Land consolidation in rural areas is greatly influenced by a number of social, agricultural, and economic factors. They extend the time and complicate activities related to the implementation of this project. Land consolidation is a huge investment, requiring a good and up-to-date map. Up-to-date data that reflects reality are the basis for good and efficient land consolidation in rural areas. To improve the creation of a land consolidation project, the most appropriate solution would be to place all the necessary data to create a land consolidation project on “geoportals” websites. Providing data on the websites of geoportals in Poland and Finland in the form of a map portal would enable both visual and substantive analysis of spatial changes in rural areas. Therefore, this article pursues two main scientific goals. The first purpose of this article is to analyze the history and scope of land consolidation in Poland and Finland in order to learn the specifics of land consolidation in a given country. Comparisons and analyses were made on the basis of the authors’ experience in Poland and Finland with land consolidation in the areas described. The second scientific goal of the article is to compare the availability of geospatial data in the context of the methodology of performing land consolidation in rural areas, which leads to increased energy efficiency in agricultural production by reducing the need for energy, especially fuel for agricultural machinery. The results from the table with a list of geoportals in Poland and Finland are a summary of the data available for free. Thanks to it, land consolidation contractors around the world will have the opportunity to familiarize themselves with and perhaps use this data when creating a rural land consolidation project. Good land consolidation planning will lead to effective and economical use of rural space. This is part of the 2030/2050 strategy. Reducing agricultural production costs, lower fuel consumption, and a smaller carbon footprint. This is what Poland and Finland are striving for as countries belonging to the European Union.

“…Suppose the real coordinates of the current point are 3,5 (in the Cartesian coordinate system) and its ideal coordinates are 3.07,5.83 , we can obtain the nearest point in the Cartesian coordinate system [12] according to the rule closest to the ideal coordinates by drawing a square with side length 2range centered on the real coordinates of the current point. At first, let this point be in the lower left corner of the square, and set a displacement precision [13] (the distance of each movement in the positive direction of the x-axis or in the positive direction of the y-axis.…”

When the UAV cluster is attempting formation flight, electromagnetic silence should be maintained as much as possible to avoid external interference, and few electromagnetic wave signals should be emitted outward. In order to maintain the formation, a purely azimuthal passive positioning method is proposed to adjust the position of UAVs. In order to reduce the deviation of the UAVs from the ideal position, we first establish an optimization model by finding the closest position to the ideal coordinates of each receiving UAV under the constraint rule as the objective function, and use the signal UAV traversable coordinates as the constraint, establish an iterative optimization distance model, and use the traversal algorithm and iterative algorithm to find out the ideal position of the UAV under the constraint, and finally be able to reduce the total actual deviation of the UAV to about 0.159 m.

“…To address this issue, various studies have been conducted to model the errors in a solution [107,108]. It has demonstrated that the precision of a GBRI system can reach up to a sub-millimeter level when artificial targets are measured [109][110][111][112]. Due to the high precision and adjustable observational geometry of a GBRI system, it has been widely used in urban infrastructure stability monitoring, including both large-scale and individual-target monitoring [24].…”

Urban infrastructure is an important part of supporting the daily operation of a city. The stability of infrastructure is subject to various deformations related to disasters, engineering activities, and loadings. Regular monitoring of such deformations is critical to identify potential risks to infrastructure and take timely remedial actions. Among the advanced geodetic technologies available, radar interferometry has been widely used for infrastructure stability monitoring due to its extensive coverage, high spatial resolution, and accurate deformation measurements. Specifically, spaceborne InSAR and ground-based radar interferometry have become increasingly utilized in this field. This paper presents a comprehensive review of both technologies for monitoring urban infrastructures. The review begins by introducing the principles and their technical development. Then, a bibliometric analysis and the major advancements and applications of urban infrastructure monitoring are introduced. Finally, the paper identifies several challenges associated with those two radar interferometry technologies for monitoring urban infrastructure. These challenges include the inconsistent in the distribution of selected measurements from different methods, obstacles arising from rapid urbanization and geometric distortion, specialized monitoring techniques for distinct urban features, long-term deformation monitoring, and accurate interpretation of deformation. It is important to carry out further research to tackle these challenges effectively.
