Consolidation works are a complicated and lengthy set of legal, technical and administrative operations. IT tools used in this process are developed in many countries, and the scope of their functions is very wide: from a decision-making aid, through support in solving technical aspects, to assisting the evaluation of the effects of consolidation projects. Practically all existing solutions are based on GIS systems, which has many advantages but also imposes some limitations related to supporting typically geodetic aspects of these works. The article presents a different approach to implementing this kind of projects, which is based on CAD platform. It is used as an aid in various stages of land consolidation works in more or less half of the area of Poland.

The development of modern technologies and accessibility of data on space and the natural environment has led to their increasing use for socio-economic purposes. Data users believe that these systems reflect the reality in the field. This applies in particular to databases used for construction investment projects or as the basis for calculations of financial obligations, e.g., taxes. The Land and Property Register (LPR), which is part of the Land Administration System, serves a number of economic and legal purposes. This geo-system often contains low-quality information regarding the technical potential of modern data acquisition methods and is continuously updated. The authors propose a two-step analysis of data contained in the LPR. The first step identified the sources of discrepancies between data from the LPR and the reality in the field. The second step emphasises the importance of the factors under analysis, which include both a plot’s geometric parameters, the geo-location features (associated with the natural environment elements) and factors associated with the supplementary data acquisition methods. The results show that sufficient quality data play the main role in achieving compatibility between the data in the Land and Property Register and with reality. Studies conducted so far have dealt with data on a global scale and were based on in situ data and focused on the specific values of each plot under analysis.

“…Computation of topological relations is indispensable for spatial cognition (Klippel 2012), spatial queries (Clementini et al 1994;Hu et al 2013), spatial data visualizations (Clark et al 1997;Agugiaro and Kolbe 2012), and many other geographical analysis tasks (e.g. Ledoux and Meijers 2011;Shiode and Shiode 2011;Siejka et al 2014).…”

Classical topological relation expressions and computations are primarily based on abstract algebra. In this article, the representation and computation of geometry-oriented topological relations (GOTR) are developed. GOTR is the integration of geometry and topology. The geometries are represented by blades, which contain both algebraic expressions and construction structures of the geometries in the conformal geometric algebra space. With the meet, inner, and outer products, two topology operators, the MeetOp and BoundOp operators, are developed to reveal the disjoint/intersection and inside/on-surface/outside relations, respectively. A theoretical framework is then formulated to compute the topological relations between any pair of elementary geometries using the two operators. A multidimensional, unified and geometry-oriented algorithm is developed to compute topological relations between geometries. With this framework, the internal results of the topological relations computation are geometries. The topological relations can be illustrated with clear geometric meanings; at the same time, it can also be modified and updated parametrically. Case studies evaluating the topological relations between 3D objects are performed. The result suggests that our model can express and compute the topological relations between objects in a symbolic and geometry-oriented way. The method can also support topological relation series computation between objects with location or shape changes.
