Point error research on fast calculating construction deformation observation control point based on Adobe Acrobat Software and CASIO program

Adobe Acrobat 7.0 Professional Software can be used in engineering technology. We can conveniently measure the length between the straight lines (two points) and its correspondence increment of coordinate in the drawings by making use of this software function. In addition, we can choose different angle observations and the precise of distance observations (such as electronic tachometer), provide a new method for fast and accurately calculating the error of the traverse point and carrying out the plan of optimized measure and calculation point error by using the programmed calculator fx-4500p as well as the program developed by the author himself.
