LIDAR was an alternative to obtain depth data, especially in coastal areas with a depth of less than 50 m.

LIDAR (Light Detection and Ranging) is a remote sensing technology that measures distance by illuminating a target with a laser and analysing the reflected light LIDAR is largely used in geography geology forestry and other sectors In agriculture LIDAR is used for creating topographic maps of fields and for crop mapping in orchards and vineyards The objective of this study was to test two LIDAR systems for their ability to obtain useful canopy characteristics within an apple orchard The two LIDAR systems included a SICK LMS20030106 and a SICK LMS51110100 PRO SR which mainly differ by the laser beam divergence the number of signal returns the range and the resolution as well as frequency values Methods involved mounting each LIDAR sidebyside in conjunction with a RTK GPS and computer system One orchard line was scanned on both sides in order to obtain a full scan at three differing ground levels 60 cm 115 cm and 120 cm As expected the captured data indicate differing resolutions and further analysis is being administered to determine canopy characteristics between the two LIDAR models such as percent open space and porosity This technology could be used for improving agrichemical application in orchards

Remote sensing technology enables detecting, acquiring, and recording certain information about objects and locations from distances relative to their geographic locations. Airborne Lidar bathymetry (ALB) is an active, non-imaging, remote sensing technology for measuring the depths of shallow and relatively transparent water bodies using light beams from an airborne platform. In this study, we acquired Lidar datasets using near-infrared and visible (green) wavelength with the Leica Airborne Hydrography AB Chiroptera-I system over the Devils River basin of southwestern Texas. Devils River is a highly groundwater-dependent stream that flows 150 km from source springs to Lake Amistad on the lower Rio Grande. To improve spatially distributed stream bathymetry in aquatic habitats of species of state and federal conservation interest, we conducted supplementary water-depth observations using other remote sensing technologies integrated with the airborne Lidar datasets. Ground penetrating radar (GPR) mapped the river bottom where vegetation impeded other active sensors in attaining depth measurements. We confirmed the accuracy of bathymetric Lidar datasets with a differential global positioning system (GPS) and compared the findings to sonar and GPR measurements. The study revealed that seamless bathymetric and geomorphic mapping of karst environments in complex settings (e.g., aquatic vegetation, entrained air bubbles, riparian zone obstructions) require the integration of a variety of terrestrial and remotely operated survey methods. We apply this approach to Devils River of Texas. However, the methods are applicable to similar streams globally.

Sea Bed

Submarine pipelines must be designed to resist wave and current induced hydrodynamic forces especially in and near the surf zone. They are buried as protection against forces in the surf zone, however this procedure is not always feasible particularly on a movable sea bed. For this reason the characteristics of the sediment transport on the construction site of beaches should be investigated. In this investigation, the application of the remote sensing method is introduced in order to determine and observe the coastal morphology, so that submarine pipelines may be protected against undesirable seabed movement.

It is expected that, by 2050, people aged over 60 in 65 nations will constitute 30% of the total population. Healthy aging is at the top of the world political agenda as a possible means for hindering the collapse of care systems. How can ICT/sensing technology meet older people’s needs for active and healthy aging? This qualitative study carried out in Italy and Romania in 2020 involved 30 participants: older adults, caregivers, and stakeholders. Based on a user-centered design approach, this study aimed to understand which requirements of ICT/sensing technologies could match people’s needs of active and healthy aging. Findings highlighted that ICT/sensing technology needs to focus on six major themes: (1) learnability, (2) security, (3) independence, empowerment, and coaching values, (4) social isolation, (5) impact of habit, culture, and education variables, and (6) personalized solutions. These themes are consistent with the Active Aging framework and the factors that influence perceived usefulness and potential benefits among older adults. Consequently, this study shows how well-known, but still unresolved, issues affect the field of information and communication technologies (ICTs) to promote active and healthy aging. This suggests that the reinforcement of the public health system, especially considering the pandemic effect, requires a concrete and formidable effort from an interdisciplinary research network.
