Estimation of the value of land, underlying the design of constituent plots of the farmstead, is a decisive element of the complex procedure of land consolidation and exchange. Correctly estimated value of agricultural land is a prerequisite for adequate and equitable delimitation of land plots to improve the living conditions of local residents and ensure efficient and profitable agricultural activity. The dynamic development of technology contributes to the development of multiple tools, considerably improving design works and field surveys in the land consolidation process. The world reference literature also gives numerous examples of surveys to optimise the methods for estimating a land value for consolidation projects. However, in our opinion, despite a vast collection of self-designed calculation methods, available sources insufficiently address the optimisation of existing methods based on the current legal framework and implementing practices. This paper presents a self-designed solution for the fully automated performance of complex comparative estimation of land based on the existing cadastral data and a simplified array showing the estimated value. The tool resulted in developing a set of data for directly importing the outcomes of calculations into land surveying software supporting steps of the land consolidation process. Following detailed evaluation, the proposed self-designed solutions were implemented at the Subcarpathian Office of Land Surveying, and Agricultural Areas in Rzeszow for land consolidation works in the Subcarpathian voivodeship in southeastern Poland.
