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.

“…Building Information Management (BIM) is a concept that has revolutionized the possibilities of modelling and managing information about objects in the field of construction investments, from design, implementation to building management [10,15]. The versatility of this method allows you to document every part of the construction-related process -from the design stage, through the execution part, to the moment of acceptance and use of the objects [36,33,19,5,37]. It can be said that the essential and revolutionary aspect of this method is that the virtual image of a given object created thanks to it contains information processed in all three dimensions, which enables the ongoing updating of the project at every stage of its implementation.…”

The purpose of this work is to present the possibilities of using tacheometric measurement technology in the development of a 3D geometric model of an existing building and the directions of using BIM technology in the process of building operation. General information on the development of BIM technology was presented, and issues related to the construction of 3D models were discussed. Attention was also drawn to the need to update the information assigned to the model on an ongoing basis in order to effectively manage the building. Supplementing the model with metadata regarding the building materials used will allow for a precise and quick analysis of all renovation assumptions. The created 3D model can be used to control the condition of structures or in safety and risk management.

“…The higher the density of the point cloud, the higher the hardware requirements for data processing, but a dense point cloud is not always needed, as omitting some points does not necessarily degrade the quality of the virtual model representing the shape. There is a method for optimising a point cloud without loss of quality [2].…”

This article evaluates the accuracy of 3D models made from point clouds obtained from photogrammetry. Photographs were taken from ground level and using a drone, and data processing was performed in 3DF Zephyr. The models were compared with the actual dimensions of the buildings. Four different building objects with varying degrees of complexity were analysed. The aim of the research is to analyse the conditions for taking photographs and how they are transformed into a point cloud, and to see how and whether the complexity of the shape of the facade affects the accuracy of the 3D model made from the point cloud. The inaccuracy of the point cloud in the form of point spread for all analysed cases was 1.8±0.4 cm on average. The largest measurement error was found in the case of a multi-storey building. Despite the presented inaccuracies, it was considered advantageous to use the point cloud obtained through photogrammetry in the inventory. No difference was observed in the accuracy of the model depending on the complexity of the building. Recommendations were made regarding the conditions for taking photographs.
