not sure what you mean by "not enough space to present"  because you can upload presentations, videos, graphics etc.
Reply by Arnel M. Domag on April 3, 2011 at 9:02am

@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.

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.
