If angular measurements are more precise than linear measurements... use transit method
1:12:42 pe jo 1st globe ha uspe,jo longitude and latitude bta rha ha ,vo confusion dalti ha,vo btana to 2 lines chahti ha,lakin direction lag rhy ha
Thanks sir ji 🙏👍🙏

Vertical clif.... contour line overlap
Thanks a lot for everything sir.
Thanks🙏🙏 sir
Direct levelling...
Simple levelling

RF ... representative fraction
thankyou so much sir
Tachometer..... transit theodolite
thank you sir
1 nautical mile....1852 m...1.8 km
Method of orientation.... resection
Accuracy.... degree of perfection obtain or achieved
Setting, levelling, elimination of parallax
