Accuracy of land parcel area measurement
(2012) Kwinta, Andrzej
In connection with direct subsidies to agriculture in European Union, each year hundreds of thousands of measurements of crops and allotments are performed. Area measurements are performed directly on site using geodetic or aerial photogrammetry methods. It is widely used for the control of the hand (navigation) satellite receivers. The receiver has recorded a trace of movement along the land. This measurement method is quick and not expensive. Comparison of results of measurements made in this type of technology with the allowable tolerance of an area shows that the theoretically obtained accuracy is sufficient. In real measurements a main source of error is improper identification of crops borders which – in many cases – are ambiguous.

Advanced Method for Determining Land Plot’s Physical Surface
(Wydawnictwa AGH, 2024) Malashevskyi, Mykola; Malashevska, Olena
"This study examines the issue of the accuracy of physical surface calculations for land plots with complex configurations and reliefs. The goal of the study was to develop a methodology for determining the surface area of land plots with complex configurations and reliefs. The presented model was based on the finite element method. The developed method allows one to evaluate a relief’s complexity by using a dimensionless mean physical surface complexity factor"," a Fortran program was developed for the methodology. Experiments that proved the effectiveness of the methodology and a comparative analysis of those areas that were calculated by the presented method and TIN model were carried out. The research findings proved the practicability of the methodology for calculating the physical surfaces of land plots with complex configurations. The presented methodology can be used for flood modeling, landscape and vertical planning, etc."
