تقييم دقة حساب مساحات قطع الأراضي بالطرق المختلفة

الملخص EN

The article aims to evaluate the accuracy of the methods used to find areas for plots of land, which are calculated on different reference surfaces from maps and plans or from field cadastral measurements.

There are three methods used to calculate the area, viz.

analytical, planning and mechanical.

The analytical method is the most important and accurate of these methods.

The study focuses on analytical methods, which depend on surveying meteorology, where they were implemented on the plot of land studied, firstly by measuring the coordinates of its corners and secondly by dividing it into two triangles and measuring the lengths of the sides and thirdly as a trapezoid and the measurement of the bases and the height.

The schematic method was also used by taking the coordinates from the area plan, calculating the area using MS Excel, and finally calculating the area of the studied piece of the stereogram resulting from aerial photographs.

The study concludes with a number of results and recommendations, the most important of which are: calculating the area of a plot of land by analytical methods is the most accurate, with a relative error of 1:1000, and that the planning methods for calculating the area are the least accurate, with a relative error of 1:100.

The study recommends using the triangles method instead of the quadrilaterals when dividing the plots into geometric shapes for the purpose of calculating the area, as the accuracy of the area of the triangle is 1.4 times greater than the accuracy of the quadrilaterals.
