The description of parcel geometry and its application in terms of land consolidation planning

•The analysis of land fragmentation.•Description of parcel geometry using the proposed indicators.•Determination of parameters to assess the failure of flawed structures of parcels.•Example application of proposed indicators describe the geometry of parcel.

Land consolidation is the current issue occurring around the world. In the course of consolidation works the state of fragmentation of farms and its impact on their productivity is analyzed. Various methods of fragmentation assessing and variants of implementation of consolidation procedures are being developed. There are many factors of a different nature affecting the need for consolidation. One of the basic elements needed in these works is a quantitative description of flawed shape of plots based on the parameters of their spatial shape. GIS systems allow quick collection of spatial data of the plots or any other surface structures, including parcels. In this paper we focus only on the geometric shape of a parcel as a condition to carry out the consolidation. The paper proposes a methodology for obtaining parameters of the geometry of parcel description, which supports the process of decision-making in the field of land consolidation works. In this paper we proposed an algorithm to replace parcel with equivalent rectangle (ER). The presented solution enables quick processing of the large amounts of data. The results of algorithm use are shown on the example of the fragment of village in the Southern Poland.
