- Cálculo de delta norte y delta este :
- Delta norte:
- ΔN1-2 = N1 – N2 =1.130.804,640 m - 1.130.786,630 m = 18,010 m.
- ΔN2-3 = N2 – N3 =1.130.786,630 m - 1.130.715,840 m= 70,790 m.
- ΔN3-4 = N3 – N4 =1.130.715,840 m - 1.130.792,260 m = -76,420 m.
- ΔN4-5 = N4 – N5 =1.130.792,260 m - 1.131.027,890 m = -235,630 m.
- ΔN5-6 = N5 – N6 =1.131.027,890 m -1.131.264,120 m = -236,230 m.
- Delta este:
- ΔE1-2 = E1 – E2 = 754.365,920 m - 755.292,060 m = -926,140 m.
- ΔE2-3 = E2 – E3 = 755.292,060 m - 755.513,070 m = -221,010 m.
- ΔE3-4 = E3 – E4 = 755.513,070 m - 755.810,210 m = -297,14 m.
- ΔE4-5 = E4 – E5 =.755.810,210 m - 756.225,960 m = 415,750 m .
- ΔE5-6 = E5 – E6 =.756.225,960 m - 756.301,880 m =-75,920 m.
