“…e feasibility of oblique photogrammetry technology in the application of waterway engineering is verified. Yang et al [7] explored the influence of oblique photogrammetry on traditional cadastral management and its improved technology and pointed out that oblique photogrammetry technology can significantly reduce the cost of geographic information collection and promote the transformation of urban land management from 2D to 3D [7]. With the growth of computer computing power and UAV performance, inclination photogrammetry technology is bound to play a more and more important role in the planning and construction of various types of projects.…”

In order to better investigate the geological research, a tilt photogrammetry technology based on the unmanned aerial vehicle is proposed. This paper makes use of UAV tilt photogrammetry technology to make geological macroscopic analysis and establishes 3d color digital ground model, forming a set of technical methods for geological survey assisted by UAV. The experimental results show that the coordinate calculation is significantly improved, and the root mean square error of plane coordinates reaches 0.2 m, which can meet the requirements of later cartography and spatial measurement. The feasibility and efficiency of carrying out a geological survey based on the unmanned aerial vehicle are verified by the practical application in landslide hazard geological survey. It is proved that DEM and DOM data obtained based on oblique photogrammetry data can form various thematic maps by superimposing them with vector GIS data, which will provide a basic data model for subsequent engineering investigation, site management, and image display.

“…Космическая геоинформатика использует методы геометрии и методы определения координат, применяемые в фотограмметрии и геодезии. В этих науках принято называть определение координат засечкой (Yang, 2021). Одной из основных задач при исследовании планет с борта космического аппарата (КА) является исследование геометрии планет и координирования точек на их поверхностях.…”

The article relates to the field of space geoinformatics and comparative planetology. The difference between space geoinformatics and terrestrial geoinformatics is shown. The great connection of space geoinformatics with geometry is noted in comparison with terrestrial geoinformatics. The most common methods of planetary exploration are space imagery and radar sensing. Laser sensing is mainly used for ranging only. The article proposes to use laser rangefinders for a new purpose. The article proposes a new method for measuring coordinates on the planet's surface, called Trinitarian. The technique allows, on the basis of measuring the distance to a point, to determine two more of its coordinates. The technique is applicable when the spacecraft moves in the gravitational field of the planet as an artificial satellite. The coordinates are called conditional because they are not measured in the coordinate system of the planet's surface or in the system of its center of mass, but in the coordinate system associated with the trajectory of the spacecraft. An analogy between this technique and the measurement of coordinates using global navigation satellite systems is shown. Coordinates are measured by measuring the range from two points of the spacecraft trajectory and measuring the baseline on the trajectory between the observation points. Calculation formulas are given and errors are analyzed. The relativity of coordinates is that the technique allows you to measure only two coordinates out of three. The technique is compared with the terrestrial analogue of the global navigation satellite system. The similarities and differences between the proposed Trinitarian methodology and the existing global navigation satellite system are shown. Further improvement of the methodology is proposed.

“…The geometrical accuracy of georeferenced digital surface models obtained from images captured by UAVs and processed by using SfM photogrammetry focused on the number and location of ground control points were analyzed in [28,29]. Recent studies have been conducted to evaluate the accuracy of a large-scale topographic map of oblique photogrammetric air survey [30]. The accuracy of the 3D model and the quality of the orthophoto in UAV photogrammetry can be affected by several general conditions, such as camera settings, images resolution, high contrast, uniform surface area, number of control points and correct placement, and much more.…”

Current surveying techniques are typically applied to survey the as-is condition of buildings, brownfield sites and infrastructure prior to design. However, within the past decade, these techniques evolved significantly, and their applications can be enhanced by adopting unmanned aerial vehicles (UAVs) for data acquisition, up-to-date software for creating 3D reality mesh, which in turn opens new possibilities for much more efficient construction site surveying and constant updating and process management. In this study the workflows of three UAV-based photogrammetry techniques: Real Time Kinematic (RTK), Post-Processing Kinematic (PPK) and Global Positioning System (GPS) based on control points were analyzed, described, and compared to conventional surveying method with Global Navigation Satellite System (GNSS) receiver. Tests were performed under realistic conditions in 36 ha quarry in Lithuania. The results of the relationship between ground sample distance (GSD) and the comparison of volume measurements under each technique, including conventional method were analyzed. The deviation of data collected on field vs. generated in reality mesh, including ground control points (GCPs) and check points (CHPs) with different configurations, was investigated. The research provides observations on each workflow in the terms of efficiency and reliability for earthwork quantity estimations and explains processing schemes with advanced commercial software tools.
