“…Secondly, the main distinguishing feature of this work from the previous studies [10,11,24,25,29,31] is the creation of a geotechnical map that was built for the driven piles. According to the geological structure of the foundations, the optimal variations in the pile length for each city zone were determined.…”

Development of a geotechnical database for the young capital of Kazakhstan, Nur-Sultan city, became a paramount concern of both the scientific community and industry. The creation of the Kazakhstan model of the geotechnical database was based on a fixed dataset which included a city map with determined X, Y, and H coordinates and the user generated data obtained from the materials of engineering and geological surveys from more than 2000 boreholes. Based on the assessment of the built-up area of the city, six main engineering-geological elements (EGE) were identified. The territory of the city was regrouped into eight zones instead of the previous six based on the geological origin and stratigraphy interposition of the EGE. Engineering properties of the soils were considered for physical and mechanical characteristics, where the plasticity limits demonstrated an accurate correlation to the elasticity modulus E and distribution boundaries between the alluvial and eluvial types of the soil on the graph. So, the increased liquid and plastic limits are replicated by higher values of elasticity modulus E, and hence better strength characteristics of a particular soil layer and vice versa, while the moisture content and soil density did not show any obvious pattern and requires additional verification on the construction site. Finally, a geotechnical map was built for the driven piles and the optimal variations in the pile length for each zone were determined.

“…GIS tools can be used for the following purposes: integrating existing data with project-specific data, identifying potential environmental and geological hazards, planning and tracking fieldwork, producing maps and figures, and improving communication [ 14 , 15 ]. Early in the design process, these tools can assist in identifying potential barriers that may hinder project completion or agricultural production and avoid costly rework later on [ 8 , 11 , 12 , 16 , 17 ].…”

“…A geographic information system (GIS), by itself or associated with satellite images, is an effective tool for organizing, analyzing, and presenting the horizontal spatial variables of the soil properties and conditions [4][5][6][7]. Soil specialists, irrigation engineers, environmental engineers, and geotechnical engineers can use GIS maps for preliminary assessments and final geotechnical designs [4,[8][9][10][11][12][13]. GIS tools can be used for the following purposes: integrating existing data with projectspecific data, identifying potential environmental and geological hazards, planning and tracking fieldwork, producing maps and figures, and improving communication [14,15].…”

This study aims to produce digital maps showing the physical and hydraulic soil properties of the Al-Ahsa Oasis in Saudi Arabia by employing the capabilities of the GIS technique. These maps can display the pattern distribution of different physical and hydraulic properties of soil accurately and accessibly. Recently developed local pedotransfer function (PTF) models were applied to the basic soil data of earlier research covering 566 points. An analysis was conducted using a spatial interpolation technique of the GIS program. Maps of spatial patterns described essential soil physical and hydraulic properties such as sand%, silt%, clay%, bulk density (ρ), saturation (θs), field capacity (FC), wilting point (WP), and soil water characteristic curve (SWCC) fitting parameters b, c, d. Sand dominates most of the study area, particularly in the northeast near Hufof. This may be attributed to the deposition of drifting sand and dune movement. Silt and clay increased in other locations. Bulk density ρ was positively increased with sand and negatively with silt and CaCO3 content. Soil hydraulic properties (θ, FC, WP, and SWCC fitting parameters b, c, d) were positively correlated with silt and ρ and negatively with sand content. This digital map can be employed for a general overview investigation, for the whole studied area, for agricultural expansion and for environmental studies.

“…An analyses of Metro Manila soil bearing capacity in Philippine using the GIS have been performed [5]. The list extends to many different soil characteristics such as land suitability [6], seismic risk assessment [7][8][9], Landslide susceptibility [10], sulfate content [11,12], the bearing capacity [13][14][15], and gypsum content [16]. However, there are few studies concerning the angle of internal friction, which is a shear strength parameter that is very significant in assessing the stability of soil and slopes as it reflects the soil shear resistance [17].…”

The angle of internal friction value (φ) is used to describe the soil resistance to shear failure. It is estimated experimentally either from Direct Shear Test or Triaxial Stress Tests. Because of the high cost needed for conducting field tests, it has become essential to find alternative and practical methods to predict soil characteristics for non-spatial data areas. The objective of this study is to specify the best interpolation method to predict the angle of internal friction and use it to produce geotechnical maps for parts of An-Najaf province-Iraq; these parts are the city centre An-Najaf and Kufa city. Furthermore, the study describes the strength and type of soil strata. The results show that the Local Polynomial Interpolation (LPI) is the ultimate and the most significant method to interpolate the angle of internal friction. Moreover, the angle of internal friction φ values is ringing between (20-46) degrees, which represent medium to dense soil resistance to shear, while the mean values of φ ranged between 34.3 - 36.18 and represent good resistance to shear failure. This indicates that the Density of Sand is medium to dense, and N60 values range from 10-50. This kind of map would ease the engineers and decision-makers to decide the suitability of the construction site to carry loads, and the selection the foundation type. The benefits also extend to selecting urban expansion alternatives and for the delimitation of future trends for land-use-development processes in the metropolitan area of An-Najaf city, mainly at local and regional scales.
