you are the MAN Donald..thanks for sharing this with us

not sure what you mean by "not enough space to present"  because you can upload presentations, videos, graphics etc.
• @Saleem: I guess the space this venue provides is not enough to discuss how to do data reduction using Excel. In addition, it requires some graphic presentation to significanlty reduce the learning curve. Cheers..

• all  lsu member please tell me how can adjust the level and coordinate in excell. thank u

• Sometimes we are prompted to relate degree values to slope values in the field. Usually, our instrument only provide as degree values for vertical angles. How about if you're asked for a slope value corresponding to a given measured degree value? Just hit the tan function button in your calculator for that degree value and get the corresponding slope value.

• Land Surveyor

A good base for understanding the triangle, the simplest polygon, which is, in the main, the most important to the Professional Land Surveyor, is the foundation of all other calculations.
• to establish the chord...... Sin of Delta X Rad dist...... This should give you your chord but watch those significant digits, cuz if you round too early, it will be wrong.....lol..... again, hope it helps.
• (DELTA ANG/ 360 DEG) x ( PIE X 2 RAD) = LENGTH OF ARC. This formula shows that the delta ang establishes the percent of a circle, and that percent is directly proportional to the length of circumference it projects.....This can be done on a cheepy calc and needs minimum info. Hope this helps someone out there.
