Abstract: The question undertaken in the research was: how does the number of measurement points influence the error of the land parcel's area calculation? The field measurements relied on continuous land parcel's GPS measurement with various intervals of the record. Simulated area accuracy calculated from Gauss's formula increases with the increase number of points. The experiment of continuously GPS measurement did not confirm simulated accuracy in all points¿ number range. The largest difference was observed for few number of measuring points, for which the prognosis error was much bigger (almost 2 times) than the error obtained during measurements. A relationship between amount of the points and area accuracy was also compared with the literature (Bogaert i et. al. 2005). The results of our research also only partly confirmed results published in the literature. Main discrepancy was observed for small point¿s amount. In our research, area error increases with decreasing number of points, in the literature on the contrary area error decreases. Explanation of this phenomenon requires further research especially because that our field measurements not correspond full to the simulation from the literature.
