“…UAV technology has made it possible to acquire high-resolution and real-time aerial photographs for photogrammetry in order to determine the potential slope hazard location [14]. Additionally, human activities such as slope excavation, construction activities, deforestation, or other land use are considered true causes of slope failures or landslides [15].…”

This paper discusses the applications of unmanned aerial vehicle (UAV) for slope mapping and its important parameters including perimeter, area and volume of certain selected areas at Perumahan Taman Gambang Damai in Kuantan Pahang. This study also focused on determining the potential slope hazard based on slope angle. Modern UAV able to take high quality image which essential for the effectiveness and nature of normal mapping output such as Digital Elevation Model (DEM) and Digital Orthophoto. This photo captured by the UAV will later transfer to Agisoft to generate full map of study area. With the help of Global Mapper, the measurement (perimeter, area and volume) of selected study areas can be determined easily and considered as the main interest in this study. In addition, another outcome of this study is, this modern method of mapping helps researchers and engineers to study the possibility of slope hazard based on their respective slope angle (according to slope classes). In conclusion, modern technology of UAV proves to be very effective for mapping in geotechnical engineering. Slope mapping help researchers and engineers to obtain slope measurement within short period of time compare to previous traditional method.

“…These movements are mostly due to the instability of rock masses from the slopes, whose main constituents are soil, fractured rocks, and weathered materials. [16][17][18][19][20][21][22][23] Weakness zones are those areas whose mechanical properties are considered as significantly lower compared to the surrounding rock masses. It can occur as fault zones, shear zones or weak rocks and most of these zones are the results of numerous ruptures undergoing over geological time.…”

Vertical Electrical Sounding (VES) technique which employs the Schlumberger depth sounding method was used to investigate the subsurface conditions at the landslide in Perizie colony, Kohima. The interpretation of the VES curves shows differing lithology consisting of weathered shales with associated clay, which is considered an important factor for slope instability. The shear strength of the slope materials, including the country rocks and the soil cover, is also significantly reduced and easily detached due to the effects of weathering and erosion, causing the landslides. Three to six possible geo-electric layers are delineated from the variations in the resistivity values, with the lithologies consisting of topsoil followed by alternate layers of weathered and fractured rocks of varying thickness. The analysis also points to the presence of a weak zone at a depth of about 10 m, which is not apparent from the surface. The formation of groundwater aquifers in the fractured zones indicates high risk for slope failure as this accelerates the weak country rocks to weather. The results obtained by this study correspond well with the available borehole data of the area.

“…Engineers and geotechnical researchers may be able to work together more quickly and safely through the utilization of UAVs since they enhance their ability to detect possible slope failures, critical slopes, and slope hazards, as stated by Zolkepli et al [10], Ishak, & Zolkepli [11], Zolkepli et al [12], and Bar et al [13]. UAV flight technology has enabled the acquisition of high-resolution, real-time aerial pictures for photogrammetry to detect the location of potential slope hazards [14], [15].…”

This paper highlights the work of slopemapping utilizing the unmanned aerial vehicle (UAV) with its perimeter, area, and volume of particular regions chosen at Gambang Damai Residents in Kuantan Pahang. The location selected was choose because of its proximity to the study area. Slope mapping has traditionally been time-consuming and challenging, especially in hilly areas. This research also aimed to identify potential slope hazards based on slope angle. The accuracy and nature of typical mapping outputs, such as the Digital Elevation Model (DEM) and Digital Orthophoto, depend on high-quality photos that modern UAVs can only capture. These photographs taken by the UAV will be transferred to Agisoft software to generatea complete map of the study area. With the help of Global Mapper, it's easy to measure elements such as the perimeter, area, and volume of selected study areas, which is the main point of this research. The results of the two slopes (slope A and slope B) show that slope B produces a massive volume of 1469.7 m3, whilst slope A generates just 1382.9 m3. Slope A has an enclosed area of 1634.3 m2, which is more significant than slope B's enclosed area of 766.86 m2.Additionally, slope A's perimeter is 162.28 m, more extensive than slope B's 159.45 m. Another result of this research is that researchers and engineers may evaluate potential slope hazards using a contemporary mapping approach by determining their particular slope angles. According to the findings, slope A has an angle of 47.35⁰, while slope B has an angle of 54.75⁰. Both slopes considered to be very steep. In conclusion, using current technology, such as UAVs, is quite beneficial when mapping in geotechnical engineering. Researchers and engineers can gather slope measurements more quickly than with previous traditional approaches by adopting multi-rotor UAV slope mapping.
